How do I reset a CP-7940 or CP-7960 to factory default?

This will describe how to Reset the Cisco CP-7940 and CP-7960 IP Phones to the Factory Default. This procedure assumes that you do not know the unlock password as there is another procedure for resetting a phone if you do know the unlock password.

]]> Complete the following steps:

Unplug the power cable from the phone, hold dows the # key, and then plug the power cable in again.

The phone begins its power up cycle.

Release the # key after the Speaker button is no longer lit.

You should see the following message on the phone:
"Reset key sequence detected"

Press 123456789*0# within 60 seconds after the Headset, Mute, and Speaker buttons begin to flash.

If you enter this key sequence correctly, the phone displays this prompt:

Keep network cfg? 1 = yes 2 = no

In order to maintain the current network configuration settings for the phone when the phone resets, press 1. In order to reset the network configuration settings when the phone resets, press 2.

How do I unlock a Cisco CP-7960 running SIP software?

Product: Cisco CP-7960 and CP-7960G

In SIP releases 4.2 and later, an Unlock Config item displays in the phone settings menu. When you select Unlock Config, you are prompted to enter a phone password. When the correct password is entered, the configuration is unlocked and the settings can be changed. When the Network Configuration or SIP Configuration menus display, the lock icon in the upper-right corner of the LCD indicates an unlocked state. The unlocked symbol indicates that you can modify the network and SIP configuration settings. When the Settings menu is exited, the phone automatically relocks the configuration.

]]> In releases before 4.2, you press **# in order to unlock the SIP IP phone configuration menu.

The default password to unlock a Cisco CP-7960 or CP-7960G running SIP software greater than 4.2 is:

"cisco"

This password is for SIP phones only and does not work for any other software including SCCP or MGCP.

What is the difference between a Cisco WS-C2948G and a WS-C2948G-L3?

We often get asked what the difference is between a Cisco WS-C2948G-L3 and a WS-C2948G. The most obvious is the L3 on the end of that part number. But what exactly does L3 mean?

]]> Here are the exact descriptions taken from Cisco's website.

WS-C2948G - Derived from Catalyst 4000
-Supervisor Engine I
-48 10/100BaseTX switch ports + 2 1000BaseX Gigabit Interface Converter (GBIC) switch ports

WS-C2948G-L3 - Derived from Catalyst 8540
-48 10/100BaseTX Ethernet processor interface (EPIF) + 2 1000BaseX GBIC Gigabit processor interface (XPIF) Layer 3 switched interfaces

The Cisco WS-C2948G-L3 is a Layer 3 switch and runs Cisco IOS Software while the Cisco WS-C2948G is a Layer 2 switch and runs Catalyst 4000 software.

How do I reset password on a AIR-BR342 running 8.65 or earlier

This articles describes the procedure for resetting / upgrading a Cisco AIR-BR342

Model: AIR-BR342
Console Cable: straight through cable

]]> Warning: This procedure will remove the configuration. Be sure to have a backup of your current configuration before proceeding.

Prerequisites: You will need an AIR-BR342 running code later than 8.65. You will also need a 9-pin male adapter to connect to the console port.

Step 1: Connect the console cable to the bridges and start your terminal program (Hyperterminal if using Windows). Console port settings are 9600,8,N,1 by default.

Step2: Connect the 2 bridges to your network and power them on

Step 3: from the bridge that that has the latest code choose the following options:
5 – Diagnostics
7 – Load
4 – Distribute
1 – Go
Are you sure [y/n]? Y
You should see it loading.

Step 4: switch over to the upgrading bridge. When it is finished loading choose option 2 - Reset and press Y to reset the configuration. This will set it back to factory default.

How do I reset the password on a Cisco WS-C3550-48-SMI?

This articles describes the procedure for resetting / recovering the password on a Cisco Catalyst WS-C3550-48-SMI.

]]> Model: WS-C3550-48-SMI
Console Cable: Cisco Blue
Warning: This procedure will remove the switch configuration. Be sure to have a backup of you current switch configuration before proceeding.

The Cisco WS-C3550-48-SMI Catalyst switch is similar to most Catalyst switches and the procedure for resetting the password is the same.

Step 1: Connect the console cable to the switch and start your terminal program (Hyperterminal is using Windows). Console port settings are 9600,8,N,1 by default.

Step 2: Hold the MODE button (on the front of the switch) while you power on the switch.

Step 3: Hold the MODE button for a few seconds until you the System light stop flashing.

Step 4: At this point, the switch should be in ROMmon mode.

Step 5: From ROMmon mode, type: FLASH INIT

Step 6: From ROMmon mode, type: DELETE FLASH:config.text

Step 7: From ROMmon mode, type: boot

At this point the switch will boot as normal with a new configuration and no password.

What is the difference between a AIR-PWRINJ and a AIR-PWRINJ3?

While both the AIR-PWRINJ and AIR-PWRINJ3 are listed as Aironet power injectors, they don't support the same Aironet radios.

]]> These power injectors provide up to 15 watts over a Category 5 Ethernet cable, supplying enough power to support up to a 100-meter cable run.

The AIR-PWRINJ is compatible with the Cisco Aironet 350 Series Access Point and bridges. The AIR-PWRINJ3 is compatible with the Cisco Aironet 1100 and 1200 Series Access Points.

Cisco Aironet 350 Series Access Points and Bridges
Supported Power Injector: AIR-PWRINJ
External Power Supply: None Required

Cisco Aironet 1100/1200 Series Access Point
Supported Power Injector: AIR-PWRINJ3
External Power Supply: AIR-PWR-A (required)

Note: Cisco AIR-PWRINJ3 power injectors can be used with Cisco Aironet 350 Series devices, but the AIR-PWRINJ power injectors cannot be used with the Cisco Aironet 1100/1200 series devices.

What is the difference between a WIC-1DSU-T1 and a WIC-1DSU-T1-V2?

We often get asked by our customers what the difference is between a WIC-1DSU-T1 and a WIC-1DSU-T1-V2 T1 Wan Interface Card for Cisco routers.

]]> Apart from price (as of this writing, the WIC-1DSU-T1-V2 is the more expensive of the two) the WIC-1DSU-T1-V2 offers all of the same features of the WIC-1DSU-T1. Cisco describes the WIC-1DSU-T1-V2 as an "updated" version of the older WIC-1DSU-T1 (which has been officially End-Of-Lifed).

But what exactly does "updated" mean to you. The following is a table showing the differences which do not affect most installations.

WIC-DSU-T1

One-port T1/fractional T1 DSU/CSU WIC

Supported on: 1600(2) , 1600R(2), 1700(3) , 2600, 2600XM, 3600, and 3700

Wet T1 Capable: No

Short Cable Length Command: No

Network Equipment Building Standards (NEBS): No

WIC-1DSU-T1-V2

Updated one-port T1/fractional T1 DSU/CSU WIC

Supported on: 1700(1) (1720, 1721, 1751, 1760), 2600XMs, 2691, 3631, 3725, 3745, and ICS 7750

Wet T1 Capable: Yes

Short Cable Length Command: Yes; used to configure attenuation for short cable lengths (<660 feet)

Network Equipment Building Standards (NEBS): Yes (Type I/III)

NOTE: The Cisco 1750 Router does not support the newer version, WIC-1DSU-T1-V2

What are the requirements to upgrade to a SUP720?

We recently upgraded one of our Supervisor 2 Engines on our Catalyst 6509 Switch to a Supervisor 720. We thought it would be a simple upgrade but quickly realized it wouldn't be that simple.

]]> Model: WS-C6509 Catalyst Switch w/ WS-SUP720 Supervisor Engine

Compatible with the following chassis:
Cisco 6503, 6503-E, 6506, 6506-E, 6509, 6509-E, 6509-NEB, 6509-NEB-A, 6513
Cisco 7603, 7606, OSR-7609, 7609, 7613

We installed the SUP720 in a Catalyst 6509 Switch with a standard WS-CAC-1300W power supply and a standard FAN tray.

Upon boot, the supervisor engine ran diagnostics and soon after diagnostics were completed failed due to the FAN tray not being compatible. A quick glance at Cisco.com and we realized that the FAN tray would need to be upgraded to a high-speed fan.

We installed the following:
WS-C6K-9SLOT-FAN2 Cisco Catalyst 6509 high-speed fan tray

We booted the unit up again and this time the diagnostics resulted in an error having to do with the power supply not being compatible with the high-speed fan tray. We now realized that the high-speed fan tray requires a WS-CAC-2500W power supply.

We installed the following:
WS-CAC-2500W 2500W AC Power Supply

At this point the SUP720 worked fine and we were able to complete the upgrade.

Summary: A WS-SUP720 on a Catalyst 6509 Chassis requires an upgrade to both the FAN tray and Power supply.

How do I recover from a bad image on a Cisco WS-X4232-L3?

This article describes the process required to recover a Cisco WS-X4232-L3 Catalyst 4000 module due to a missing or corrupted system IOS image.

]]> The Cisco WS-X4232-L3 Layer 3 module runs Cisco IOS software. It is equiped with bootflash, usually 16MB in size. If the IOS software on the bootflash is either missing or is corrupt, the module will fail to load properly and you will be stuck in ROMMON mode.

This procedure involves the loading of a new software image via the console port using the xmodem feature found in ROMMON. The best terminal emulation software to use for this procedure is Microsoft Hyperterminal (found in most Microsoft OSs).

1. Launch Hyperterminal and connect to the console port on the WS-X4232-L3 module using 9600,8,N,1 as your connection settings.
2. While in ROMMON mode type the following:

xmodem -y -s38400

3. Note, if the console port is attached to a modem, both the
console port and the modem must be operating at the same baud
rate. Use console speed 38400 bps for download [confirm]

4. Press Enter to confirm and immediately disconnect your session using the disconnect icon on the Hyperterminal toolbar.

5. Click on File -> Properties and then Click CONFIGURE.

6. Change the baud rate to 38400 and click ok.

7. Reconnect using the connect icon on the Hyperterminal toolbar.

8. Initiate the file transfer by clicking on Transfer -> Send File.

9. Choose Ymodem and select the IOS image to transfer.

10. Once the image has been transfered (while take a while at 38400), the system will ask you to press Y to confirm the switch back to 9600. At this point, DO NOT hit the Y key.

11. Disconnect the session using the Disconnect icon in Hyperterminal.

12. Click on File -> Properties and then CONFIGURE.

13. Change the baud rate to 9600 and click ok.

14. Connect using the connect icon on the Hyperterminal toolbar.

15. Hit the Y key to continue. At this point the system should load the IOS image as normal.

Once the IOS software has loaded you will want to copy the image to bootflash.

1. Assign an IP Address on the Gigabit interface (or Fast Ethernet)

router# conf terminal
router(config)# int gig 1
router(config-if)# ip address 172.16.38.235 255.255.0.0
router(config-if)# no shutdown
router(config-if)# exit
router(config)# exit

2. Copy IOS image to flash.

router# format bootflash
Format operation may take a while. Continue? [confirm]
Format operation will destroy all data in "bootflash:".
Continue? [confirm]
Formatting sector 1
Format of bootflash: complete

router# copy tftp flash
Address or name of remote host []? 172.16.38.25
Source filename []? cat4232-in-mz.120-25.W5.27b.bin
Destination filename [flash]? bootflash:cat4232-in-mz.120-25.W5.27b.bin
Accessing tftp://172.16.38.25/cat4232-in-mz.120-25.W5.27b.bin...

Loading cat4232-in-mz.120-25.W5.27b.bin from 172.16.38.25 (via GigabitEthernet2

3. Set the system boot variable to boot from the new image.

router# config terminal
router(config)# boot sys flash bootflash:cat4232-in-mz.120-25.W5.27b.bin

4. Write configuration to memory and reload.

router# write mem
router# reload

What is the procedure for upgrading a WS-X6K-S1A-MSFC2 to the lastest software?

Follow these procedures to ensure that a WS-X6K-S1A-MSFC2 is running the latest code on both the Supervisor 1 and the MSFC2 router feature card.

]]> Upgrade the Supervisor 1 (WS-X6K-SUP1A-2GE) to latest code.

Step 1: Assign an IP address to SC0 (Fibre) port on the supervisor engine.

set interface sc0 192.168.1.10 255.255.255.0
set interface sco up

Step 2: Copy software image from a TFTP server.

Console> (enable) copy tftp flash
IP address or name of remote host [192.168.1.30]?
Name of file to copy from [cat6000-supk8.7-6-14.bin]?
Flash device [bootflash]?
Name of file to copy to [cat6000-supk8.7-6-14.bin]?
15990656 bytes available on device bootflash, proceed (y/n) [n]? y

Note: You may need to format the bootflash using "format bootflash" before you copy the new image from your TFTP server.

Step 3: Clear and assign the new image to the boot variable.

clear boot system all
set boot sys flash bootflash:cat6000-supk8.7-6-14.bin prepend

Step 4: Reset the switch to allow the new software version to load.

reset

Upgrade the MSFC2 to latest code. (Done after you upgrade the OS on the Supervisor Engine as detailed above.)

Step 1: After the switch reloads, switch to the console port on the MSFC2.

switch console

Step 2: Assign an IP address to the MSFC2 for upgrading from a TFTP server.

conf terminal
int vlan 1
ip address 192.168.1.10 255.255.255.0
no shutdown
exit
exit

Step 3: Ping your TFTP server to make sure you have connectivity.

ping 192.168.1.30

Step 4: If ping is ok, copy from TFTP to flash. The MSFC2 carries two separate images, one is a boot helper image and the other is the system image. The following will copy both images.

copy tftp flash
Address or name of remote host [192.168.1.30]?
Source filename [c6msfc2-boot-mz.121-26.E3.bin]?
Destination filename [flash]? c6msfc2-boot-mz.121-26.E3.bin

copy tftp flash
Address or name of remote host [192.168.1.30]?
Source filename [c6msfc2-boot-mz.121-26.E3.bin]? c6msfc2-jsv-mz.121-26.E3.bin
Destination filename [flash]? c6msfc2-jsv-mz.121-26.E3.bin

Note: You may need to format your bootflash before you can copy the new boot and system image from your TFTP server.

Note 2: The bootflash must be large enough to accomodate both images. Default bootflash modules are 16MB, you may need to upgrade the bootflash to 32MB for newer images.

Step 5: Change boot variable to load the new boot loader and system image.

conf terminal
boot bootldr bootflash:c6msfc2-boot-mz.121-26.E3.bin
boot sys flash bootflash:c6msfc2-jsv-mz.121-26.E3.bin
exit
write memory

Step 6: Reload MSFC2 and switch back to Supervisor Engine Console

reload
CTRL C+C+C

How do I switch console between a Catalyst 6500 Supervisor Engine and an MSFC or MSFC2?

A Supervisor engine on a Cisco Catalyst 6500 Series can run router software if an MSFC or MSFC2 feature card is installed. Each card (the supervisor and msfc card) have their own console port used to configure each card.

]]> The MSFC / MSFC2 cards however do not have an external console port for you to plug into and configure. Console access is made through the same console port that is on the Supervisor engine. To switch to the console port on an MSFC or MSFC2 you need to issue the "switch console" command from the Supervisor engine prompt. This will switch the console to the MSFC / MSFC2. To get back to the supervisor engine console you will need to type "CTRL C C C" (that is CTRL KEY + C - 3 times).

How do I set the system boot variable on a Catalyst 6500 Switch?

If you upgraded or modified the software on a Cisco Catalyst 6500 series switch or more specifically a Sup1 or Sup2 supervisor engine, you need to modify the system boot variable.

]]> The system boot variable determines where the supervisor engine should boot from. If you upgrade the software, your system boot variable is most likely still set to boot from the old software image. To change the boot system variable perform the following:

Issue the following command:

set boot sys flash bootflash:cat6000-supk8.7-6-14.bin prepend

You will want to replace "cat6000-supk8.7-6-14.bin" above with the actual file name that you loaded on the switch.

Now if you reset the switch it should boot from the bootflash:cat6000-supk8.7-6-14.bin image.
