Cisco MGX 8850 (PXM45) and MGX 8950 Software Configuration Guide
Release 3, Part Number 78-14788-01 Rev. C0, January 2004
Chapter 2 Configuring General Switch Features
Initializing the Switch
Step 5 If the switch does not display any messages or prompt, press Return.
When startup is complete for an uninitialized switch, it will display the PXM45 backup boot prompt:
pxm45bkup>
Step 6 Locate and write down the version number for the runtime firmware provided with your switch. You need
this version number to complete the next step.
The version number is listed in the Release Notes for Cisco MGX 8850 and MGX 8830 Software
Version 3 (PXM45/B and PXM1E) and the Release Notes for Cisco MGX 8950 Software Release 2.1.60,
and must be entered using the same format listed in the firmware file name. For example, if the firmware
filename is pxm45_002.001.060.000_mgx.fw, the firmware version number you will enter is
002.001.060.000.
Step 7 When the PXM45 backup boot prompt appears, define the PXM45 runtime firmware version by entering
the sysVersionSet command as follows:
pxm45bkup> sysVersionSet version
Replace version with the version number for the runtime firmware. For example,
pxm45bkup> sysVersionSet 002.000.001.000
Step 8 Reboot the switch by entering the reboot command as follows:
pxm45bkup> reboot
During initialization, the switch will appear to boot twice. When the reboot is complete, the switch
displays the Login prompt, which indicates that the firmware is loaded and the switch is ready for
configuration.
Tip The sysVersionSet command has failed if the switch reboot process stops and displays the
message “
Can not open file C:/version” or the message “Unable to determine size of
C:/FW/filename
.” If this happens, press Return to display the backup boot prompt, then see the
“Troubleshooting Upgrade Problems” section in Appendix A, “Downloading and Installing
Software Upgrades.”
Step 9 To log in to the switch, enter the login name cisco, then enter the password cisco. For example:
Login: cisco
password:
unknown.7.PXM.a >
Note The default configured username and password sets are: user cisco, password cisco; user service,
password serviceuser; and user superuser, password superuser.
Note If the switch has not fully started and is operating in init state (which is also called stage 1 CLI
mode), an i appears in the switch prompt: unknown.7.PXM45.i>
. In this mode, you can only
log in with the user ID and password supplied with the switch, and a limited set of commands
are available for troubleshooting. If you log in during init state and the card progresses to the
active or standby state, the card will log out the init state user and prompt you to log in again.
At this point, you can log in as a configured user with the corresponding password.
