Instructions for “Copying Software Files to the Switch” are in Appendix A of the Ci sco MGX 8800/8900
Series Configuration Guide, Release 5.2 at
http://www.cisco.com/univercd/cc/td/doc/product/wanbu/8850px45/rel5/scg/mgx5scg.pdf. The
Configuration Guide also describes how to connect to the console port and initialize the switch.
Step8 Insert the standby PXM back cards, then the front card. Attach the console port cable to the back card.
Step9 Through the console port connection, monitor the standby PXM card as it comes up to Standby mode.
When the card is in Standby mode, the prompt will appear like n.8.PXM.s>.
•If the standby PXM card comes up in backup boot, you might need to load software onto the PXM
card before proceeding.
•Check for alarms on the Standby PXM card from the Active PXM card. Use the display cards
(dspcds) command to ensure that the Active PXM card has no alarms (Alarms = none). Also check
that the Standby PXM card has no alarms.
Step10 Put in the back cards (if any) for the Service Resource Modules (SRMs) for the primary PXM card. Then
insert the SRM front card, one at a time. See if the SRM comes up. The green light comes on when it’s
active and functional. Check that there are no alarms as each card goes through the hardware check, loads
firmware, and so on.
Step11 Repeat Step 10 for th e SRMs for the secondary PXM.
Note Refer to Tabl e 5-9 for the proper slots in which to insert SRM cards.
Step12 Install the remaining front and back cards, one card set at a time. Check operation at the console port for
each card, using display commands. As you install each card set, verify that it has come up properly.
