Switch Maintenance Procedures
This chapter describes the configuration changes that are needed after a switch has been initialized,
started, and configured, and you want to do any of the following tasks:
• Add cards
• Replace cards
• Upgrade cards
• Decommission an AXSM slot
• Decommission an RPM slot
AXSM and RPM slots must be decommissioned when you want to change the type of card that runs in
the slot.
Adding Cards
After the initial installation and configuration of an Cisco MGX 8850 or Cisco MGX 8950 switch, you
can add additional cards to empty slots in the chassis. When you add a card, as opposed to replacing a
card, you must configure the switch to recognize the new card. The following sections describe how to
configure the switch to recognize new PXM45 cards and AXSM cards.
Adding a Standby PXM45 Card
During installation, single or redundant PXM45 cards can be installed in the switch. The procedure for
initializing cards after installation is described in the “Initializing the Switch” section in Chapter 2,
“Configuring General Switch Features.”
When you add a PXM45 card to the switch, you are adding a standby PXM45 card to a switch with a
single active PXM45 card.
Note If you are replacing a PXM45 card that previously operated as either an active or standby card in this
switch, see the “Replacing Cards with the Same Card Type” section, later in this chapter.
