Chapter 8 Switch Maintenance Procedures
Replacing Cards with the Same Card Type
Adding RPM Cards
When you add an RPM card to a switch, you are adding new front and back cards to a slot that is not
configured for an RPM card. The following procedure describes how to add RPM cards to unconfigured
slots.
Note If the slot has been configured previously for an RPM card, you can either replace that card with a card
of the same type or you can decommission the slot. If you are replacing an RPM card that previously
operated in this switch, see the “Replacing RPM Cards” section later in this chapter. For instructions on
decommissioning a slot, see the “Decommissioning an RPM Slot” section later in this chapter.
Step 1 Before installing the hardware, enter the dspcd command to verify that the slot in which you want to add
the card has not been configured. In the following example, the dspcd report shows that slot 14 is not
configured.
pop20one.7.PXM.a > dspcd 14
ERR: The slot specified, has no card configured in it.
ERR: Syntax: dspcd ["slot_number"]
slot number -- optional;
Step 2 Install the RPM card and the appropriate back cards in an unconfigured slot as described in the
Cisco MGX 8850 Hardware Installation Guide (PXM45/B and PXM1E) or the Cisco MGX 8950
Hardware Installation Guide.
Step 3 Initialize the RPM card as described in the “Initializing RPM-PR Cards” section in Chapter 5,
“Preparing RPM-PR Cards for Operation.”
Step 4 Verify the RPM software version level as described in the “Verifying the Software Version in Use”
section in Chapter 5, “Preparing RPM-PR Cards for Operation.”
Step 5 Establish card redundancy as described in the “Establishing Redundancy Between Two RPM-PR Cards”
section in Chapter 5, “Preparing RPM-PR Cards for Operation.”
Step 6 Configure RPM communications as described in the Cisco MGX 8850 Route Processor Module
Installation and Configuration Guide.
Replacing Cards with the Same Card Type
This section describes how to replace cards with another card of the same type. The following sections
describe how to replace the following types of cards:
• PXM45 cards
• AXSM cards
• RPM cards
Note For information on replacing a card with a newer hardware version, see the “Upgrading Cards” section
later in this chapter.
