Chapter 8 Switch Maintenance Procedures
Adding Cards
When adding a standby PXM45 card to your switch, you need to physically install the PXM45 card and
the back cards in the following order:
1. PXM Hard Drive card (PXM-HD)
2. PXM45-UI-S3 card
3. PXM45 front card
After the new standby PXM45 front and back cards are installed, the active PXM45 card will initialize
the standby card set. The initialization procedure takes some time. You can verify that initialization is
complete by entering the dspcd command with the standby slot number, for example, dspcd 8. If the
front card state is “Standby,” initialization is complete.
Adding AXSM Cards
When you add an AXSM card to a switch, you are adding new front and back cards to a slot that is not
configured for an AXSM card. The following procedure describes how to add AXSM cards to
unconfigured slots.
Note If the slot has been previously configured for an AXSM 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 AXSM card that previously
operated in this switch, see “Replacing AXSM Cards,” which appears later in this chapter. For
instructions on decommissioning a slot, see the “Decommissioning an AXSM 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 ASXM 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.
After the new AXSM front and back cards are installed, the Fail LED on the front card flashes and none
of the LEDs on the back cards are lit. If you enter the dspcds command, the card state in the display
appears as Failed.
Step 3 To initialize the slot for the AXSM card, enter the following command:
mgx8850a.7.PXM.a > setrev <slot> <revision>
Replace <slot> with the card slot number for the new AXSM card. Replace <revision> with the software
version number for the runtime firmware the card will use. You can find the software version number in
the Release Notes for Cisco MGX 8850 and MGX 8830 Software Version 3 (PXM45/B and PXM1E) or
the Release Notes for Cisco MGX 8950 Software Version 3. To determine the version number from the
runtime firmware filename, see “Determining the Software Version Number from Filenames,” which
appears in Chapter 7, “Switch Operating Procedures.”
