Cisco MGX 8950 Hardware Installation Guide
Release 3, Part Number 78-14147-02 Rev. A0, November 2002
Chapter 3 Installing a Cisco MGX 8950
Installation Procedures
Reinstall the Back Cards
Note All cards must be fully seated in the switch. When installing the back card, apply even pressure to the
top and bottom of the faceplate to make sure that the card is fully seated.
The card should slide in and out with only slight friction on the adjacent board’s EMI gaskets. Do not
force the card. Investigate any binding.
Caution To prevent damage to components on the bottom side of a card, support the faceplate and keep the card
level while sliding it into the switch.
Caution Cards must be inserted in the correct slot positions. If service module back cards are installed in the
wrong slots, electrical damage can occur. If a service module back card is inserted into a PXM back card
slot, damage to the card and backplane can result. If the AXSM-1-2488 or AXSM-1-2488/B front cards
are installed with incorrect back cards, you may damage the cards.
Caution If you accidentally attempt to insert a service module back card into a PXM back card slot and then have
difficulty operating the switch, examine the backplane pins and back card connector to see if they have
been bent or damaged.
Caution Do not use a power screwdriver on captive screws.
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place.
Complete the following steps to reinstall a back card into the Cisco MGX 8950 switch:
Step 1 Refer to the notes you made when you recorded the location of each card to ensure that the cards are
installed in the correct slots. For slot assignments for your system, refer to the
“Cisco MGX 8950 Switch
Compartment” section on page 1-3.
Step 2 See the “Card Installation Guidelines” section on page 2-9 to verify that there are no bent pins, bent
dividers, or damaged connectors on the back cards.
Step 3 Verify that the two extractor levers on the back card are in the latched position (parallel with
the
faceplate).
Step 4 Position the back card over the appropriate slot guides and align the back card edge with the slot guides
(top and bottom) in the switch.
Step 5 Gently apply even pressure to the top and bottom of the faceplate while pushing the back card into
the
slot.
