Chapter5 Installing the Cisco MGX Switch or Gateway
Installing the MGX 8850 (PXM1E/PXM45) Switch, MGX 8850/B or MGX 8880 Media Gateway
Caution To prevent damage to components on either side of a card, support the faceplate and keep the card level
while sliding it into the chassis.
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 int o a PXM back card
slot, damage to the card and backplane can result. If the AXSM-1-248 8 or AXSM-1-2488/B front cards
are installed with incorrect back cards, damage to the cards might result.
Caution If you accidentally attempt to insert a service modul e back card into a PXM back card slot and then have
difficulty operating the chassis, 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.
Statement 1029
Complete the following steps to reinsta ll a back card in the switch:
Step1 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 Table 1 -3 and:
•Figure 1-5 and Figure 1-6 for the MGX 8850 (PXM1E)
•Figure 1-7 and Figure 1-8 for the MGX 8850 (PXM45)
•Figure 1-43 and Figure 1-44 for the MGX 8880.
Step2 See the “General Card Installation Guidelines” section on page 3- 8 to verify that there are no bent pins,
bent dividers, or damaged connectors on the back cards.
Step3 Verify that the two extractor levers on the back card are in the latched position (parallel with
the faceplate).
Step4 Position the back card over the appropriate slot guides and align the back card edge with the slot guides
(top and bottom) in the chassis.
Step5 Gently apply even pressure to the top and bottom of the faceplat e while pushing the back card into
the slot.
Step6 Once the back card is installed in the chassis, apply even pressure to the top and bottom of the faceplate
to fully seat the back card.
Step7 Use the flat-head or Phillips tip of the 3-in-1 tool to tighten the two captive screws on the back
card faceplate.
