Releases 2 - 5.2, Part Number OL-4545-01, Rev. H0, May 2006
Chapter 5 Installing the Cisco MGX Switch or Gateway
Installing the MGX 8850 (PXM1E/PXM45) Switch, MGX 8850/B or MGX 8880 Media Gateway
Note Tighten the top and bottom captive screws in increments to prevent misalignment of the card.
Do not overtighten the screws, but tighten them enough to secure the card.
Step 8 Repeat Step 2 through Step 7 for each back card that you are reinstalling in the chassis.
Step 9 Install blank faceplates over any empty slots.
Reinstall the Front Cards
Note All cards must be fully seated in the chassis. When installing the front 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.
Each single-height front card has an extractor lever at the top of the faceplate to secure it in the card cage.
Each double-height front card has an extractor lever at both the top and the bottom of the faceplate.
Caution If the AXSM-1-2488 or AXSM-1-2488/B front cards are installed with incorrect back cards, damage to
the cards might result.
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 chassis.
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 reinstall a front card in the 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 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 1-43and Figure 1-44 for the MGX 8880.
Step 2 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.
Step 3 Verify that the extractor lever(s) are in the unlatched position.
