Chapter5 Installing the Cisco MGX Switch or Gateway
Installing the MGX 8830 or MGX 8830/B Switch
Step9 Install blank faceplates over any empty slots.
Reinstall the DC PEM(s)
Complete the following steps to reinst all a DC PEM in the MGX 8830 switch:
Step1 Position the DC PEM edges over the appropriate guides at the left and right sides of the card cage.
Step2 Gently slide the DC PEM all the way into the slot and push to seat the DC PEM.
Step3 Use the flat-head or Phillips tip of the 3-in-1 tool to tighten the two captive screws located on the DC
PEM faceplate.
Note Tighten the right and left captive screws in increments to prevent misalignment of the card. Do
not overtighten the screws, but secure the card.
Step4 Verify that the DC PEM circuit breaker is OFF.
Step5 Repeat Step 1 and Step 4 for each DC PEM in the chassis.
Reinstall the Front Cards
Note All cards must be fully seated in the chassis. When installing the front card, apply even pressure to the
left and right 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 left of the faceplate to secure it in the card
cage. Each double-height front card has an extractor lever at both the left and right of the faceplate.
Caution To prevent damage to components on the bottom side of a card, support the facep late 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.
