Removing and Installing the Double-Height Front Cards
Caution When extracting a front card, keep the card level until it is completely extracted from the chassis. Do not
allow the front cards to drop against the cards below them. This could damage components on the cards.
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 142
Remove the Double-Height Front Cards
A card is seated firmly in a chassis by inserting the card and closing the levers at the top and bottom.
Use the following steps to remove double-height front cards from the chassis.
How Most Card Levers Work
Step 1 Open the front door of the chassis, if a door is present.
Step 2 Connect a grounding strap to the ESD grounding jack or to the equipment rack.
Step 3 Press the flat-head tip of the 3-in-1 tool into the slot of the extractor lever until the lever springs open
(see Figure 6-3).
• In an MGX 8830 switch, cards are installed horizontally, so the slots are at the left and right sides
of the card, as opposed to top and bottom.
• Each double-height front card has an extractor lever at the top and bottom.
Step 4 Pull the extractor levers to disconnect the front card from the midplane.
Step 5 Gently pull the front card out of the card cage, keeping the card level so that it does not contact the card
below it.
How VXSM Card Levers Work
The VXSM front cards use a dual lever system. To install a VXSM card:
Step 1 Hold up the metal lever at the top of the card.
