Prepare for Installation
Review the following guidelines before installation begins:
• Before removing any cards, modules, or assemblies, it is recommended that you carefully note and
write down their location or slot number in the chassis.
• Verify that your ESD grounding wrist strap is properly connected. See the “Preventing ESD
Damage” section on page 3-7 for detailed information about ESD procedures.
Remove the Front Cards
Complete the following steps to remove front cards from the chassis.
Note 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 Do not use a power screwdriver on captive screws.
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.
Step 1 Connect a grounding strap to the ESD grounding jack or to the equipment rack.
Step 2 Place the switch on a flat and stable surface (for example, the floor).
Step 3 Open the front door of the switch, as necessary.
Step 4 Record the location of all of the cards before you remove them.
Step 5 Insert and press the flat-head tip of the 3-in-1 tool into the slot(s) of the extractor lever(s) at the top (and
bottom) of the front card until the latch(es) springs open. Figure 5-12 shows the location of the lever slot
in relation to the top of the front card.
