Installing a card
IMPORTANT:
•
Before installing a card in the chassis, make sure the connectors on the card are not broken or blocked
to avoid damaging the backplane.
• To ensure good ventilation, install a blank filler panel in an empty slot.
• Before you install a card that has a protection box, remove the protection box from the card as follows:
a. Loosen the captive screws that secure the card to the protection box.
b. Pull the ejector levers of the card outwards.
c. Pull the card out of the protection box.
The installation procedures for MPUs, LPUs, base cards, and switching fabric modules are similar. Unless
otherwise stated, MPUs, LPUs, base cards, and switching fabric modules are collectively referred to as
"cards" in this document.
These cards are either horizontally oriented or vertically oriented. When installing a card in a horizontal
slot, make sure its PCB faces up. When installing a card in a vertical slot, make sure its PCB faces left.
This section takes installing a horizontally oriented card as example.
To install a horizontally oriented card:
1. Wear an ESD wrist strap, and make sure it makes good skin contact and is reliably grounded. For
more information, see "
Attaching an ESD wrist strap ."
2. Remove the blank filler panel (if any) from the slot. Keep the blank filler panel for future use.
3. Rotate down the ejector levers on the card.
Skip this step if the card is not a base card.

4. Rotate outward the two ejector levers on the card.
5. Hold the card by the front panel with one hand and support the card bottom with the other. Slide
the card steadily into the slot along the guide rails until you cannot push the card further. Do not
touch the components on the card.
6. Rotate inward the ejector levers until the card come in close contact with the backplane.
7. Rotate up the ejector levers.
Skip this step if the card is not a base card.
