Installing MPUs/LPUs/switching fabric modules

IMPORTANT:

Before installing a card to 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 over an empty MPU, LPU, or switching fabric

•

module slot. MPU slots use the same type of blank filler panels as LPU slots.

The installation procedures for MPUs, LPUs, and switching fabric modules are the same. Unless otherwise

stated, MPUs, LPUs, 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 uses a horizontally oriented card as an example.

To install a horizontally oriented card:

Wear an ESD wrist strap, and make sure it has a good skin contact and is well grounded. For more

information, see

As shown in callout 1 on

the blank panel for future use.
