Installing MPUs/LPUs
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 and LPUs are the same. Unless otherwise stated, MPUs and LPUs
are collectively referred to as "cards" in this document.
These cards are hot swappable.
To install a card:
1. Wear an ESD wrist strap, and make sure it has good skin contact and is reliably grounded. For
more information, see "
Attaching an ESD wrist strap ."
2. Remove the blank filler (if any) from the slot to be used. Keep the blank filler secure for future use.
3. Rotate out the ejector levers on the card.
4. Hold the card by the front panel with one hand and support the card bottom with the other (do not
touch its circuit). Slide the card steadily into the slot along the guide rails until you cannot push the
card further.
5. Rotate in the ejector levers on the card.
6. Fasten the captive screws on the card.
