Installing a card
The cards on the switch include MPUs, LPUs, and switching fabric modules, which can be installed in
horizontal or vertical slots.
•
Horizontal slot—with the PCB board on the card facing up
•
Vertical slot—with the PCB board on the card facing left
All the cards are hot swappable, and the installation procedures are similar. The following takes a card
installed in a horizontal slot as an example.
To install a card:
1.
Before installing a card to the chassis, make sure that the connectors on the card are not broken or
blocked in order to avoid damaging the backplane.
2.
Wear an ESD-preventive wrist strap, and make sure it makes good skin contact and is well
grounded. For more information, see “
Attaching an ESD-preventive wrist strap
.”
3.
As shown in callout 1 on
Figure 17
, remove the blank panel (if any) from the slot to be used. Keep
the blank panel for future use.
4.
As shown in callout 2 on
Figure 17
, 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.
5.
When most part of the card is inserted in the slot, press the ejector levers on the card outward.
6.
Push the card until the positioning pin on card touches the hole on the chassis.
7.
As shown in callout 3 on
Figure 17
, press the ejector levers inward until the ejector levers touch the
panel tightly and the card seats into the backplane
