Figure 2 Installing a card (MPU)
Installing a subcard
CAUTION:
To ensure good ventilation, install filler panels in unused slots.
This section describes how to install a subcard on a base card. The base card installation procedure
is the same as the card installation procedure (see "
Installing MPUs/service modules ").
The subcards are hot swappable.
To install a subcard:
1. Wear an ESD wrist strap, and make sure it has a good skin contact and is reliably grounded.
For more information, see "
Attaching an ESD wrist strap ."
2. Make sure the base card is installed in the router.
3. Unpack the subcard.
4. Install the subcard in the base card:
a. Remove the filler panel (if any) from the target slot on the base card, as shown by callout 1
in
Figure 3 .
Keep the removed filler panel secure for future use.
b. Open the ejector levers on the subcard, as shown by callout 2 in Figure 3 .
c. Gently push the subcard (with bottom up) into the slot along the guide rails until the ejector
levers of the subcard touch the base card panel, as shown by callout 3 in
Figure 3 .
d. Push the front panel of the subcard forward. Then close the ejector levers so that the
subcard is flush with the base card, as shown by callout 4 in
Figure 3 .
e. Use a Phillips screwdriver to fasten the screws on the subcard, as shown by callout 5 in
Figure 3 .
