Installing a card
All the MPUs and LPUs for the switch series are hot swappable. 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.
To install a card:
1. Wear an ESD wrist strap, and make sure it makes good skin contact and is well grounded. For
more information, see "Attaching an ESD wrist strap."
2. As sh
own in callout 1 on Figure 18, rem
ove the blank filler (if any) from the slot to be used. Keep
the blank filler correctly for future use.
3. As shown in callout 2 on Figure 18, hold the c
ard 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.
4. As shown in callout 3 on Figure 18, when most part of the c
ard is inserted in the slot, press the
ejector levers on the card outward.
5. Push the card until the positioning pin on card touches the hole on the chassis.
6. As shown in callout 4 on Figure 18, pres
s the ejector levers inward until the ejector levers touch the
panel tightly and the card seats into the backplane.
7. As shown in callout 5 on Figure 18, fasten the c
aptive screws on the card.
8. When the switch is powered on, examine the running status of the card.
You can examine the running status of a card by referring to the card status LED (SLOT) on the MPU
of the switch. If the RUN LED flashes, the card in the slot operates correctly. For more information
about card status LED (SLOT), see "Appendix C LEDs."
After the switch is powered on, you
can examine the card running status at the command line
interface (CLI). For more information, see "Hardware management and maintenance."
