Installing MPUs/LPUs
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 a good skin contact and is well grounded. For more
information, see "
Attaching an ESD wrist strap ."
2. As shown in callout 1 on Figure 20 , remove the blank filler (if any) from the slot to be used. Keep
the blank filler secure for future use.
3. As shown in callout 2 on Figure 20 , 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.
4. As shown in callout 3 on Figure 20 , when most part of the card 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 20 , press 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 20 , fasten the captive screws on the card.
8. When the switch is powered on, verify the running status of the card.
You can verify the running status of a card by referring to the card status LED (SLOT) on the SRPU of the
switch. If the RUN LED blinks, 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 verify the card running status at the command line interface (CLI).
For more information, see " Hardware management and maintenance ."
