Installing MPUs/LPUs/switching fabric modules
IMPORTANT:
•
Before installing a card to 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 over an empty MPU, LPU, or switching fabric
module slot. MPU slots use the same type of blank filler panels as LPU slots.
• The switching fabric modules of the S10508, S10508-V, and S10512 have protection boxes when
shipped. Before you install a switching fabric module, pull the ejector levers on the module outwards,
and then pull it out of the protection box.
The installation procedures for MPUs, LPUs, and switching fabric modules are the same. Unless otherwise
stated, MPUs, LPUs, and switching fabric modules are collectively referred to as "cards" in this document.
These cards are either horizontally oriented or vertically oriented. When installing a card in a horizontal
slot, make sure its PCB faces up. When installing a card in a vertical slot, make sure its PCB faces left.
This section takes installing a horizontally oriented card as example.
To install a horizontally oriented 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 shown in callout 1 on Figure 19 , remove the blank filler panel from the slot. Keep the blank filler
panel for future use.
Some card slots do not have a blank filler panel. The figures in this section are for illustration only.
3. As shown in callout 2 on Figure 19 , 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.
4. 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 3 on Figure 19 , 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 4 on Figure 19 , fasten the captive screws on the card.
8. When the switch is powered on, check the running status of the card.
You can check the running status of a card by referring to the card status LED (SLOT) on the MPU
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 ."
