Installing MPUs/interface modules
CAUTION:
•
To avoid damages to the backplane, make sure the module connector is not broken or blocked
before inserting the module into the chassis.
•
When installing a module, make sure its PCB side faces upward.
•
For adequate cooling and ventilation, install a filler panel in each unused slots. MPUs and
interface module slots can use the same type of filler panel.
The installation procedure is the same for MPUs and interface modules. The following procedure
uses an MPU as an example.
To install an MPU:
1. Wear an ESD wrist strap, and make sure it makes good skin contact and is reliably grounded.
For more information, see "
Attaching an ESD wrist strap ."
2. Remove the filler panel (if any) from the target slot.
Keep the filler panel secure for future use.
Figure4-2 Removing the filler panel from the target MPU slot
3. As shown by callout 1 in Figure4-3 , open the ejector levers of the MPU.
4. As shown by callout 2 in Figure4-3 , insert the MPU into the slot along the guide rails until the
ejector levers engage the slot edges.
5. As shown by callout 3 in Figure4-3 , close the ejector levers so that the MPU front panel is flush
with the slot.
6. As shown by callout 4 in Figure4-3 , fasten the captive screws on the MPU.
