Installing FRUs
This section describes the installation procedures for the MPUs, LPUs, fan trays, and power
modules. For the compatibility matrix between these modules and the switch models, see
H3C
S12500X-AF Switch Series Installation Guide
.
WARNING!
Long-time exposure to strong air flow might cause discomfort. As a best practice, do not stand
close to the air outlet vents while the switch is operating. If you must be next to the switch on the air
outlet vent side for an extended period, avoid the air flow or take other protective measures.
CAUTION:
For good ventilation of the switch, install filler panels in the empty card and power module slots.
Attaching an ESD wrist strap
To prevent electronic components from ESD damage, wear an ESD wrist strap and make sure it
makes good skin contact and is reliably grounded before you install FRUs. See
attaching an ESD wrist strap.
Installing and removing MPUs
CAUTION:
•
If you are not to install an MPU in an MPU slot, keep the filler panel in the slot.
•
When you install an MPU, avoid damaging the connectors on the MPU.
You can install one MPU, or two MPUs for redundancy on the switch. If you are to install one MPU,
install it in either of the MPU slots.
Installing an MPU
1.
As shown by callout 1 in
, remove the filler panel from the target MPU slot.
Keep the removed filler panel secure for future use.
2.
As shown by callout 2 in
, press the latch on the MPU to release the ejector lever.
Rotate outward the ejector lever to the outmost.
3.
As shown by callout 3 in
, orient the MPU with the upside up. Hold the MPU by the
front panel with one hand and support the bottom with the other. Push the MPU steadily into
the slot along the guide rails until it has firm contact with the slot.
Keep the MPU parallel to the slot to avoid touching other components in the chassis.
4.
As shown by callout 4 in
, rotate inward the ejector lever until the latch locks the
ejector lever in place.
