Installing FRUs

This section describes the installation procedures for the MPUs, service modules, fabric modules,
fan trays, and power modules. For the compatibility matrix between these modules and the device
models, see H3C S12500R Switch Router 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 device is operating. If you must be next to the device 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 device, install filler panels in empty FRU 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 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.
• To prevent a filler panel from being drawn into the chassis when fan speed is high, use both
hands to grasp the filler panel by its two sides during filler panel installation and removal on an
operating device.
You can install one MPU, or two MPUs for redundancy on the device. If you are to install one MPU,
install it in either of the MPU slots.

Installing MPUs for the S12516R and S12508R

For the S12516R and S12508R, the ejector levers of the MPUs and the ejector lever seats on the
MPU slots have pink marks. The MPU installation procedure is the same for the S12516R and
S12508R. The following procedure installs an MPU on an S12516R.
To install an MPU:
