Scenario 3: Installing a Remote Unit on a Wall
Context
This installation method applies to the S5731-L (except the S5731-L4P2HW-RUA and S5731-L16P2SR-RUA) and S5731S-L (except the S5731S-L4P2HW-RUA and S5731S-L16P2SR-RUA).
Before drilling holes on a wall, make sure that no power cable is routed in the wall. Otherwise, power cables in the wall may cause personal injury.
- Do not stack the horizontally placed remote units.
- Do not install the remote unit outdoors. Remote units can only be installed indoors.
- It is recommended that power adapters and optical fibers not be vertically installed above remote units.
- Use standard power adapters provided by Huawei to supply power to remote units. Otherwise, the remote units may not work properly or security risks may be introduced.
- Ensure that remote units are horizontally installed on a wall, with ports facing downwards.

Tools and Accessories
- Hammer drill
- Phillips screwdriver
- Wall anchors and mounting screws (two for each remote unit, separately purchased)
Procedure
- Measure the distance between the two mounting holes on the rear panel of the remote unit.
- Use a measuring tape to determine positions of two mounting holes, keep the two positions aligned, and mark the positions with a marker. Ensure that the distance between the two mounting holes is the same as that of the two holes on the remote unit.
- Drill holes and install mounting screws.
- Choose an appropriate drill bit according to the diameter of the mounting screws.
- Hammer the hollow wall anchors into the mounting holes.
- Use a Phillips screwdriver to screw the mounting screws into the wall anchors. Leave the screws protruding 10 mm from the wall.
It is recommended that cap screws meeting the following requirements be used:
- Diameter of the shank: ≤ 4 mm
- Height of the shank: ≥ 25 mm
- Diameter of the head: 6 to 8 mm
- Height of the head: ≤ 2 mm
- Align the mounting holes on the rear of the remote unit with mounting screws and hang the remote unit on the mounting screws.Figure 2-17 Mounting a remote unit on a wallFigure 2-18 Remote unit mounted on a wall
