Figure 4-10 Removing the metal sheet from an RRU installed in centralized mode
If an RRU is installed in centralized mode, the RRU can be removed without removing the two RRUs on
its right and left sides. The procedure is the same as that for removing a single RRU.
Step 6 Use an inner hexagon torque screwdriver to loosen captive screws on the attachment plate for
the RRU and on the top holes of the main bracket, as shown in Figure 4-11. Then raise the
bottom of the RRU to remove it, as shown in Figure 4-12.
