Maintenance
If you are performing on-site hardware maintenance, first remove the control
unit housing (the cover of the control unit), then disconnect the AC power.
Removing the Control Unit Housing
To remove the control unit’s housing, see Figure 1-5.
■ If you have a MERLIN II

Communications System or a MERLIN
LEGEND Communications System (Release 2.1 or later):
1. Pull the bottom front of the housing towards you. When it
releases, remove it by lifting up as shown in Figure 1-5
.
2. Remove the top cover from each carrier by pushing it straight up
from the front.
■ If you have a MERLIN LEGEND Communications System (Release 2.0
or earlier):
1. Pry the clips from the housing on both sides of the control unit;
use a screwdriver if they are difficult to remove.
2. Carefully pull the housing towards you.
NOTE:
If the MERLIN LEGEND (Release 2.0 or earlier) system has more than
one carrier, make sure you hold the housing assembly on the basic carrier
at the sides; otherwise, the housing may disassemble as the front and
side panels are only slotted together.
