Replacing the fuse
CAUTION: Ensure that the power supply module has been disconnected from the external power source
and the module’s ON/OFF switch has been set to “
0
”.
Failure to observe this caution could result in damage to, or failure of the power supply module.
Note
: The CPSMP-205 power supply module may be “hot swapped” (i.e., serviced while the chassis is in
operation) provided the module to be serviced has been disconnected from its external power supply and

0
” - Off.

3. From the inside edge of the power receptacle, insert a small flat blade screwdriver into the groove
on the front, inside edge of the fuse holder and carefully pry the fuse holder from the power
supply module. See Figure 11 below.
