v Yes – A power supply and fan unit has failed. To replace the failed power
supply and fan unit, see "Replacing a power supply and fan unit" on page
183.
v No – Go to step 6 on page 161.
Attention: Fiber-optic cables are fragile. Bending, twisting, folding, or
pinching fiber optic cables can cause damage to the cables, degraded
performance, or data loss. To prevent damage, do not twist, fold, pinch, or step
on the cables. Do not bend the cables in less than a 2-inch radius.
Note: You do not need to remove the interface cables from the controllers to
reset the circuit breakers; however, it is best practice to remove the
cables to make this procedure easier. If you choose to remove the
interface cables, ensure that you label each cable so that you can
reconnect them correctly to the controller. Figure 99 and Figure 100 on
page 161 identify all of the connectors on the back of the controller.
