8. Insert a nonconducting stylus through the appropriate hole in the cover of the
controller and press down gently. Figure 102 shows the location of the circuit
breaker access hole in the controller B cover.
Note:
When controllers A and B are inserted in the controller slots, the
location of the circuit breaker access hole is as follows. On controller A,
the circuit breaker access hole is located on the left side on the bottom
of the controller. On controller B, the circuit breaker access hole is
located on the right side on the top of the controller (as shown in
Figure 102).
9. Reset the circuit breaker that tripped by pressing down with the stylus on the
rocker switch.
10. Slide the controller into the storage subsystem chassis.
a. Holding both levers, slowly push the controller until the notches in both the
left and right levers are aligned with the pins on the DS5100 and DS5300
enclosure so that the controller is pulled evenly into the DS5100 and
DS5300 chassis, ensuring full electrical connection contact on all interface
pins.
Attention:
Verify that the controller does not snag any other DS5100 and
DS5300 cables when you slide it into the controller bay.
b. Press the controller fully into the slot, engaging the pins on the enclosure.
c. Hold open both latches and push both left and right levers simultaneously
to the closed position. Release the latches. When you release the latches,
you should hear both latches snap over the levers, indicating that the
component is locked in place.
11. If you removed the interface cables, reconnect all host interface cables and
drive interface cables, including the SFP modules.
12. Wait up to 5 minutes for the DS Storage Manager client software to recognize
the controller.
13. Complete any remaining Recovery Guru procedures for controller replacement,
if needed.
14. Based on the Host Channel Speed, Drive Channel Speed, and Needs
Attention LED status, proceed to one of the following steps:
