b. With the left and right levers rotated out perpendicular to the face of the
controller, slide the back of the controller into the appropriate slot.
c. Push on both sides of the controller so that it slides into the slot evenly.
Stop inserting the controller when it is about 1 inch from being fully inserted
into the slot. With the controller not fully inserted in the slot, attach all the
SFPs and cables that you disconnected from the failed controller in step 7
on page 146.
1) Replace the SFPs into the appropriate ports. See "Installing SFP
modules" on page 48.
2) Reconnect all cables, including all host and drive channel cables and
secondary cables (such as Ethernet connections).
d. Holding both levers, slowly push the controller until the notches in both the
left and right levers are aligned with the pins on the DS4800 enclosure so
that the controller is pulled evenly into the DS4800 storage subsystem
chassis, ensuring full electrical connection contact on all interface pins.
Attention: Verify that the controller does not snag any other DS4800
cables when you slide it into the controller bay.
e. Press the controller fully into the slot, engaging the pins on the enclosure.
f. 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.
12. Wrap the strain-relief clamp around the power cord approximately 20 cm (8 in.)
from the controller connection end. Leave some slack between the clamp and
the controller end of the power cord. Replace the strain-relief nut and tighten it
securely to secure the clamp to the controller unit.
13. Connect the power cord to the new DS4800 controller AC power connector.
Plug the power cord into a properly grounded electrical outlet.
14. Wait up to 5 minutes for the DS4000 Storage Manager client software to
recognize the new controller.
15. Complete any remaining Recovery Guru procedures for controller replacement,
if needed.
16. Check the LEDs on the new controller to verify that the controller is fully
operational. See "RAID controller LEDs" on page 120.
17. Remove the antistatic protection.
18. Use the DS4000 Storage Manager client Subsystem Management window to
check the status of all components in the storage subsystem.
v If the new controller is online and the DS4000 Storage Manager client
Subsystem Management window indicates normal operation, go to step 21
on page 150.
v If the new controller is online and the DS4000 Storage Manager client
Subsystem Management window indicates a problem status, go to
"Troubleshooting the storage subsystem" on page 117.
v If the new controller is offline, go to step 19.
19. If the newly inserted controller is in an offline state, see the DS4000 Storage
Manager client online help for instructions on bringing the controller online.
If necessary, open the DS4000 Storage Manager Subsystem Management
window and place the controller online; select the offline controller and click
Advanced Recovery
20. Verify the state of the LEDs on the newly inserted controller. See "RAID
controller LEDs" on page 120. You can also use the DS4800 Storage Manager
Place controller online.
