13. Find the label on the top of the new or upgraded controller and record its
media access control (MAC) address.
14. Install the new or replacement controller by performing the following:
a. Carefully position the controller at the back of the storage subsystem
chassis. Ensure that the controller can slide into the storage subsystem
chassis without obstruction.
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 8
on page 172.
1) Replace the SFPs into the appropriate ports. See "Installing SFP
modules" on page 49.
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 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.
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.
15. 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.
16. Connect the power cord to the ac power connector of the controller you
replaced or upgraded. Plug the power cord into a properly grounded electrical
outlet.
17. Wait up to 5 minutes for the DS Storage Manager client software to recognize
the controller you replaced or upgraded.
18. Complete any remaining Recovery Guru procedures for controller replacement,
if needed.
19. Check the LEDs on the controller to verify that the controller is fully
operational. See "RAID controller LEDs" on page 145.
