Replacing a RAID Controller Card Inside the Server Node
The Cisco modular RAID controller card connects to a mezzanine-style socket inside the server node.
The SuperCap power module (SCPM) comes already attached to a new card, so you do not have to
remove that separately.
Step 1 Shut down and remove power from the entire system, as described in Shutting Down and Powering Off
the System, page 3-9 .
Step 2
Remove a server node from the system:
a. Grasp the two ejector levers and pinch their latches to release the levers (see Figure 3-15 ).
b.
Rotate both levers to the outside at the same time to evenly disengage the server node from its
midplane connectors.
c. Pull the server node straight out from the system.
Step 3
Remove the server node cover as described in Removing the Server Node Cover, page 3-12 .
Step 4 Remove a Cisco modular RAID controller card:
a.
Loosen the two captive thumbscrews that secure the card to the board (see Figure 3-24 ).
b. Grasp the card at both ends and lift it evenly to disengage the connector on the underside of the card
from the mezzanine socket.
Step 5
Install a Cisco modular RAID controller card:
a. Align the card and bracket over the mezzanine socket and the three standoffs.
b.
Press down on both ends of the card to engage the connector on the underside of the card with the
mezzanine socket.
c. Install the screw that passes through the supercap power module (backup battery) cover.
Step 6
Install the heat sink assembly to the controller card:
a. Remove the protective tape from the thermal interface that is on the underside of the heatsink.
b.
Align the heat sink assembly and its two captive screws with the holes in the controller card.
c. Tighten the two captive screws to the two standoffs that are under the controller card.
Step 7
Replace the server node cover as described in Removing the Server Node Cover, page 3-12 .
Step 8 Install a server node:
a.
With the two ejector levers open, align the new server node with the empty bay.
Note
The server node must be in the top bay, as shown in Figure 1-2 on page 1-2 .
b.
Push the server node into the bay until it engages with the midplane connectors and is flush with the
chassis.
c. Rotate both ejector levers toward the center until they lay flat and their latches lock into the rear of
the server node.
Step 9
Replace power cords and then power on the system by pressing and holding the power button on the front
handle for four seconds.
Step 10 See Restoring RAID Configuration After Replacing a RAID Controller, page C-2 to restore your RAID
configuration.
