Replacing an RTC Battery Inside the Server Node
The battery type inside the server node is CR2032.
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.
Note
You do not have to remove the server node cover to access the RTC battery.
Step 3
Remove the server node RTC battery:
a. Locate the RTC battery. See Figure 3-25 .
b.
Bend the battery retaining clip away from the battery and pull the battery from the socket.
Step 4
Install the RTC battery:
a.
Bend the retaining clip away from the battery socket and insert the battery in the socket.
Note
The flat, positive side of the battery marked “+” should face the retaining clip.
b.
Push the battery into the socket until it is fully seated and the retaining clip clicks over the top of
the battery.
Step 5 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 6
Replace power cords and then power on the system by pressing and holding the power button on the front
handle for four seconds.
