Chapter 3 Maintaining the Server

Installing or Replacing Server Components

Replacing the Motherboard RTC Battery

Warning There is danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer’s instructions. [Statement 1015]

The real-time clock (RTC) battery retains system settings when the server is disconnected from power. The battery type is Panasonic CR2032 or equivalent.

To replace or install the motherboard CMOS battery, follow these steps:

Step 1 Remove the RTC battery (see Figure 3-18):

a.Power off the server as described in the “Shutting Down and Powering Off the Server” section on page 3-7.

b.Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.

Caution If you cannot safely view and access the component, remove the server from the rack.

c.Remove the top cover as described in “Removing and Replacing the Server Top Cover” section on page 3-8.

d.Locate the RTC battery. See Figure 3-18.

e.Gently remove the battery from the holder on the motherboard.

Step 2 Install an RTC battery:

a.Gently insert the battery into the holder and inside the retaining clip.

Note The positive side of the battery marked “3V+” should face the retaining clip and chassis wall.

b.Push the battery into the socket until it is fully seated.

c.Replace the top cover.

d.Replace the server in the rack, replace cables, and power on the server by pressing the Power button.
