Replacing Cold Swappable FRUs

69

Note –

You can also use the Power ON/OFF button on the front of the server to

initiate a graceful system shutdown. This button is recessed to
prevent accidental server power-off. Use the tip of a pen to operate this button.

Refer to the

Sun Fire T2000 Server Advanced Lights Out Management (ALOM) Guide

for

more information about the ALOM poweroff command.

To Extend the Server to the Maintenance
Position

If the server is installed in a rack with the extendable slide rails that were supplied
with it, use this procedure to extend the server to the maintenance position.

Note –

Removing the server from the rack is recommended for all cold-swappable

FRU replacement procedures except the DIMMs, PCI cards, and the system
controller.

1. (Optional) Issue the following command from the ALOM sc> prompt to locate the

system that requires maintenance.

Once you have located the server, press the Locator LED button to turn it off.

2. Check to see that no cables will be damaged or interfere when the server is

extended.

Although the cable management arm (CMA) that is supplied with the server is
hinged to accommodate extending the server, you should make sure that all cables
and cords are capable of extending.

3. From the front of the server, release the slide rail latches on each side.

Pinch the green latches as shown in

FIGURE 4-1
