Cisco Systems R2001120402, UCS C200 M1 manual Removing and Replacing the Server in a Rack

Chapter 3 Maintaining the Server

Preparing for Component Installation

Step 1 Check the color of the Power Status LED (see the “Front Panel LEDs” section on page 3-2).

•Green indicates that the server is in main power mode and must be shut down before it can be safely powered off. Go to Step 2.

•Amber indicates that the server is already in standby mode and can be safely powered off. Go to Step 3.

Step 2 Invoke either a graceful shutdown or a hard shutdown:

Caution To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown of the operating system.

•Graceful shutdown—Press and release the Power button. The operating system will perform a graceful shutdown and the server goes to standby mode, which is indicated by an amber Power Status LED.

•Emergency shutdown—Press and hold the Power button for 4 seconds to force the main power off and immediately enter standby mode.

Step 3 Disconnect the power cords from the power supplies in your server to completely power off the server.

Removing and Replacing the Server in a Rack

To remove or replace the server in a rack, follow these steps:

Tip You do not have to remove the server from the rack if you can slide it forward enough to remove the top cover and safely view and access the internal components. Always disconnect all power cords before removing the top cover.

Step 1 Remove a server from a rack:

a.Disconnect all cables from the server. You can leave the cables routed through the CMA.

a.Loosen the two captive thumbscrews that secure the front of the server to each rack post.

b.Pull the server out of the front of the rack until the slide rails stop against the internal lock.

c.Press the removal release clip on each slide rail (see Figure 2-4 on page 2-7), and then continue pulling the server out evenly until it clears the slide rails.

Step 2 Replace a server in a rack:

a.Align the mounting brackets that are attached to the server sides with the front of the empty slide rails.

b.Push the server into the slide rails until they stop against the internal stops.

c.Press the installation release clip on each slide rail (see Figure 2-4 on page 2-7), and then continue pushing the server in evenly until its front flanges touch the rack posts.

d.Tighten the thumbscrews on each flange to secure the server to the rack posts.
