Perform the following procedure to access the system trays:
Caution: Ensure that you properly shut down the operating system before removing power from
the system. Failure to do so can result in data loss.
1.
Shut down the operating system, and move the system enable switch on the rear of the
enclosure to the OFF position.
Warning:
You must disconnect the workstation from site power (by disconnecting the AC
power cord[s] from the power outlet or the rear of the enclosure) before you attempt to
service any internal components. Failure to maintain proper safety measures while
accessing internal components can expose you to dangerous power levels, resulting in injury
or death.
2. Unplug the AC power cord(s) from the site power outlet and/or the rear of the system.
3. Remove the rear fan assemblies; refer to "Removing the Rear Fan Assembly" on page 42.
Use the following procedure and Figure 1-2 to access the system trays so you can add or replace
components:
1.
Access the system trays (refer to "Accessing the System Trays").
2. Identify the tray that needs to be removed from the enclosure.
3. Disconnect any cables (Ethernet, InfiniBand, USB, etc.) that are connected to the tray. (Be
sure to note which cables connect to which ports, so you can properly re-connect the cables
when you re-install the tray.)
4. Remove the three screws that secure the tray to the chassis and then grasp the handle on the
tray and pull the tray out of the chassis; refer to Figure 1-2.
5. Place the tray on an ESD-safe work surface or package.
