2: Server Installation
Check the Node Board Setup
Use the information in the following sections to check that each node board (serverboard) is
properly installed and all the connections have been made.
Each of the four serverboards act as a separate node in the system. As independent nodes, each
may be powered off and on without affecting the others. In addition, each serverboard is a
hot-swappable unit that may be removed from the rear of the chassis. The nodes are connected to
the server backplane by means of an adapter card.
Important: A guide pin is located between the upper and lower nodes on the inner chassis wall.
This guide pin also acts as a “stop” when a node is fully installed. If too much force is used when
inserting a node this pin may break off. Take care to slowly slide a node in until you hear the
“click” of the locking tab seating itself.
Access the Chassis
1. Disconnect all power and data cables for the server you will remove from the rack.
2. Grasp the two handles on either side and pull the unit straight out of the rack until it locks
(you will hear a “click”).
Note: To remove the system from the rack completely, depress the locking tabs on the chassis
rails (push the right-side tab down and the left-side tab up) to continue to pull the system out
past the locked position.
3. Use two people to move the chassis to a stable static-free work surface.
4. Extract and check the condition of the serverboards using the information in the following
subsections.
Extracting a Serverboard From the Chassis
Each of the four serverboards in the chassis is contained in a “drawer” that can be pulled out from
the rear of the enclosure, see
Figure 2-3 on page 17 .
Use standard static precautions when handling the system serverboards.
