About this task

S036

18 - 32 kg (39 - 70 lb)	32 - 55 kg (70 - 121 lb)

CAUTION

Use safe practices when lifting.

R006 CAUTION Do not place any object on top of a rack-mounted device unless that rack-mounted device is intended for use as a shelf.

S037 CAUTION The weight of this part or unit is more than 55 kg (121.2 lb). It takes specially trained persons, a lifting device, or both to safely lift this part or unit.

Attention

• Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

• Power off the server and peripheral devices, disconnect the power cords from the primary chassis, then disconnect the power cords from the secondary chassis. See Power off the server.

• Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.

Note

• Depending on the configuration, your server might be slightly different from the image.
• The primary chassis is shown below as an example, the secondary chassis is similar.

Procedure

1. Lift the server and place it on a table. Two lifting options are available:

   For two-person lift, remove the following components beforehand: All the power supply units All the storage drives Top cover	Otherwise, lift the server with three people or a lifting device.
   	CAUTION Make sure to lift the server by holding the lift points.
   1 Lift point

2. Remove the inner rails from the intermediate rails.

   Pull the inner rails all the way out until they stop. Lift the lock latches, and pull the inner rails to disengage them from the intermediate rails. Attention There are two pairs of lock latches on the rails. Lift the second pair of latches to proceed to slide the inner rails out. Remove the inner rails.

3. Align the slots on the inner rail with the corresponding T-pins on the side of the server; then, slide the inner rail forwards until the T-pins lock into place with the inner rail.
   
   
   
4. Insert and tighten an M4 screw to secure the inner rail as shown.
   
   
   
5. Repeat the previous two steps on the other rail.
6. Attach the lift handle.

   Pinch both flaps on the side of the handles. Align the handles with the 6 posts on the sides of the server; then slide the handles up to secure them to the chassis. Note Make sure all 6 posts are secured. There are 4 lift handles in total. Make sure to install them all properly before lifting the server.

7. Install the server to the rack.

   		Attention When moving the server, hold the server by its lift points or the lift handles at all time.
   		Attention Before inner rail is inserted into intermediate rail, ensure that the ball retainer is at the foremost of the intermediate rail.

   1. Align both rear ends of the inner rails with the openings in the intermediate rails, and make sure the two pairs of rails mate correctly. Then, carefully slide the server into the rack until the rails snap into place.
      
      
      
   2. Remove the rear lift handles.

      Pinch both flaps on the side of the handles. Align the handles with the 6 posts on the sides of the server; then, slide the handles down to remove them. Note Make sure to remove both rear lift handles before proceeding sliding in.

   3. Lift the first pair of lock latches to proceed to slide the server in until the rails snap into place.
      
      
      
   4. Remove the front lift handles.

      Pinch both flaps on the side of the handles. Align the handles with the 6 posts on the sides of the server; then, slide the handles down to remove them. Note Make sure to remove both front lift handles before proceeding to slide the server in. CAUTION Do not lift the second lock latches until all handles are properly removed.

   5. Lift the second pair of lock latches to proceed to slide the server in.

      Attention Slide the server all the way out and all the way back in to make sure the rails are working smoothly.

8. Connect the external UPI cables to the primary chassis. Make sure the cables match the number and pattern shown on the UPI label.

   1. Close the UPI cover.
   2. Tighten the thumbscrew to secure the UPI cover. Use a screwdriver if needed.
10. Repeat the previous two steps on the secondary chassis to connect and install the external UPI cables.
11. Connect the sideband cables to the primary and secondary chassis.

12. Connect all remaining external cables to the chassis.
13. Reinstall all the components that were removed previously.
14. (Optional) Secure the server to the rack.

    Rear	Front
    1 Hook latch
    Note Use either flat-head, hex socket, or Phillips driver for the following instruction. Insert and tighten an M5 screw along with a washer to the hole below each hook latch. Tighten the thumbscrews. Use a screwdriver if needed.

15. If you have removed a security bezel, reinstall it. See Install the security bezel.
16. Reconnect the power cords to the secondary chassis, then reconnect the power cords to the primary chassis.
    Note

    It is recommended to connect PSU P1-P3/S1-S3 to a PDU different from PSU P4-P6/S4-S6 in case of PDU failure.
17. Reconnect all external cables that you removed.
