Installing the server in the rack enclosure - (NF 8500R - Type 8681)

Installing the server in the rack enclosure

During the installation procedure, you must install parts on the rack enclosure and the server.
This process can be divided into two parts:

•  Preparing the rack enclosure
•  Installing the server

  -Attention-

To ensure rack stability, plan the installation of servers in the rack enclosure starting from the bottom.
 

  -Caution-
Use safe practices when lifting.

Preparing the rack enclosure: In this section, you will use the following components:

•  IBM installation template
•  Four lift handles
•  Two slide-rail-latch assemblies (left and right)
•  Two latch brackets (used with the slide-rail-latch assemblies)
•  Two slide-rail assemblies
•  One cable-management-arm assembly, consisting of:
  •  One bracket
  •  Two rigid arms (upper and lower)
  •  One flexible shaft
  •  Four hinge pins
  •  Five cable-retainer straps

•  Various screws and nuts consisting of:
  •  Eight screws and eight cage nuts or clip nuts (for attaching the slide-rail-assembly to the rack)
  •  Two screws and two cage nuts or clip nuts (for attaching the cable-management-arm-bracket to the rack)
  •  Two screws and two cage nuts or clip nuts (for attaching the slide-rail-latch assemblies)
  •  12 screws (for attaching the server-to-slide-rail-assembly)

•  Three power cords (cables)

  Notes:

1.  The two slide-rail-latch assemblies (left and right) come preinstalled on the server.
2.  The illustrations in this chapter might differ slightly from the hardware or the installation template.

To attach the mounting hardware to the rack:

1.  Refer to the rack enclosure documentation to gain front and rear access.
2.  Mark the positions of the slide-rail assemblies, slide-rail-latch assemblies, and the  cable-management arm on the rack mounting rails:
   1.  Position the installation template on the front mounting rails.
   2.  Mark the location of all the holes on the front of the server (for the slide-rail assemblies and  slide-rail-latch assemblies).
   3.  Move the template to the same level at the rear of the server.
   4.  Mark the location of all the holes on the rear of the server  (for the slide-rail assemblies and the cable-management-arm attachment bracket).

      Note: Some racks come with cage nuts for the mounting rails, whereas other racks come  with clip nuts for the mounting rails.
       To determine the type of mounting hardware that comes with the rack, refer to the rack documentation.
       The illustrations in this chapter show how to install cage nuts.
       If the rack comes with clip nuts, manually slide them onto the mounting rails, as shown in the following illustration.

   5.  Install eight of the cage nuts or clip nuts in the mounting rails at the locations marked for the  slide-rail assemblies.
       See the following (below) illustration.
   6.  Install two of the cage nuts or clip nuts in the mounting rails at the location marked for the  cable-management-arm bracket.
   7.  Install two of the cage nuts or clip nuts at the bottom of the front mounting rails at the location  marked for the slide-rail-latch assemblies.
       
      
   
   
3.  Attach the slide-rail assemblies to the rack:

   Note: The slide-rail assemblies are interchangeable.
    They contain a small amount of grease to lubricate the ball bearings.

   1.  At the rear of the rack, position the slide-rail assembly on the mounting rail and align it over  the cage nuts or clip nuts -1-.
   2.  For the left slide-rail assembly, align the holes marked L (for left) over the cage nuts or clip nuts.
   3.  For the right slide-rail assembly, align the holes marked R (for right) over the cage nuts or clip nuts.
   4.  If required, loosen the nuts -2- on the rear section of the assembly and adjust the slide-rail  assembly to fit over the front and rear mounting rails.
       After the adjustment is made, tighten the nuts.
   5.  Install two screws through the slide-rail assembly and into the cage nuts or clip nuts.
       Do not tighten these screws.
   6.  Make sure the slide-rail assembly mounting holes are over the cage nuts or clip nuts in the front mounting rail.
   7.  With the latch tab pointing down, position the latch bracket -3- in front of the slide-rail assembly.
      •  The latch bracket for the left slide-rail assembly is labeled L.
      •  The latch bracket for the right slide-rail assembly is labeled R

   8.  Install two screws through the latch bracket and the slide-rail assembly and into the cage nuts or clip nuts.
       Do not tighten the screws.
   9.  Attach the other slide-rail assembly to the rack as described in steps 3a through 3f.
   10.  Press the slide-rail assemblies toward the mounting rails and tighten all screws.
   
    
   
4.  Attach the cable-management arms (upper and lower):
   1.  Position the cable-management arm bracket -1- on the rear mounting rail and over the cage nuts  or clip nuts for the bracket.
   2.  Install two screws through the cable-management-arm bracket and into the cage nuts or clip nuts.
       Tighten the screws.
       
      
   3.  Attach the lower rigid cable-management arm to the bracket using one of the hinge pins -2-.
       
      
   4.  Attach the upper rigid cable-management arm to the slide-rail assembly using one of the hinge pins -3-.
       
      
   5.  Connect the two rigid cable-management arms with the flexible shaft using one of the hinge pins -4-.
       
      

Installing the server

  -Caution- Four persons are required to install the server in the rack.

To install the server in the rack:

1.  If the four lift handles are already not installed on the server, install the handles now.
   1.  Press in on the sides of the lift handle near the tabs and insert the handle tabs into the slots on  the sides of the server.
   2.  Move the handle up in the slots until the hooked part of each tab is inside the server.
   3.  Release the pressure on the sides of the handle.
       
      

       
      

        -Caution- Use safe practices when lifting.

2.  Move the slide-rail assemblies to the fully extended and locked position (all the way out of the rack).

   Note: When the slide-rail assemblies are moved all the way out (fully extended), safety latches -1- lock  the rails in place.
    To release the safety latches, press them in toward the server.

3.  Lift the server and move it over the left slide-rail assembly first.
    Make sure that the slide-rail assembly is under the tabs -2-.

    The tabs are farther from the edge on the right side of the server to allow you to maneuver the slide-rail  assembly under the right-side tabs after you have the slide-rail assembly under the left-side tabs.

4.  Next, move the server over the right slide-rail assembly.
    Make sure that the slide-rail assembly is under the tabs.
5.  Once the server is on both slide-rail assemblies, move it toward the rack.
6.  Align the six holes -1- on the left slide-rail assembly with the matching holes on the left side of the server.
7.  Install six screws through the left slide-rail assembly and into the server side. Tighten the screws.
8.  Repeat steps 6 and 7 for the right slide-rail assembly.
    This secures the server.
9.  Remove the lift handles from the server and store them in a safe place.
    
   Note: Although the left and right slide-rail-latch assemblies come preinstalled on the server,  they are detachable.
    If you ever remove them and need to reattach them, you must perform step 10.
10.  Attach the left and right slide-rail-latch assemblies -1- to the server using two screws for each assembly.
     
    
11.  Press the safety latches and slide the server about halfway into the rack enclosure.
12.  Insert and route the cables on the lower cable-management arm first; then, on the upper cable-management arm.

    Note: The server comes with three 220 V AC power cords for connection to the rack power  distribution unit (PDU) in a 200-240 V AC environment.
     Refer to IBM Netfinity Rack Power Distribution Unit (PDU) Installation Instructions  for additional information on installing the PDU.

13.  Attach the power cord, monitor, keyboard, and mouse cables to the corresponding connectors on the server.

      -Attention- When power cords are attached to the rack power distribution unit (PDU), ensure that the  cords are not pinched or chafed by any part of the rack enclosure.

14.  Use the cable-retainer straps to secure the cables to the two cable-management arms.
15.  Secure the server in the rack:
    1.  Slide the server into the rack until each slide-rail-latch assembly locks.

         -Caution- If you are located in an area where
        earthquakes occur, or if you plan to move the server, you must perform the following step.

    2.  Install a retaining screw -1- through the hole at the bottom of each of the slide-rail-latch  assemblies and tighten it.
        
       
16.  To complete the installation, refer to the documentation that comes with the rack enclosure.
