System Rail Assembly (Type 1) - IBM pSeries 630 6C4 Service Manual

System Rail Assembly (Type 1)

Attention: Mounting the rails is a complex procedure. To install the rack rails correctly, you must read,
and then perform each procedure step in the order given. Failure to perform each step in the order given
may cause rail failure.
To install the system rail assembly (type 1), do the following:
1. Select the right rail assembly.
1 Right Rail Assembly (Type 1)
2 Outer Rail Section
3 Rail to System Retaining Screw
Clearance Hole
Note: The system rails are front-to-back and left-to-right side dependent when you are standing in
the front of and facing the rack. The rails are labeled on the front lower corner, left or right.
The back of the rails can be identified by the two large alignment pins and the rail-length
adjusting plate. The top of the rails can be identified by the screws located on the top of the
front and rear rail flange.
2. Position yourself at the front of the rack.
3. Facing the rack, insert the rail's rear-alignment pins into the rack's rear flange holes identified by the
self-adhesive placement dots previously installed.
4. Insert the rail's front-alignment pins into the rack front flange holes identified by the self-adhesive
placement dots previously installed. Ensure that the EIA location is the same from front to back and
the rails are level from front to back.
5. Loosely thread one of the rail-retaining screws into the rail's bottom screw hole. The screw hole is
located one position below the bottom alignment pin.
6. Locate one of the latch brackets, and place the bottom slot of the latch bracket over the rail-retaining
screw.
