Attention: To
avoid rail failure and potential danger to yourself and to the unit,
ensure that you have the correct rails and fittings for your rack.
If your rack has square support flange holes or screw-thread support
flange holes, ensure that the rails and fittings match the support
flange holes that are used on your rack. Do not install mismatched
hardware by using washers or spacers. If you do not have the correct
rails and fittings for your rack, contact your IBM® reseller.
Important: The rail installation
can be completed by one person. However, the installation is easier
if one person is positioned at the front of the rack and one person
is positioned at the rear of the rack.
To install the mounting hardware
into the rack, complete the following steps:
- Ensure
that you have the electrostatic discharge (ESD) wrist strap attached.
If not, attach it now.
- Select a rail and remove any parts
that were taped to it for shipping.
- Install the spring to the rail
by hooking one end to the spring bracket (A) and
the other end around the circular standoff (B) as
shown in Figure 1.
Note: If
your rack has the square mounting holes, remove the rail pins from
the rail. Install the larger rail pins that are provided with the
rack installation kit.
Figure 1. Installing
the spring to the rail
- Open the hinge bracket on each
end of the rail.
- Identify the side of the rack
where the rail must be mounted by holding the rail inside of the open
space of the rack as follows:
- The rail points from front
to rear.
- The support ledge (A) is
at the bottom and points toward the center of the open space.
- The enclosure stop (B) points
toward the rear of the rack.
Figure 2. Opening the rail hinge bracket
- Locate the two marks that were
made previously on the Electronic Industries Alliances (EIA) strips.
- Align the rail bracket inside
the rack cabinet beside the marks, and seat the rail bracket pins
in the mounting holes. The bottom of the rail support ledge appears
slightly higher than the U mark on the rack flange.
Figure 3. Mounting the rail on the rack
- At the front of the rail, close
the front hinge bracket to secure the rail to the rack cabinet flange.
Figure 4. Securing the rail to the rack
- While you hold the rail bracket
in place, carefully expand the rail until the other end reaches the
opposite rack flange.
- Seat the pins of the opposite rail
bracket in the marked mounting holes.
- At the rear of the rail, close
the rear hinge bracket to secure the rail to the rack cabinet flange.
- Install one M5 screw in the open
hole in the bracket between the two alignment pins (C).
- Repeat steps 6 - 12 for the other
rail.
