Universal Rail Kit
Hitachi Data Systems offers the following third-party Universal Rail Kit 19-
inch rack-mount rail support kits for rack mounting devices in third-party
racks:
• Corner Rail kits for use with 2U trays - Minkels A3BF-HK-GL-740-LR (Rev.
D) - Corner Guide Rail
• Uinversal rail kits for use with 3U and 4U trays - Minkels A34V-445-900-
UNI33
The contents of the kits are:
• Inner rail assembly left
• Inner rail assembly right
• Four M5 flat-head screws
• Four M5 cage nuts
The kits offer the following adjustability and load-bearing limit:
• Minimum depth adjustability:23.8 inches (606 mm)
• Maximum depth adjustability:33.1 inches (842 mm)
• Load-bearing limit: 150 lbs (68 kg)
The following procedure describes how to install a Universal Rail Kit 19-inch
rack-mount rail support kit (see
Figure C-6 Installing the t rail kit on page
C-12). When using a third-party rack, ensure that the rack meets or exceeds
the specifications of the Hitachi rack described in this chapter.
1. Install the first inner rail assembly (either the left or right):
2. Loosen the hex nuts at the rear of the support rail kit to adjust for the
depth of the storage component to be rack mounted.
3. Orient and insert the caged nuts into the square EIA rail flanges (one
front and one rear per side).
4. Align the support rail flange holes with the caged nuts and install the front
screw to secure the assembly in place.
5. Install the M5 screw at the rear of the cabinet and tighten to 1.0 N-m /
8.85 in-lbs. If a torque wrench is not available, tighten the screw to hold
the rail firmly in place. Be careful not to overtighten.
6. Install another M5 screw at the front of the cabinet and tighten to 1.0 N-
m / 8.85 in-lbs.
