Site Planning

Planning the proper location and layout of your equipment rack or wiring closet is essential for
successful Grid Director 4036E operation. Placing the equipment too close together or in an
inadequately ventilated area can result in overheating of the system. In addition, poor
equipment placement can render system panels inaccessible and difficult to maintain.
To ensure normal operation and avoid unnecessary maintenance, plan your site configuration
and prepare your site before installation.
6.4.1

Rack and Clearance Requirements

The Grid Director 4036E occupies 1U in a 19"rack. You can mount it either way, with the
InfiniBand ports facing the rear or the front of the rack. Switch cooling direction is either from
back-to-front or front-to-back, according to the switch fan unit configuration.
The rack brackets mounting holes conform to the IEA-310 standard for 19-inch racks.
There are no restrictions on rack location.
Mellanox recommends:

Mounting the Grid Director 4036E near the middle of the rack, at or near eye level, to make
it easy to see status indicators, port numbers, etc.

Mounting the rear side of the Grid Director 4036E in a way that enables easy access to the
InfiniBand cables, connectors, and LED indicators.

Leaving a 4" (10 cm) for chassis clearance both at the front and the rear of the chassis.
These requirements are also listed in
6.4.2

Site Environment Specification

For the operating and non-operating environmental site requirements, refer to
Specifications - Power Supply Module
The system can continue to operate within specified environmental ranges; however, a
measurement that approaches the minimum or maximum of a range indicates a potential
problem. You can maintain normal operation by anticipating and correcting environmental
conditions before they exceed the maximum operating range.
6.4.3

Power Requirements

Power requirements are useful for planning the power distribution system needed to support
the Grid Director 4036E. Heat dissipation is an important consideration for sizing the
air-conditioning requirements for an installation. Verify the available power source at the site
for the type of device you are installing:

The Grid Director 4036E requires at least one power connection using standard 3-wire AC
power cords including a safety ground.

The Grid Director 4036E includes two hot-swappable redundant power supplies, providing
full back-up purposes.
