Installing the Memory Array in a 19"
Equipment Rack
The Memory Array fits into a standard 19" (482.6 mm) wide, four-post rack with
sliding rails as specified by EIA-310-D, IEC 60297, and DIN 41494 SC48D.
Square hole racks are supported.
Since there are a variety of 19" equipment racks available, the rack mounting
brackets can be configured in several ways to accommodate a range of front-
rear post spacings–from 24" to 32". This adapts the slide rails to the various
equipment racks that may already exist at a customer's site.
The Memory Array is extended via the slide rails to the front of the rack for live
servicing. A cable management arm is used to manage and extend the cables
for this process. To ensure there is sufficient room for the cable management
arm to easily fit within the rack, it is required that rack depths of 36" or greater
be used. Any doors on the rack must allow good front to back airflow.
Caution:
•
Improperly spaced mounting brackets and slide rails can cause the
Memory Array to fall out of the rack.
•
Because of the weight of the Memory Array, two people are required to
lift and place the system in an equipment rack.
•
If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than the ambient
room temperature. Therefore, consider installing the equipment in an
environment compatible with the maximum ambient operating
temperature specified by the manufacturer.
•
Install the equipment in the rack so that the amount of air flow required
for safe operation of the equipment is not compromised.
•
Mount the equipment in the rack so that a hazardous condition is not
achieved due to uneven mechanical loading.
You must be able to access the rear of the Memory Array and the
Note:
equipment rack during installation.
The following procedure describes how to:
•
Install the sliding rails and mounting brackets onto the chassis if they have
not been installed prior to shipping.
•
Secure the chassis into the equipment rack. The rack mounting screws and
nuts are included in the shipping package.
