IBM DCS3700, Installation, User'S, And Maintenance Manual

Page: 173 / 202

2.
When installing a DCS3700 storage expansion enclosure into a non-IBM rack, contact your Installation
Planning Representative to ensure a safe installation into your environment for rack mounting loads
and floor loading. Weight for one DCS3700 fully loaded is 102.27 kg (255 lbs). The load per EIA unit
that a standard EIA rack enclosure must be able to support is 25.49 kg (56.2 lbs) per unit.
3. AC or dc power drawers need to be support based on equipment purchased for the rack or cabinet. It
is strongly recommended that you use a power distribution unit that meets the same specifications as
each unit already installed in the rack. Each power distribution unit needs a dedicated power line.
Rack or cabinet power distribution device(s) must meet the drawer power requirements, as well as
that of any additional products that will be connected to the same power distribution device.
The rack or cabinet power receptacle (power distribution unit, uninterruptible power supply, or
multi-outlet strip) must have a compatible plug type for your drawer or device. The customer is
responsible for ensuring the power distribution unit is compatible with the rack or cabinet and
assumes responsibility for any and all agency certifications required.
4.
The rack or cabinet must be compatible with drawer mounting rails, including a secure and snug fit
of the rail-mounting pins and screws into the rack or cabinet rail mounting holes. You must use the
IBM mounting rails that are shipped with the IBM product to install it in the rack. The mounting rails
that ship with IBM products have been designed and tested to safely support the product during
operation and service activities as well as to safely support the weight of your drawer or device. The
rails must facilitate service access by allowing the drawer to be safely extended, if necessary,
forwards, backwards, or both.
Note: If the rack or cabinet has square holes on the mounting flanges, additional hardware may be
required.
5.
The rack or cabinet must have stabilization feet or brackets installed both in the front and rear of the
rack, or have another means of preventing the rack/cabinet from tipping while the drawer or device
is pulled into its extreme front or rear service positions.
Examples of some acceptable alternatives: The rack or cabinet may be securely bolted to the floor,
ceiling or walls, or to adjacent racks or cabinets in a long and heavy row of racks or cabinets.
