There must be no unique maintenance procedures or tools required for
service.
11. Elevated service installations, where the product(s) to be serviced are installed
between 1.5 m and 3.7 m (5 ft. and 12 ft.) above the floor, require the
availability of an OSHA- and CSA-approved nonconductive step ladder. If a
ladder is required for service, the customer must supply the OSHA- and CSA-
approved nonconductive step ladder (unless other arrangements have been
made with the local IBM Service Branch Office). Products installed over 2.9 m
(9 ft.) above the floor requires a Special Bid to be completed before they can
be serviced by IBM service personnel.
For products not intended for rack-mounting to be serviced by IBM, the
products and parts that will be replaced as part of that service must not weigh
over 11.4 kg (25 lb). (Contact your Installation Planning Representative if in
doubt).
12. There must not be any special education or training required for safe servicing
of any of the product(s) installed in the racks. (Contact your Installation
Planning Representative if in doubt).
Rack specifications
When installing a DS5000 storage subsystem or DS5000 storage expansion
enclosure into a non-IBM rack, follow the specifications below.
1. The rack or cabinet must meet the EIA Standard EIA-310-D for 19-inch racks
published August 24, 1992. The EIA-310-D standard specifies internal
dimensions, for example, the width of the rack opening (width of the chassis),
the width of the module mounting flanges, the mounting hole spacing, and the
depth of the mounting flanges. The EIA-310-D standard does not control the
overall external width of the rack. There are no restrictions on the location of
side walls and corner posts relative to the internal mounting space.
The front rack opening must be 451 mm wide + 0.75 mm (17.75 in. + 0.03 in.),
and the rail-mounting holes must be 465 mm + 0.8 mm (18.3 in. + 0.03 in.)
apart on center (horizontal width between vertical columns of holes on the two
front-mounting flanges and on the two rear-mounting flanges).
