IBM 8202-E4B Manual page 211

v If the rack or cabinet has doors, the rack becomes a fire enclosure by definition and must meet the
applicable flammability ratings (V-0 or better). Totally metal enclosures at least 1 mm (0.04 in.) thick are
considered to comply.
Nonenclosure (decorative) materials must have a flammability rating of V-1 or better. If glass is used
(such as in rack doors) it must be safety glass. If wood shelves are used in the rack/cabinet, they must
be treated with a UL Listed flame-retardant coating.
v The rack or cabinet configuration must comply with all IBM requirements for "safe to service" (contact
your IBM Installation Planning Representative for assistance in determining if the environment is safe).
There must be no unique maintenance procedures or tools required for service.
Elevated service installations, where the products 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 require 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.
There must not be any special education or training required for safe servicing of any of the products
installed in the racks. Contact your Installation Planning Representative if you are in doubt.
