34 Sun Fire 280R Server Setup and Rackmounting Guide • January 2001
Vertical Mounting Rail
Requirements The rack must have two pairs of vertical mounting rails (one
pair in front, one pair in back) that conform to the EIA
(RETMA) standard for mounting hole spacing.
Left-side-to-right-side rail spacing (mounting hole center to
mounting hole center) for front and back rails must be 18.3
inches (46.5 cm).
Front-to-back rail spacing must be at least 26.875 inches
(68.26 cm) and not more than 34.875 inches (88.5 cm) from
the outside face of the front rail to the outside face of the
back rail.
Front and back vertical rail mounting faces must be parallel
with each other and with the front plane of the rack.
Doors and Panels If you are using a Sun expansion cabinet, you can remove
the front door and the side panels to increase access to the
system. Otherwise, see the instructions provided with the
rack enclosure.
EMI Requirements Electromagnetic interference (EMI) shielding requirements
are met by the system chassis and metal side panels, which
remain in place when the unit is rackmounted.
Anti-Tilt Protection The rack must be bolted securely to the floor or equipped
with two sturdy and extendable anti-tip legs. You must
prevent the cabinet from tilting forward when one or more
systems or devices are fully extended out the front of the
rack.
Minimum Service Access An area not less than 3 feet (1 meter) deep and 6
feet (2 meters) wide must be available in front of the
rack for installation and service access.
When fully extended on its mounting rail slides, the system
will protrude 29.75 inches (75.6 cm) forward of the rack’s
front vertical mounting rails.
Fire Containment The rack enclosure must meet Underwriters Laboratories,
Inc. and TUV Rheinland of N.A. requirements for fire
containment.
