Chapter 1
NOTE Older racks (with the words "HP Systems" on the nameplate)
may require that enclosures to be tied together before any
components are mounted inside them. To avoid problems, if
older rack versions are to be tied together, do so before
installing slide members, rails, shelves, units, or other
hardware. Otherwise, you may have to remove components
from the rack to gain access to the tie-bolt locations.
2. If present, remove the front and rear doors to increase accessibility inside
the rack. Follow instructions shipped with the rack to do so.
NOTE
Older racks (with the words "HP Systems" on the nameplate)
may also require door hardware to be in place before mounting
components. If you are using front or rear doors on older
models of the HP Systems Rack, be sure the hinge and latch
hardware is mounted before putting on any other hardware.
This prevents later disassembly.
WARNING
When the back door of a rack is removed, the hinge and latch
catch brackets protrude. To avoid injury, temporarily remove
these brackets prior to installing components into the rear of
the rack.
3. If present, remove side panels to allow better access. Follow instructions
included with the rack to do so.
8. Install Fans If Required and Redundant Switch and UPS First If You Have Them
1. If an extractor fan unit is to be used, install it following instructions which
accompany the unit.
NOTE
Most HP NetServers have an internal fan system. However,
rack doors must be perforated (front and rear). In this case, you
do not need an extractor fan.
2. If an Uninterruptible Power Supply (UPS) is used, install the UPS
mounting rails and fasten the unit in place following instructions which
accompany it. Place the UPS equipment in the lowest EIA Units of the
rack. Plug the UPS in to charge the batteries as soon as possible.
