Confirm that the customer site meets all requirements before you begin the
installation.
The following table describes site requirements and provides references to additional
information.
Table 1 Site requirements
Description
The system requires a properly equipped computer room with controlled
temperature and humidity, proper airflow and ventilation, proper power and
grounding, system cable routing facilities, and fire equipment.
The system is fed power from two independent power sources, zone A and zone
B. To assure fault tolerant power, customer-supplied AC power must be
connected to independent power distribution units (PDUs).
The system must be acclimated to the new environment before hardware is
installed.
To acclimate the system, place the unpacked system bays in the new operating
environment. Open the front and the rear door of each bay and let the system
stabilize up to four hours in dry conditions and up to sixteen hours in hot and
humid conditions. Do not apply AC power until the system is acclimated to the
local environment.
Dispersed system bays include longer switch and Ethernet cable bundles that
extend the separation distance between system bay 1 and one or more dispersed
system bays.
Cable bundles for dispersed system bays may be routed across the subfloor or in
the overhead ceiling space. If you are not allowed access under the floor or to the
ceiling routing space, ensure that the customer has installed the cable bundles
under the correct floor or ceiling tiles, and has retained the protective packaging
on the cable connectors.
Systems and components must acclimate to the operating environment before
applying power. This requires the unpackaged system or component to reside in the
operating environment for up to 16 hours in order to thermally stabilize and prevent
condensation.
