If airflow through the equipment rack and the devices that occupy it is blocked or
restricted, or if the ambient air drawn into the rack is too warm, an over-
temperature condition within the rack and the devices that occupy it can occur.
restricted, or if the ambient air drawn into the rack is too warm, an over-
temperature condition within the rack and the devices that occupy it can occur.
The site should also be as dust-free as possible. Dust tends to clog the server
fans, reducing the flow of cooling air through the equipment rack and the devices
that occupy it. This reduction increases the risk of an over-temperature condition.

Additionally, the following guidelines will help you plan your equipment rack
configuration:
configuration:
Besides airflow, you must allow clearance around the rack for maintenance.
When mounting a device in an open rack, ensure that the rack frame does
not block the front intakes or the rear exhausts.
Temperature and Humidity Guidelines
Table 9 lists the operating and non-operating environmental site requirements for
the SV Director Server. The server normally operates within the ranges listed;
however, if a temperature measurement approaching a minimum or maximum
parameter indicates a potential problem. Maintain normal operation by
anticipating and correcting environmental anomalies before they approach
critical values by properly planning and preparing your site before you install the
server.

Warning! To prevent the system from overheating, do not operate it in an area
that exceeds the maximum recommended ambient temperature of: 95°F (35°C).

Power Considerations
For redundancy, you need to configure the SV Director Server with two AC-input
power supplies. For power supply pinout descriptions, see the
power supplies. For power supply pinout descriptions, see the
. The AC power supplies are hot-swappable.
Warning! Blank faceplates and cover panels serve three important functions:
they prevent exposure to hazardous voltages and currents inside the chassis;
they contain electromagnetic interference (EMI) that might disrupt other
equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are
in place. Statement 1029
