Ventilation Requirements; Power Requirements - 3Com 4007 Getting Started Manual

Ventilation Requirements

This section describes ventilation requirements for the
Switch 4007. The chassis contains one fan tray that
contains four fans.
To ensure that installed fans are able to provide
adequate ventilation, maintain at least 7 cm (2.76 in.)
between the sides of the Switch 4007 chassis and the
nearest wall (or other vertical surface). Also provide at
least 91.4 cm (36 in.) behind the chassis to be able to
remove and replace power supplies in the
Switch 4007 chassis.
When you face the front of the Switch 4007 chassis,
the inlet is on the right and the exhaust is on the left.
CAUTION: Operate a Switch 4007 chassis with four
fans running. If one fan in the fan tray fails, replace
the fan tray as soon as possible.

Power Requirements

This section list power requirements for the 930-watt
AC (Model Number 3CB9EP9) power supply.
The Switch 4007 chassis can contain two modular
930-watt power supplies. The 930-watt power
supplies provide AC power to the Switch. The
930-watt power supplies are autosensing. Each
power supply can automatically sense the type of
input voltage to which it is being connected at the
electrical outlet.
