NTRODUCTION
The 3Com Switch 8800 PoE power rack is a modular, stand-alone Power over
Ethernet (PoE) power source. The PoE Power Rack provides a total of 4500 Watts of
DC power with 2+1 power redundancy for PoE powered devices connected to the
Switch 8800 chassis.
The PoE Power Rack has the following features:
Compatible with a wide range of input voltages from 90 V to 264 V and uses 20
■
A/250 VAC EN60320 C20 appliance coupler connectors and connector plugs.
Power factor is above 0.99
■
Efficiency is over 88%
■
Maximum device output is (N + 1) 90A @ 54V
■
Power supply modules are hot-swappable for uninterrupted operation
■
The PoE Power Rack power status may be monitored by an RS232 or RS485
■
interface
Advanced EMC (Electro Magnetic Compatibility) design
■
High safety and reliability
■
The PoE Power Rack architecture integrates DC power supply modules (3 maximum),
a system controller, and the distribution module, in a four rack-unit-high (4U) chassis.
The system controller provides local monitoring and control of the device. The general
configuration is shown in Table 1.

The standard PoE Power Rack is configured with one power supply module. The
power rack may be configured with up to 3 power supplies based on the power and
power redundancy requirements. Refer to Figure 1 for overall dimensions. Refer to
Figure 2 for the rear view of the PoE power rack.
