1 INTRODUCTIONSwitch 8800 PoEPower RackThe 3Com Switch 8800 PoE power rack is a modular, stand-alone Power overEthernet (PoE) power source. The PoE Power Rack provides a total of 4500 Watts ofDC power with 2+1 power redundancy for PoE powered devices connected to theSwitch 8800 chassis.Features The PoE Power Rack has the following features:■ Compatible with a wide range of input voltages from 90 V to 264 V and uses 20A/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 RS485interface■ Advanced EMC (Electro Magnetic Compatibility) design■ High safety and reliabilityArchitecture andConfigurationsThe 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 generalconfiguration is shown in Table 1.The standard PoE Power Rack is configured with one power supply module. Thepower rack may be configured with up to 3 power supplies based on the power andpower redundancy requirements. Refer to Figure 1 for overall dimensions. Refer toFigure 2 for the rear view of the PoE power rack.Table 1 The PoE Power Rack ConfigurationDescription Standard Configuration4U high chassis D x W x H- 320.5 x 482.6 x 177mm (12.62 x 19.00 x 6.97 in)System controller OneSWITCH 8800 PoEPower Supply ModuleOne installed (3 maximum for power redundancy)AC distributioncomponents■ Three independent AC power input sockets with three AC Powerswitches■ 3-phase AC voltage sensor
