08A-RPS-500
The 08A-RPS-500 provides power backup to an Enterasys PoE-compliant 800-Series switch. If for
some reason the switch looses power from its internal power supply, the 08A-RPS-500 can provide
up to 500 watts maximum operating power to support switch operation and the 48 Vdc necessary
to support 48 Vdc/data connections to PDs (Powered Devices).
Figure 2-23 shows the front and rear view of the 08A-RPS-500 power supply.
