Nortel Ethernet Routing Switch Redundant Power Supply 15 power
specification
The Nortel Ethernet Routing Switch Redundant Power Supply 15 (RPS 15)
provides a secondary power source for Nortel Ethernet Routing Switch
4500 Series devices. In addition, when connected to a Power over Ethernet
(PoE) switch, such as the 4548GT-PWR or the 4550T-PWR, the RPS 15
can supplement the amount of Direct to Ethernet (DTE) power to deliver up
to 740 watts of PoE.
Nortel DC to DC converter module
To use the Nortel Ethernet Routing Switch Redundant Power Supply Model
15 (RPS 15) with the Nortel Ethernet Routing Switch 4500 Series non-PoE
models, 4548GT, 4550T, and 4526FX requires a DC-DC converter module.
The DC–DC converter module plugs into the slot on the back of a non-PoE
switch and connects the RPS to the switch.
For information about connecting the converter module to the Nortel
Ethernet Routing Switch 4500 Series non-PoE models, 4548GT, 4550T, or
4526FX, see DC-DC Converter Module for the Baystack 5000 Series Switch
(215081-A).
