Non-PoE devices

Connect up to 12 Ethernet Switch 470
or Ethernet Routing Switch 4526FX,
4550T, 4548GT and 5510 to provide
power protection to these switches. A
single 600W Redundant Power Supply
Module can protect up to four switches
from power disruption. Use DC cable
AA0005021-E6 to connect four switches
to a single Redundant Power Supply
Module. For maximum deployment
flexibility, a long DC cable of 25 ft/7.6
m is available (AA0005020-E6).

How to choose

Various flexible deployment options are
available for the Redundant Power
Supply 15. It can be used in conjunction
with many Nortel Ethernet Routing
Switches and Ethernet Switches. The
previous table outlines valid combinations. 

• Is network uptime and uninter-

rupted activity critical to your
business?

• Do you have multiple wiring

closet switches?

• Is space limited in your wiring

closets? 

• Do you have multiple high

demanding PoE devices
connecting into you wiring
closet?

Example configuration

This hypothetical example shows the various items required for a customer quotation of
a Redundant Power Supply Unit 15. A customer wants to provide power redundancy
with the Redundant Power Supply 15 to the following Nortel switching products:

• 1 x Ethernet Routing Switch 5510-24T

• 1 x Ethernet Routing Switch 5520-48T-PWR

• 1 x Ethernet Switch 470-48T

• 1 x Ethernet Switch 470-48T-PWR

• 1 x Ethernet Routing Switch 4550T

Your Redundant Power Supply 15 quote should include the following components:

A Redundant Power Supply Unit 15 chassis to house the 600W Redundant Power Supply Modules is

required.

B In total, three 600W modules are needed. All PoE switches need a separate 600W module. In this

example, we need two for PoE switches: one for the Ethernet Routing Switch 5520 and one for the
Ethernet Switch 470-48T-PWR. Three non-PoE switches like the Ethernet Switch 470, the Ethernet
Routing Switch 5510, 4550T or 4548GT require a third 600W module. Now all three slots of the
chassis are filled with 600W Redundant Power Supply Modules. You can choose various power cord
options; this example is without a power cord.

C When connecting non-PoE switches like Ethernet Switch 470, Ethernet Routing Switch 5510, 4550T or

4548GT, you can use the 1:4 cable that allows you to connect up to four switches to one 600W
module. In this example, the customer could add another non-PoE switch in the future.

D When connecting a PoE switch like the Ethernet Routing Switch 4550T-PWR, 4548GT-PWR, 5520-

48T-PWR, 5520-24T-PWR or Ethernet Switch 470-48T-PWR to the Redundant Power Supply unit 15, a
1:1 connecting cable is required to connect each PoE switch to one separate 600W module. In this
example, we have two of these switches, so we need two connecting cables.

E Some switch models require a separate DC-to-DC converter to enable the DC power slot at the back

of the switch and connect a DC cable. This DC-to-DC converter is typical for the Ethernet Routing
Switch 5510 or Ethernet Routing Switch 4526FX, 4550T and 4548GT.

F To connect an Ethernet Switch 470 to the Redundant Power Supply 15, this DC-to-DC converter, that

is specific to the Ethernet Switch 470, is required. Please note that this DC converter is different than
used in ERS 5500 or ERS 4500 series products.
