power to the switch itself and
connected PoE devices. In this
case a total of 320W of power can
be provided to connected devices
with a maximum of 15.4W per
port as defined in the 802.3af
standard, or an average of 13.3W
to all ports on a 24 port switch, or
6.6W to all ports on a 48 port
switch.
When a 3
rd
party UPS is added, it
ensures continuity of AC power
even during AC mains failure,
power sag, surges, or blackouts.
Additionally the Redundant Power
Supply 15 can protect up to 4 non-
PoE switches
(1

Redundant Power Supply Module.
Up to 3 modules fit in an
Redundant Power Supply 15
chassis.

Routing Switch 5530-24TFD use one
Redundant Power Supply Module per
switch
Power Sharing Mode
When the Redundant Power
Supply 15 is used together with
Ethernet Routing Switch 5520-48T
or Ethernet Switch 470-48T-PWR
internal power supplies, output
power per port can be increased to
full 15.4W on all 48 ports. When
configured to use both internal
and external power (power sharing
mode) the switch total PoE power
output is increased to 740W. In
power sharing mode up to 740W,
or 15.4W per port on a 5520-48T
or 470-48T-PWR can be provided.
Typical applications
PoE devices
Connect up to 3 x 5520-24T,
5520-48T, 470-24T-PWR or 470-
48T-PWR to provide each switch
with 320W for Power over
Ethernet Redundancy or 740W in
power sharing mode. Order DC
cable AA0005018 to connect 5520
or 470-PWR switches.
Non-PoE devices
Connect up to 12 Business Policy
Switch 2000, BayStack 380,
Ethernet Switch 470 or Ethernet
Routing Switch 5510, as well as
Ethernet Services Unit 1400, 1450
and 1800 to provide power
protection to these switches. A
single 600W Redundant Power
Supply Module can protect up to 4
switches from power disruption.
Use DC cable AA0005021 to
connect 4 switches to a single
Redundant Power Supply Module.
For maximum deployment
flexibility a long DC cable of
25ft/7.6m is available
(AA0005020).
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 table below outlines valid
combinations.
Qualification questions:
• Is network uptime and
uninterrupted 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?
