Application Brief
Using the Nortel Redundant Power Supply 15
Features & Benefits
• Provides Power Redundancy to Ethernet
Routing Switches 5510, 5520 and 5530,
Business Policy Switch 2000, BayStack 380,
Ethernet Switch 470 and 470-PWR,
as well as
Ethernet Services Unit 1400, 1450 and 1800 .
• Compact packaging. Single chassis, 2U
high for standard 19" rack, provides
scalable, Redundant Power Supply for
multiple devices.
• Highly Efficient. Redundant Power
Supply modules-available in 600 watt
rating-provide redundant DC power to
up to
twelve devices per chassis.
• Flexible deployment. Redundant
Power modules may be purchased
separately and installed into the chassis as
needed, while unit remains fully
operational.
• Protects mission-critical enterprise
applications from interruption due to
problems with either the power source or
power units within network devices.
• Ensures business continuity, when a
3
rd
party UPS is added it ensures
continuity of AC power to switches and
other network devices even during AC
mains failure, power sag, surges, or
blackouts.
Overview
The Nortel Redundant Power
Supply 15 improves network
availability by protecting Nortel
stackable switching solutions from
power outages. The Redundant
Power Supply 15 maintains
network operation in case of
device power failure. Power is
provided to switches
simultaneously without requiring a
device reboot. The modular
chassis allows you to acquire
additional modules as your
network grows. The Redundant
Power Supply Modules are HotSwappable so additional protection
can be added within normal office
hours and without downtime of
the network.
The Redundant Power Supply 15
can be used to provide power
sharing or protection for Nortel
Ethernet Routing Switch 5520 and
Ethernet Switch 470-PWR, as well
as power protection for non-PoE
switches. Up to 12 switches can be
power protected with one
Redundant Power Supply 15
providing maximum efficiency.
For additional resiliency, the
Redundant Power Supply 15
provides customers with the
freedom to choose their corporate
standard Uninterruptible Power
Supply vendor.
The Redundant Power Supply 15
is 2RU high and can accommodate
up to three Redundant Power
Supply Modules. These Redundant
Power Supply Modules provide up
to 600W of power each. The
Redundant Power Supply Modules
feature two front facing LED
indicators to display both status of
AC and DC power. A basic
Redundant Power Supply 15
configuration consists of a chassis
that is shipped with two blank
panels preinstalled. The Redundant
Power Supply 15 requires at least
one hot swappable Redundant
Power Supply Module which must
be ordered as separate item.
Additionally a DC power cable
needs to be ordered to connect to
the DC power socket of the switch.
Depending on the switch type a
separate DC-to-DC converter is
required.
Power Protection Mode
The Redundant Power Supply 15
provides power protection for
Business Policy Switch 2000,
BayStack 380, Ethernet Switch 470,
470-PWR and Ethernet Routing
Switches 5510, 5520 and 5530, as
well as Ethernet Services Unit
1400, 1450 and 1800. In case of a
power outage the Redundant
Power Supply 15 will immediately
take over, providing power to the
switch. Ethernet Routing Switch
5520 and Ethernet Switch 470PWR switches can be configured
to use either the internal or
external power source to provide
Ideal For:
• New and existing mid-tier
and Enterprise Customers
that need RPS functionality
in a single chassis.
• Enterprise Customers
requiring more power for
PoE devices than a single
switch can deliver itself.
• Enterprise customers that
already have a UPS and
only need power
redundancy.
• When there is little space in
the wiring closet and
redundant power is needed
.

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 nonPoE switches
(1
per 600W
Redundant Power Supply Module.
Up to 3 modules fit in an
Redundant Power Supply 15
chassis.

. To provide redundancy to an Ethernet
Routing Switch 5530-24TFD use one

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 47048T-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:

A) 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. 3 NonPoE switches like the Ethernet Switch 470,the Ethernet Routing Switch 5510 or BayStack 380 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 or BayStack 380, 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 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;
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.
G) To connect a BayStack 380 to the Redundant Power Supply 15, this DC-to-DC converter, that is specific to the
BayStack 380, is required.
Please note that although Ethernet Routing Switch 5530-24TFD is not a PoE switch, it has a 1:1 requirement for a 600W Redundant Power
Supply module. Also the DC-to-DC converter is already inbuilt. So from a RPS 15 engineering perspective, you should treat it as if it is a 5520
or 470-PWR switch.
