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 Hot-
Swappable 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 470-
PWR 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
.
