without sacrificing any uplink ports. The
Ethernet Switch 460-24T-PWR can also
be stacked with Ethernet Switch 470 or
470-PWR. The uplink ports can be used
for connections to backbone switches
such as the Ethernet Routing Switch
8600, 8300, 1600 or 5500.

Power over Ethernet
(470-PWR)
(470-PWR)
IEEE 802.3af compliant
The Ethernet Switch 470-PWR provides
IEEE 802.3af standards-compliant
Power over Ethernet (PoE) and is
designed to power devices such as IP
phones, wireless access points, network
cameras, security and lighting devices,
and access control devices (badge readers).
The benefit of being interoperable with
standards-based equipment means that
customers are not forced to tie them-
selves to any one vendor, as the switch
has the flexibility to power multiple
vendors’ devices. The switch can supply
power up to 15.4 Watts per port, which
meets the IEEE 802.3af standard.

Dynamic power management
Each port on the Ethernet Switch 470-
PWR can be configured to limit the
power delivered to a device. Each port
can also be configured for power
priority level — low, high and critical.
On the switch, total available power is
monitored. In the case where all avail-
able power is fully utilized, the switch
may turn off lower priority ports and
turn on higher priority ports.

The Ethernet Switch 470-PWR can
automatically disable a port if there is a
short. All other ports on the switch will
remain active and will not be affected by
the disabled port.

Plug-n-play IP Telephony switching
Automatic Discovery and Automatic
Configuration (ADAC) capability
enables the switch to detect Nortel IP
Phones and automatically configure the
port and QoS parameters. The Ethernet
Switch 470-PWR provides simplified
Java Device Manager and Web-based
configurations on data and power prop-
erties. These graphical user interfaces
make it simple to set up data and power
configurations.

Load sharing and redundant
power for 470-PWR
power for 470-PWR
Ethernet Switch 470-24T-PWR or 470-
48T-PWR provides up to 370 watts of
DTE power for Power over Ethernet
devices. With the addition of a Redun-
dant Power Supply RPS15 chassis and
the 600-watt RPS15 power module, the
Ethernet Switch 470-48T-PWR can
support up to 740 watts of power. This
solution will provide 15.4 W per port
from the Ethernet Switch 470-48T-PWR.
Additionally, the addition of an RPS15
chassis and power supply can be used to
provide dual power feeds to the switch,
ensuring higher availability where
customers require their switches connected
to more than one power feed. A DC
connector cable is required to connect

Resilient Stacking
Two Built-in Stacking Ports
Ethernet Switch 470 models have two
built-in stacking ports for simpler,
quicker and more cost-effective stacking.
This unique stacking design frees up
both of the uplink ports for dedicated
connectivity to the backbone. A
46cm/18” stacking cable is included
with the product (Figure 1).

A key differentiation for the Ethernet
Switch 470 family is its resilient stacking
feature. This switch can stack up to
eight units with a resilient cascade
stacking design, assuring continuous
uptime even if a switch in the stack
should fail (Figure 2).

Auto Unit Replacement
The Auto Unit Replacement (AUR)
feature provides the user with the ability
to retain the configuration (CFG) image
of a unit in a stack during a unit replace-
ment. The retained configuration image
from the old unit can be restored to the
new unit. This feature saves time and
effort required to replace a failed unit.
