Nortel BAYSTACK 470 24 PORT POE SWITCH 仕様ガイド
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 handsets and automatically
configure the port and QoS parameters.
The switch supports a number of pre-
configured MAC address ranges and
also allows users to enter their own
configurable ranges, enabling them to
detect additional Nortel IP handsets
and other vendors’ devices.

When connecting to a device that
supports auto-negotiation, the Ethernet
Switch 470-PWR will automatically
enable the auto-negotiation capability.
This feature provides support for
RFI/FEFI — ensuring that if a single
strand in a fiber pair should fail, the
problem will be detected quickly.

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 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 from an
Ethernet Switch 470 or 470-PWR to
the RPS15 RPSU module (see Ordering
information).

Resiliency Features
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 differentiator for the Ethernet
Switch 470 family, when compared to
competitive switches, 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).
