PCs and servers. All 24 ports of the

BayStack 460 Switch can be powered.

High-density Power over

Ethernet switch

The BayStack 460-24T-PWR Switch has

24 10/100 Mbps ports, one MDA (Media

Dependent Adapter) slot for uplink connec-

tivity, and one cascade module slot for

stacking. Up to eight switches can be stacked

to achieve up to 224 10/100 ports (using

4-port 10/100 Mbps MDA per switch).

The 2.5 Gbps cascading bandwidth offers

dedicated bandwidth between switches

without sacriﬁcing any uplink ports.

The uplink ports can be used for connec-

tions to backbone switches such as the

Passport 8600 Switch.

Part of the successful BayStack* family,

Nortel Networks BayStack 460-24T-PWR

Power over Ethernet Switch is a resilient,

secure stackable switch with Power over

Ethernet (PoE) capabilities to IEEE P802.3af

draft-compliant devices such as IP phones,

wireless access points, net cameras, security

and lighting devices, and access control

devices (badge readers) (Figure 1).

The switch has all of the features of the

BayStack Business Policy Switch such as

advanced Quality of Service (QoS) and

high-resiliency, with the addition of Power

over Ethernet capability. It enables enter-

prise customers to power devices while

maintaining connectivity to standard

10/100 Mbps Ethernet devices such as

IEEE P802.3af draft-compliant The BayStack 460-24T-PWR Switch is IEEE P802.3af draft-compliant. It can provide Power over Ethernet to any IEEE P802.3af draft-compliant devices such as IP phones, wireless access points, net cameras, security and lighting devices, and access control devices. The benefit of being interoperable with standards-based equipment means that customers are not forced to tie themselves to any one vendor, as the switch has the flexibility to power multiple vendors’ devices.

Passport 8600 network core allows customers to double network bandwidth with no extra investment. The Passport 8600 provides a self-healing network which delivers the reliability and availability required by today’s mission-critical applications. By combining the reliability of the Passport 8600 with the resilient trunking features of the BayStack 460 (DMLT, MLT, etc.), Nortel Networks offers the next generation of flexible networking solutions (Figure 4).

Figure 5: Small to medium enterprise solution Business Communications Manager 400 BayStack 460 Stack Net camera Business Series Terminals 10/100 Mbps Power Standard LAN Power over Ethernet Servers Multiple spanning tree protocol groups The BayStack 460 Switch supports multiple spanning tree groups (STGs). It supports a maximum of eight STGs, either all in one standalone switch or across a stack consisting of several BayStack 460 Switches.

Power sharing options The BayStack 460 Switch can be used in conjunction with the BayStack 10 PSU or NES (Network Energy Source) DC Power System from Invensys (www.intergynes.com) to create a load sharing, RPSU, or UPS solution. Load sharing The BayStack 460 Switch provides up to 200 watts to power the devices. With the addition of a BayStack 10 PSU, up to 235 watts of total power can be supplied to devices. A 2-pin cable is required to connect from the BayStack 460 to the BayStack 10 PSU.

Fault management and resolution With Optivity Network Management System (NMS), the network manager has quick access to the information required to manage and isolate all BayStack 460 networks events. Tools such as Physical Topology View inform the network manager how a particular event is affecting the physical connectivity within the network.

• Avoid QoS provisioning errors • Centrally manage DSCP and 802.1p to queue mapping tables • Save time provisioning the network; thousands of CLI or Web transactions reduced to a few simple actions The BayStack 460 is planned to be supported in OPS version 3.1 (future release). Newer Gigabit Ethernet MDAs The BayStack 460 Switch supports the latest Gigabit MDAs. Each of these MDAs will support 8 output queues and support traffic shaping.
