Cost-effective stackability

– Built-in stacking ports for simpler,

quicker stacking as cascade modules

are not required; sacrificing the GBIC

ports for stacking is not necessary.

Resiliency

– Fail-safe stacking design assures con-

tinuous uptime even if any switch in

the stack should fail.

– Distributed MultiLink Trunking

allows aggregating ports across

different switches in a stack and

provides load balancing and fail-over

protection for uninterrupted access

to the network center.

– Also, for improved network reliability,

BayStack 470-48T supports Split

MultiLink Trunking in conjunction

with two Passport 8600 switches by

providing load sharing among all the

links and fast sub-second fail-over in

case of link failures.

High-availability

– With QoS support, policies can

be created to give certain users or

applications priority for network

resources.*

Security

– Features include BaySecure MAC

address-based security, Radius authen-

tication, SNMPv3 user authentication

and data encryption, password

protection, and EAP (Extensible

Authentication Protocol) over LAN

using IEEE 802.1x.

Key solution benefits

• High-density desktop switching con-

nectivity

• Resilient, fail-safe stacking design and

redundant power support assure con-

tinuous uptime

• Cost-effective, quicker, simpler stacking

• Resilient connectivity to mission-

critical devices for minimal network

downtime

• High uplink capacity using two

built-in GBIC uplinks

• Secure access and data traffic

protection

• Network availability with QoS

features that manage and prioritize

data traffic and users

• Space savings with compact 1U

high form factor

• Suite of common management

software lowers training and

installation costs

Customer qualifications

• Does the customer need high-density

desktop connectivity?

• Is cost a major issue for purchasing

networking equipment?

• Does the customer currently have

(or plan to add) high-bandwidth

or delay-intolerant applications on

your network?

• Are resiliency and security critical

to the customer’s LAN?

• Is space a major issue in the

wiring closet?

Nortel Networks solution

Part of the Nortel Networks successful

BayStack family, the BayStack 470-48T

10/100 Policy Switch is designed to

provide high-density connectivity to

enterprise customers’ wiring closets. Its

Quality of Service (QoS) features ensure

connectivity and network availability by

managing and prioritizing data traffic

and users for maximum performance. It

is a scalable, resilient solution that mini-

mizes capital and operational expenses.

Its security features offer protection

against unauthorized access to data traffic.

The BayStack 470-48T Policy Switch

is a high-density, stackable 10/100 Mbps

Ethernet Layer 2 switch with 48 10/

100BASE-TX ports, two built-in GBIC

uplink ports, as well as built-in stacking

ports in a compact 1U high design.

Scalability

– Up to eight BayStack 470-48T Policy

Switches can be stacked to achieve up

to 384 10/100 ports for high-density

desktop switching.*

Performance

– Two built-in GBIC ports for dedicated

uplink connectivity to network core

switches such as Passport 8600.

– Up to 16 GBIC ports are available

for uplink connectivity in a full stack.

– 2.5-Gbps cascading bandwidth is

higher than competitors.

96-port solution with 1 Gigabit uplink using BPS vs. BayStack 470-48T Switches:

OPTION 1:

BPS (4): $2,595 ea x 4 = $10,380

Cascade module $395 ea x 4 = $1,580

Uplink module (SX MDA): $1,295 ea x 1 = $1,295

Total Costs = $13,255

Total per port cost = $138

OPTION 2:

BayStack 470 (2): $4,495 ea x 2 = $8,990

Cascade module: $0 ea = $0

Uplink module (SX GBIC): $345 ea x 1 = $345

Total Costs = $9,335

Total per port cost = $ 97

TOTAL SAVINGS = $3,920 (30% savings)

Cost comparison
