Nortel Networks 7400 - Manual (Page 17)

• Improves network performance – with a 12.8Gbps
Switch fabric and a forwarding rate of 5.1 million
packets per second (Mpps), the BayStack 420
delivers wire-speed performance with no
packet loss
• Gibabit Uplink option port offers a choice of GBIC
modules with different physical interfaces,
including 1000Base-SX, 1000Base-LX, 1000Base-XD
(for distances up to 50km) and 100Base-ZX (for
distances up to 70km) enabling long haul
connectivity to servers and backbone switches
• Higher bandwidth allocation for server connection
– the BayStack 420 helps you avoid network
bottlenecks with MultiLink Trunking (MLT) support
for up to 6 MLTs per switch or per stack (and up to
4 ports per MLT).
• Virtual LAN support allows network
administrators to manage bandwidth better by
assigning users to the appropriate VLANs and
controlling broadcast and mulicast traffic. Virtual
LANs also simplify network adds, moves and
changes
• Ensures your network is secure – BaySecure MAC-
address Access Control provides enhanced security
by limiting access to the switch based on allowed
source MAC addresses.
• Enhanced administration control – with RADIUS-
based authentication, administrative access to the
switch is password protected.
• Protects your initial investment – grow your
network with the stackable solution that grows.
The BayStack 420 can stack up to 8 switches per
stack and accommodates up to 192 ports per stack.
• Because the BayStack 420 includes built-in
stacking connectors, you enjoy a lower per port
price in stack configuration.
• The BayStack 420 is suitable for your growing
office environment – multi-level floors or nearby
branch office servers (up to 70km away) are
ensured the same connectivity quality and speed.
