Nortel 1424t 规格指南

for workgroups and servers. The GBIC
ports allow for connectivity of single
and multi-mode fiber with support for
Gigabit Ethernet SX, LX, XD, ZX as
well as 1000BASE-T connectivity.
Multi-layer redundancy is delivered by
Multi-Link trunking capabilities that
provide multiple ports acting as one
trunk and the ability to participate as 
a Split Multi-Link Trunk client.

Connecting users was never so simple.
The Passport 1424T comes with auto
polarity and auto sensing built right in.
Auto polarity allows for switch-to-
switch connection with no crossover
cable. Auto sensing provides support 
for 10MB or 100MB speed negotiation.
So whether you are connecting desktops
or switches, 10MB or 100MB—it is 
as simple as plugging in a cable. 

With two built-in GBIC-based uplinks
and support for both SX, LX, XD, ZX,
and 1000BASE-T, the Passport 1424T
provides maximum flexibility for
connections to the network core.
Utilizing both GBICs provides the
maximum in both performance and
reliability for your network. By
supporting a wide range of Gigabit
Ethernet GBICs, connecting the
Passport 1424T to the Passport 8600
network is more simple than ever. 

The Passport 1424T makes good on its
promise of delivering performance to 
the wiring closet. As a desktop routing
switch, the Passport 1424T routing
switch provides the performance, 
simplicity, and flexibility required by
today’s applications-focused network. 
As competition in the global market-
place fuels the growth for network 
applications, Nortel Networks continues
to be uniquely positioned to provide 
customers with the broadest range of
solutions for your business’ success.
