Gigabit Ethernet Modules
Gigabit Ethernet connections can be used as network backbones or in a wiring closet. The
following Omni Switch/Router Gigabit Ethernet modules are available:
•GSX-K-FM/FS/FH-2W Advanced switching module with two (2) Gigabit Ethernet back-
bone connections using fiber (SC) connectors.
This module is described and illustrated in the following sections.
♦ Note ♦
Wait at least five (5) seconds after a cable is pulled
from a GSX module before reinserting it. This will
prevent packets from being dropped.
GSX-K-FM/FS/FH-2W
The GSX-K-FM/FS/FH-2W Gigabit Ethernet backbone switching module contains two fiber SC
connectors that support two fully switched 1000Base-LX (long-distance fiber transmissions) or
1000Base-SX (short-distance fiber transmission ports). The GSX-K-FM/FS/FH-2W can be used as
a backbone connection in networks where Gigabit Ethernet is used as the backbone media.
The GSX-K-FM/FS/FH-2W can be factory configured with intermediate-reach single mode or
multimode fiber ports (see GSX-K-FM/FS/FH-2W Technical Specifications on page 3-13 for
more information). The intermediate-reach single mode version is referred to as the GSX-K-FS-
2W; the long-reach single mode version is referred to as the GSX-K-FH-2W; and the multimode
version is referred to as the GSX-K-FM-2W.
The ports are color coded to differentiate the mode: multimode connectors are black, long-
haul single mode connectors are yellow, and intermediate-reach single mode connectors are
blue. (See Handling Fiber and Fiber Optic Connectors on page 3-10 for proper handling of SC
connectors and fiber-optic cable.)
The GSX-K-FM/FS/FH-2W takes advantage of new Gigabit Ethernet/Fast Ethernet ASIC technol-
ogy known as “Kodiak.” This module provides 4 priority levels and 256 queues per Kodiak
ASIC.
♦ Note ♦
Kodiak-based modules support up to 4 levels of prior-
ity (0-1, 2-3, 4-5, 6-7). This is not compatible with the
implementation of VLAN priority of Mammoth-based
modules. Kodiak based priority VLANs can only be
used with other Kodiak based priority VLANs.
With the optional HRE-X you can increase routing performance to 1.5 million packets per
second per module and up to 12 Mpps in a fully-loaded 9-slot chassis.
