Fast (100 Mbps) Ethernet Modules
Alcatel’s Omni Switch/Router Fast Ethernet modules can be used to connect networks with
100 Mbps workstations or as a network backbone.
The following Omni Switch/Router Fast Ethernet modules are available:
•
ESX-K-100FM/FS-16W Advanced switching module with sixteen (16) Fast Ethernet (100
Mbps) backbone connections using MT-RJ ports.
This module is described and illustrated in the following sections.
ESX-K-100FM/FS-16W
The ESX-K-100FM/FS-16W Omni Switch/Router Fast Ethernet switching module has sixteen (16)
fiber MT-RJ ports that each support a fully-switched 100 Mbps connection in full-duplex mode.
This module provides high-speed backbone connectivity. It also supports backbone features
such as 802.1q and OmniChannel. Each port uses the full 100 Mbps of bandwidth in each
direction (see ESX-K-100FM/FS-16W Technical Specifications on page 3-20). The single mode
version is referred to as the ESX-K-100FS-16W; the multimode version is referred to as the ESX-
K-100FM-16W. Multimode and single mode connectors are differentiated by color: multimode
connectors are black and single mode connectors are blue.
♦ Note ♦
If your network currently uses
SC connectors, you can
order MT-RJ-to-SC cables from Alcatel.
The MT-RJ fiber port supports full-duplex operation. You can configure half-duplex mode on
each port through 10/100cfg. An additional software command, 10/100vc, allows you to view
the current line speed and link mode of each port connection. The 10/100cfg and 10/100vc
commands are described in Chapter 15, “Managing Ethernet Modules.”
The
ESX-K-100FM/FS-16W is best used as a backbone connection in networks where Fast Ether-
net is used as the backbone media. Each 100Base-Fx port may also connect to a single high-
traffic device, such as a mail or file server.
The
ESX-K-100FM/FS-16W takes advantage of new Gigabit Ethernet/Fast Ethernet ASIC technol-
ogy known as “Kodiak.” This module has 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.
