Gbe Large Module; Chassis Ethernet Ports - Avaya 2330 Manual

Secure Router 2330/4134 Ethernet interface fundamentals
SFP is detected, the system defaults to copper only. If an SFP is detected, the system defaults
to fiber only.

GbE Large Module

The 44-port 10/100/1000 Large Module provides 44 Ethernet ports that each support
10/100/1000 Mbps operation over unshielded twisted pair (UTP) wiring, as well as two SFP
optical ports. Up to 44 ports can be in use at one time.
The 44-port GbE Large Module provides both Layer 2 switching and Layer 3 routing
functionality. The total available bandwidth at all of the ports (44 Gbps) is four times the
available routing bandwidth.
There are three groups on the module: one group has 12 ports, and two groups have 16 ports
each. For Layer 2 switching within each group, packets can be switched at full bandwidth.
However, for Layer 2 switching between groups and for all packets that are routed (Layer 3),
all external ports must share a limited number of links on the module. There are three links
available within the group of 12 ports, and there are four links available within each group of
16 ports. There is, therefore, a 12:3 (4:1) or 16:4 (4:1) contention for the internal links.

Chassis Ethernet ports

In addition to the module Ethernet ports available for the Secure Router 2330/4134, the router
has four chassis Ethernet ports on the front panel:
• GE 0/1 and GE 0/2 ports — 10/100/1000 Base-T ports
• GE 0/3 and GE 0/4 — SFP ports
The following figure shows the location of the chassis Ethernet ports.
