22 Summit24e3 Switch Installation and User Guide
Summit24e3 Switch Overview
Port Connections
The Summit24e3 switch uses a combination of 10BASE-T/100BASE-TX ports using RJ-45 connectors and
Small Form Factor Plugable (SFP) Gigabit Interface Connectors (GBICs), also known as mini-GBICs,
using LC connectors and supports 1000BASE-SX.
Full-Duplex
The Summit24e3 switch provides full-duplex support for all ports. Full-duplex allows frames to be
transmitted and received simultaneously and, in effect, doubles the bandwidth available on a link. All
10/100 Mbps ports on the Summit24e3 switch autonegotiates for half- or full-duplex operation.
Mini-GBIC Type and Hardware/Software Support
The Summit24e3 switch supports the SFP GBIC, also known as the mini-GBIC. The system uses
identifier bits to determine the media type of the mini-GBIC that is installed. The Summit24e3 supports
only the mini-GBIC.
This section describes the mini-GBIC type and specifications.
