4000 Router Series Interface Module Guide

HMIM

For modular MSR series routers, a wide range of optional HMIMs are available, which provide abundant

interfaces, such as the synchronous/asynchronous serial interface, Ethernet interface, E1/T1, ISDN

BRI/PRI, audio interface, and Layer 2 switching interface.

HMIM-24GSW/HMIM-24GSW-PoE

Introduction

The 24-port 1000M Layer 2 Ethernet interface module (HMIM-24GSW/HMIM-24GSW-PoE) is suitable

for a small enterprise network to serve as a switching & routing device, which can be directly connected

to PCs and network devices of the enterprise. The HMIM-24GSW-PoE supports power transmission to

remote devices over Ethernet cables.

The HMIM-24GSW/HMIM-24GSW-PoE module provides the following features:

• A transmission distance of 100 m (328.08 ft) over straight-through and cross-over Category 5

coaxial cables

• A line rate of 1000 Mbps over straight-through and cross-over Category 5 coaxial cables

• 10/100/1000 Mbps autosensing

• Full duplex (commonly used) and half duplex
