CHAPTER 3
Hardware Overview
This chapter describes the front panel and rear panel of the Switch and shows you how to
make the hardware connections.
3.1 Front Panel Connections
The figure below shows the front panel of the Switch.
Figure 8 Front Panel
The following table describes the ports.
3.1.1 Dual Personality Interfaces
There are 24 Dual Personality interfaces, comprising 24 1000Base-T/mini-GBIC combo ports.
For each interface you can connect either to the 1000Base-T port or the mini-GBIC port. The
mini-GBIC ports have priority over the 1000Base-T ports. This means that if a mini-GBIC
port and the corresponding 1000Base-T port are connected at the same time, the 1000Base-T
port will be disabled.
3.1.2 1000Base-T Ports
The Switch has 24 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In 100/1000
Mbps Gigabit Ethernet, the speed can be 100 Mbps or 1000 Mbps. The duplex mode can be
both half or full duplex at 100 Mbps and full duplex only at 1000 Mbps.

CONNECTOR DESCRIPTION
24 Dual
Personality
Interfaces
Each interface has one 1000Base-T copper RJ-45 port and one mini-GBIC (Gigabit
Interface Converter) fiber port, with one port active at a time.
• 24 1000Base-T Ports:
Connect these ports to high-bandwidth backbone network Ethernet switches
using Category 5/5e/6 1000Base-T Ethernet cables.
• 24 Mini-GBIC Ports:
Use Small Form-Factor Pluggable (SFP) transceivers in these ports for
1000Base-X fiber-optic connections to backbone Ethernet switches.
