Chapter 2 Overview

2.1. Introduction to the 3Com Switch 7700

The 3Com Switch 7700 system, shown in Figure 1, is a modular Layer 2/Layer 3, full wire-speed, Ethernet switch
with large capacity. This switch is used to converge the IP layers of a Metropolitan Area Network (MAN), a large
Enterprise Network, or a campus network.

The Switch 7700 supports up to 48 Gigabit Ethernet ports and 288 Fast Ethernet ports and provides a total
switching capacity of 64Gbps.

2.1.2. Modular Hardware Architecture

The Switch 7700 can be installed in a standard 19-inch wide cabinet. The chassis includes slots for modules, fan and
power supplies.
The module area includes one Fabric module slot and 6 I/O module slots. The Fabric
module is mandatory. I/O modules are optional.
The power supply area includes 3 power slots. The switch provides N+1 power source
redundancy backup (2 AC modules are enough for normal operation of the switch) and
supports power load balancing and alarm indication.
The fan slot has one fan frame slot and an operation failure alarm.
