Introduction
The Enterasys Networks ® D2 family of switches is designed to handle networking demands in a
variety of business and institutional environments. Because the D2 operates with low noise
emissions, this feature rich device is as suited to installation in conference rooms, office cubicles,
and classrooms as it is to wiring closet installations. The D2 switch is a policy‐capable device
powered by external redundant power supplies that support Power over Ethernet (PoE) and other
enterprise class features.

Overview

The D2 product family includes the D2G124‐12 and D2G124‐12P switches, power supply options
(redundant as well as additional power), and switch mounting hardware.

D2G124-12 and D2G124-12P Switches

The D2G124‐12 and D2G124‐12P systems provide twelve copper 10/100/1000 RJ45 ports and two
1‐Gigabit Small Form Factor Pluggable (SFP) fiber‐optic transceiver combo ports. Power over
Ethernet (PoE) is factory installed on the D2G124‐12P.
A D2 switch can be placed on a table‐top as a freestanding unit, installed into a standard
48.26‐centimeter (19‐inch) rack, mounted on a wall, or mounted under a table. The width of the D2
allows for two switches to be installed side‐by‐side into a standard rack. In addition, a
wall‐mounted lockbox is available to secure the unit and cables from tampering after installation
is complete.
The D2G124‐12 and D2G124‐12P switches are shown in Figure 1‐1 and Figure 1‐2 on page 1‐2. The
D2 switch's status LEDs are visible from the front, rear, and top of the switch. Console and
Ethernet ports are located on the rear panel. An add‐on plastic cover can be ordered separately
and installed over the switch when used as a freestanding unit or mounted on a wall.
