DGS-3048 Gigabit Ethernet Switch Manual 3 Identifying External Components This chapter describes the front panel, rear panel, side panels, and LED indicators of the DGS-3048. Front Panel The front panel of the Switch consists of LED indicators, an RS-232 communication port, 48 1000BASE-T ports, and four mini-GBIC combo ports. Figure 3-1. Front Panel View • An RS-232 DCE console port for setting up and managing the Switch via a connection to a console terminal or PC using a terminal emulation program. • Comprehensive LED indicators display the status of the Switch and the network (see the LED Indicators section below). • Forty-eight 1000BASE-T Ethernet ports for 10/100/1000 connections to a backbone, end stations, and servers. • Four mini-GBIC combo ports to connect fiber optic media to another Switch, server, core router Switch, or network backbone. Rear Panel The rear panel of the Switch contains an external Redundant Power Supply connector and an AC power connector. Figure 3-2. Rear Panel View • The external Redundant Power Supply connector is used to connect the DGS-3048 to a DPS-500. An auto-Switch circuit automatically switches to an external RPS once the internal power supply fails. Transition from internal to external supply shall not disturb normal operation. • The AC power connector is a standard three-pronged connector that supports the power cord. Plug the female connector of the provided power cord into this socket, and the male side of the cord into a power outlet. Supported input voltages range from 100 ~ 240 VAC at 50 ~ 60 Hz. Side Panels The right side panel of the Switch contains two system fans (see the top part of the diagram below). The left side panel contains heat vents. 6

Identifying External Components
This chapter describes the front panel, rear panel, side panels, and LED indicators of the DGS-3048.
Front Panel
The front panel of the Switch consists of LED indicators, an RS-232 communication port, 48 1000BASE-T ports, and four
mini-GBIC combo ports.
Figure 3-1. Front Panel View
•
An RS-232 DCE console port for setting up and managing the Switch via a connection to a console terminal or PC
using a terminal emulation program.
•
Comprehensive LED indicators display the status of the Switch and the network (see the LED Indicators section
below).
•
Forty-eight 1000BASE-T Ethernet ports for 10/100/1000 connections to a backbone, end stations, and servers.
•
Four mini-GBIC combo ports to connect fiber optic media to another Switch, server, core router Switch, or
network backbone.
Rear Panel
The rear panel of the Switch contains an external Redundant Power Supply connector and an AC power connector.
Figure 3-2. Rear Panel View
•
The external Redundant Power Supply connector is used to connect the DGS-3048 to a DPS-500. An auto-Switch
circuit automatically switches to an external RPS once the internal power supply fails. Transition from internal to
external supply shall not disturb normal operation.
•
The AC power connector is a standard three-pronged connector that supports the power cord. Plug the female
connector of the provided power cord into this socket, and the male side of the cord into a power outlet. Supported
input voltages range from 100 ~ 240 VAC at 50 ~ 60 Hz.
Side Panels
The right side panel of the Switch contains two system fans (see the top part of the diagram below). The left side panel
contains heat vents.
