Over view
1.1 Configuration
The following sections describe the features and requirements of the Multinet4.
1.1.1 Connectivity
The Multinet4 is equipped with:
•4EthernetPorts
• 2 100FX multi/single mode Fiber, LC, ST, and SC
• 2 10/100 BaseT, RJ45 Auto-negotiation and Auto-MDIX
OR
• 4 10/100 BaseT, RJ45 Auto-negotiation and Auto-MDIX
• 4 programmable RS232/485 serial ports
These ports are all located on the front face of the device, as illustrated in the figure below.
FIGURE 1–1: Front View

1–2 MULTINET4 MULTI-PORT SERIAL SERVER & MANAGED SWITCH – INSTRUCTION MANUAL
OVERVIEW CHAPTER 1: OVERVIEW
1.1.2 Power and Ground
The Multinet4 can be ordered with a high (90 -250 VAC or VDC) or Low (24-48 VDC) voltage
power supply. The connection point for the power supply is located at the rear of the
chassis. The rear face also contains the primary ground stud and labels including serial
number, model number, and port and power specifications, as illustrated in the figure
below.
For detailed power specifications see Table 1–2:: Environmental Specifications.
FIGURE 1–2: Rear View
1.1.3 Indicators
The operational status of the ports of the Multinet4 is indicated by LEDs located near the
physical ports on the front of the Multinet4, as illustrated in FIGURE 1–1: Front View, and a
bank of LEDs on the top of the chassis, as illustrated in FIGURE 1–3: Top View.
