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.
FIGURE 1–3: Top View

CHAPTER 1: OVERVIEW OVERVIEW
MULTINET4 MULTI-PORT SERIAL SERVER & MANAGED SWITCH – INSTRUCTION MANUAL 1–3
1.1.4 Mounting Options
There are four mounting options for the Multinet4:
• 19” rack mount (see section 2.3.1.2 Mounting in a 19” Rail System - General2.3.1.2
Mounting in a 19” Rail System - General)
• 19” rack reverse mount (see section 2.3.1.4 Mounting in a 19” Rail System - Reverse
Mounting)
• Panel mount (see section 2.3.1.5 Mounting on a Panel)
• DIN rail mount (see section 2.3.1.6 Mounting in a DIN Rail System)
Each of these options requires specific accessory hardware. Each type of accessory
hardware mates up with a specific set of screw holes on the sides of the chassis, illustrated
in the figure below.

1.4 Features and Benefits
Multinet4 Multi-Port Serial Server & Managed Switch provides secure multiprotocol
networking in compact, rugged packages purpose-built for power utility substations and
other harsh environments. Cyber-security protection is assured by encrypted per-
connection SSL, and port security features.
1.4.1 Multinet4 Multi-Port Serial Server & Managed Switch
The Multinet4 Serial Port Server & Managed Switch combines the capabilities of an
Ethernet Switch, an Async-to-TCP/IP Terminal Server in a single integrated device.
Dual fiber Ethernet connectivity coupled with Rapid Spanning Tree ensure resilient
backbone communications.
The Multinet4 provides full perimeter protection when used as a terminal server at remote
critical facilities. Per-session encrypted SSL capabilities permit fine-grained security
extended to end-point connections when used as a distributed terminal server in larger
installations.
The Multinet4 is a multi-function, multi-protocol networking platform, purpose-built for
distributed industrial automation applications such as Supervisory Control and Data
Acquisition (SCADA) systems.They support a wide range of communications interfaces
used by industrial devices, enabling multiple generations of remote devices and support
systems to be consolidated onto a single integrated network infrastructure. The Multinet4
also operates effectively in extremely harsh environmental conditions such as those within
power utility substations, pumping stations, treatment plants, transportation systems,
pipelines and wind farms. This robustness is primarily due to extended-range
specifications in areas such as electromagnetic interference, temperature and electrical
surges. Most other networking products will fail when facing these conditions.
The Multinet4 has been rigorously tested to extreme industrial specifications for
temperature, electrical surge protection and immunity. It is packaged in a steel or steel
and aluminum case with no fans or moving parts and has been subjected to
manufacturing test and control processes that include temperature cycling and prolonged
product burn-in to ensure reliability delivered to the field. Physical product reliability is
complemented by advanced network resiliency features that enable redundant and dual-
routed network designs that protect network availability despite facility/element failures.
