UTM 425 Operating Instructions

Connection and Conﬁguration

How to connect the appliance is described in the Hardware Quick Start

Guide. For conﬁguration you can follow the initial setup wizard described in

the WebAdmin Quick Start Guide or cancel it and perform a manual setup

(see the Sophos UTM Administration Guide).

SFP GBIC Port

The Sophos UTM 425 is equipped with SFP GBIC ports. The abbreviation SFP

GBIC stands for Small Form Factor Plugable GigaBit Interface Converter and

designates a ﬂexible interface which changes electronic signals into optical

signals. The converters used with the appliance are often also designated as

Mini-GBIC or New GBIC.

To use SFP GBIC ports, you will need the appropriate SFP GBIC modules.

These modules are not delivered with the appliance. You will need to use the

module type most appropriate for the existing network. The following SFP

GBIC module types may be used:

Ì 1000 Base-T: IEEE 802.3 - 1 Gbit/s via Ethernet cable. An Ethernet cable

category 5 covers a maximum distance about 100 meters.

Ì 1000 Base-SX: IEEE 802.3 - 1 Gbit/s via ﬁberglass. Multi-mode ﬁberglass

(MMF) cables can cover a distance of 500-550 m.

Ì 1000 Base-LX: IEEE 802.3 - 1 Gbit/s via ﬁberglass. Here, exclusively

single-mode ﬁberglass is used. The distance which can be covered with

this transmission option is approximately 10 km.

Caution: The SFP GBIC Ports use lasers to transmit signals over ﬁber optic

cable. The lasers are compliant with the requirements of a Class 1 Laser and

are inherently eye-safe in normal operation. However, you should never look

directly at a transmit port when it is powered on.

Installing a SFP GBIC module

Please read the operation manual to the SFP GBIC module. Carefully

insert the SFP GBIC module into the port until it engages. The interface is

immediately ready for use.

Removing a SFP GBIC module

1. Remove the ﬁberglass cable from the module you wish to remove.

2. Remove the module carefully from the port.

Depending on when you purchased your SFP GBIC module, it may have

any of three different release mechanisms: a plastic tab on the bottom of

the mini-GBIC, a wire bail, or a plastic collar around the mini-GBIC.

Please read the operation manual to the SFP GBIC module.
