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.
