Sophos SG 310 User Manual

9SG 310/330 Rev. 2
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 Ports
The SG 310/330 models provide the option to add Sophos FleXi Port network
modules with SFP (1 GbE) or SFP+ (1/10GbE) GBIC Ports. The abbreviation SFP
GBIC stands for small form-factore plugable GigaBit interface converter, a flexible
interface which changes electronic signals into optical signals. The converters
used with the appliance are often also called 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 but available through your Sophos
partner. There are different module types. The required type is determined by the
existing network. The following SFP GBIC module types may be used:
SFP:
1000 Base-T
IEEE 802.3 - 1 Gbit/s via Ethernet cable. An Ethernet cable category 5 covers a
maximum distance about 100 meters.
1000 Base-SX
IEEE 802.3 - 1 Gbit/s via fiberglass. Multi-mode fiberglass cables (MMF) cover a
distance of 200 m to 550 m.
1000 Base-LX
IEEE 802.3 - 1 Gbit/s via fiberglass. Here, exclusively singlemode-fiber glass is
used. This transmission option covers approximately 10 km.
SFP+:
10GBase-SR
IEEE 802.3 - 10 Gbit/s via fiberglass. Multi-mode fiberglas cables cover a
distance of up to 400 m.
10GBase-LR
IEEE 802.3 - 10 Gbit/s via fiberglass. Single-mode fiberglas cover a distance of
approximately 10 km
Note: The SFP+ ports of the Sophos FleXi Port modules are dual-rate capable
supporting both 1GbE and 10GbE speeds when using appropriate GBICs also
supporting both rates.
Caution: The SFP GBIC and SFP+ ports use lasers to transmit signals over
fiber optic cable. The lasers are compliant with the requirements of a Class 1
Laser equipment and are inherently eye-safe in normal operation. However, you
should never look directly at a transmit port when it is powered on. Always install
appropriate and UL approved Laser Class I Transceivers, rated 3.3Vdc, max. 1W,
in the fiber ports before using the fiber ports.
