Operating Instructions
Putting into Operation
Caution: Risk of explosion if battery is replaced by an incorrect type. Dispose of
used batteries according to the instructions.
Scope of Supply
The supplied parts are indicated in the Hardware Quick Start Guide.
Mounting Instructions
The SG 310/330 appliances are designed for use in racks. Please consider the
following security tips:
Important Note: Functional reliability outside of a rack cannot be guaranteed.
Warnings and Precautions
The appliance can be operated safely if you observe the following notes and the
notes on the appliance itself.
Rack Precautions
ÌEnsure that the leveling jacks on the bottom of the rack are fully
extended to the floor with the full weight of the rack resting on them.
ÌIn single rack installation, stabilizers should be attached to the rack.
ÌIn multiple rack installations, the racks should be coupled together.
ÌAlways make sure the rack is stable before
extending a component from the rack.
ÌYou should extend only one component at a time—extending two or
more simultaneously may cause the rack to become unstable.
General Server Precautions
ÌReview the electrical and general safety precautions that came
with the components you are adding to your appliance.
ÌDetermine the placement of each component in
the rack before you install the rails.
ÌInstall the heaviest server components on the
bottom of the rack first, and then work up.
ÌAllow the hot plug hard drives and power supply
modules to cool before touching them.
ÌAlways keep the rack‘s front door, all panels and server components
closed when not servicing to maintain proper cooling.

8SG 310/330 Rev. 2
Operating Instructions
Rack Mounting Considerations
ÌAmbient operating temperature: If installed in a closed or multi-unit rack
assembly, the ambient operating temperature of the rack environment
may be greater than the ambient temperature of the room. Therefore,
you should install the equipment in an environment compatible
with the manufacturer’s maximum rated ambient temperature.
ÌReduced airflow: Equipment should be mounted into
a rack with sufficient airflow to allow cooling.
ÌMechanical loading: Equipment should be mounted into a rack so that a
hazardous condition does not arise due to uneven mechanical loading.
ÌCircuit overloading: Consideration should be given to the connection
of the equipment to the power supply circuitry and the effect that any
possible overloading of circuits might have on overcurrent protection
and power supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
ÌReliable ground: Reliable grounding must be maintained at all times.
To ensure this, the rack itself should be grounded. Particular attention
should be given to power supply connections other than the direct
connections to the branch circuit (i.e., the use of power strips, etc.).
Rack Mounting Instructions
To mount the appliance to the rack you need the delivered rack-mount brackets.
There are a variety of rack units on the market, which may mean the assembly
procedure will differ slightly. You should also refer to the installation instructions
that came with the rack unit you are using.
Important Note: Make sure you use the screws supplied with the rack-mount
brackets. Using the wrong screws could damage the hardware appliance and
would invalidate your warranty. Please observe the mounting instructions for
your rack.
1. Attach the rack-mount brackets to the appliance.
Place the appliance on a hard, flat surface with the front panel facing you.
Attach the rack–mount brackets to the left and right side of the appliance
with the supplied screws.
Make sure the brackets are properly attached to the appliance.
2. Choose the rack location.
Leave enough clearance in front of the rack so that you can open the front
door completely (~60 cm/25 inches).
Leave approximately 80 cm/30 inches of clearance in the back of the rack
to allow for sufficient airflow and ease in servicing.
This product is for installation only in a restricted access location (dedicated
equipment rooms, service closets and the like).
3. Slide the appliance into the rack.
4. Attach the brackets to the rack with the appropriate screws (not included).

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.

Operating Instructions
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 which 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.
Serial Console
You can connect a serial console to the COM port of the Sophos SG Firewall
hardware appliances. You can use, for instance, the Hyperterminal terminal
program which is included with most versions of Microsoft Windows to log on to
the appliance console. Use an RJ45 to DB9 adapter cable or the provided USB
cable to connect the console to your hardware appliance.
The required connection settings are:
ÌBits per second: 38,400
ÌData bits: 8
ÌParity: N (none)
ÌStop bits: 1
Access via the serial console is activated by default on ttyS1. The connections of
the appliances and the respective functionality are listed in chapter “Operating
Elements and Connections.”
