Mounting Instructions

The SG 550/650 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.

6SG 550/650 Rev. 2

Operating Instructions

Rack Precautions

Ì Ensure 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.

Ì In single rack installation, stabilizers should be attached to the rack.

Ì In multiple rack installations, the racks should be coupled together.

Ì Always make sure the rack is stable before

extending a component from the rack.

Ì You should extend only one component at a time—extending two or

more simultaneously may cause the rack to become unstable.

General Server Precautions

Ì Review the electrical and general safety precautions that came

with the components you are adding to your appliance.

Ì Determine the placement of each component in

the rack before you install the rails.

Ì Install the heaviest server components on the

bottom of the rack ﬁrst, and then work up.

Ì Allow the hot plug hard drives and power supply

modules to cool before touching them.

Ì Always keep the rack‘s front door, all panels and server components

closed when not servicing to maintain proper cooling.

Rack Mounting Considerations

Ì Ambient 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.

Ì Reduced airﬂow: Equipment should be mounted into

a rack with sufﬁcient airﬂow to allow cooling.

Ì Mechanical loading: Equipment should be mounted into a rack so that a

hazardous condition does not arise due to uneven mechanical loading.

Ì Circuit 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.

Ì Reliable 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 kits. 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.

Because of their dimension and weight the SG 550/650 models are delivered with a special rail kit.

Important Note: Make sure you use the screws supplied with the rack-mount kits. 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 kits to the appliance.

Place the appliance on a hard, ﬂat surface with the front panel facing you.

Attach the rack–mount kits to the left and right side of the appliance with the supplied screws.

Make sure the kits are properly attached to the appliance.

Important note: The rails for SG 550/650 will ﬁt a rack of 600 mm/23.6” deep.

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.

Please refer to the dedicated sliding rails mounting instructions from the scop of supply.

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 SG Firewall Administrator Guide).

Operating Instructions

RAID (SSD) System

The SG 550/650 model are equipped with a RAID system with two Solid State Drive. A RAID system (redundant array of independent disks) connects several physical Solid State Drive to one particularly performing logical drive. This type of Solid State Drive system enhances the transfer rate and data security. Additionally, a RAID system increases the availability of the security appliance since a defective Solid State Drive can easily and quickly be exchanged—it is not necessary to shut down the system.

Important note: If you need to change a Solid State Drive because of a defect, remember to remove the defective Solid State Drive from the RAID system, otherwise the complete security appliance will fail. Please note that the safe operation of the hardware appliance is only ensured in the long term if both Solid State Drive are working. Immediately exchange damaged Solid State Drive. Only use Solid State Drive which you purchased directly from Sophos or from a Sophos distribution partner. Please remember that any warranty claims are voided for the appliance if a defect has been caused by the use of Solid State Drive which are not suited for the system.

Exchanging the hard disk

1. Identify the defective Solid State Drive.

In the event of a hardware defect the FAIL LED of the respective Solid State Drive will turn on e.g., SSD 1 (upper Solid State Drive).

2. Open the Solid State Drive latch.

3. Unlock the Solid State Drive by pushing the latch to the left and pulling the lever in your direction.

4. Remove the Solid State Drive from the chassis.

5. Now, insert the new Solid State Drive into the chassis.

6. Lock the Solid State Drive by pushing the lever in the direction of the chassis. Lock the latch at the Solid State Drive.

Important note: Except for short periods of time (e.g., swapping Solid State Drives), do not operate the server with an empty Solid State Drive.

As soon as the security appliance detects the new Solid State Drive, the existing hard disk is mirrored to the new Solid State Drive. This process may take 30 minutes or more.

Redundant Power Supply

The SG 550/650 models are equipped with a redundant power supply. The power supply system consists of two separate power supply units. This power supply system increases the availability of the security appliance, since a defective power supply unit can be exchanged easily and quickly during operation.

When the system is running error-free, LED on the back of the appliance shows green. In the event of a hardware defect in one of the power supply units these LEDs will turn red and you will hear a continuous beeping sound. The warning sound can be reset by pressing the red buzzer reset switch on the system chassis. This buzzer reset switch is on the back of the appliance right beside the power supply system.

Operating Instructions

Important note: If you need to change a power unit because of a defect, remember to remove the defective power unit from the power supply system, otherwise the whole security appliance will fail.

Protect yourself from potential burns by wearing protective gloves when exchanging a power supply unit.

Only use power units which you purchased directly from Sophos or from a Sophos distribution partner. Please remember that any warranty claims are voided for the security appliance if a defect has been caused by the use of power units which are not suited for the system.

Exchanging a power supply unit

1. Identify the defective power supply unit.

Locate the defective power supply unit by examining the individual LEDs of each unit—no LED light indicates a failure of the unit.

2. On the right side, open the interlock of the power supply unit.

3. Use the special bracket to pull the power supply unit out of the chassis.

4. Now, insert the new power supply unit into the chassis.

5. Lock the new power supply unit.

Plug the power cable back into the connector of the new power supply unit and check the following LED displays: LED of the new power supply unit lights green. As soon as the new power supply unit is detected and functional, the beeping sound will disappear.

SFP GBIC Ports

The SG 550/650 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.

10SG 550/650 Rev. 2

Page 12

Operating Instructions

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.

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 the provided RJ45 to DB9 adapter cable to connect the console to your hardware appliance.

The required connection settings are:

Ì Bits per second: 38,400

Ì Data bits: 8

Ì Parity: N (none)

Ì Stop 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.”
