Appliance Hardware

There are certain hardware differences between the various appliance models, which are summarized in the following table or discussed in the sections below.

Feature WS100 WS500 WS1000 WS1100 WS5000 SM2000 SM5000
Processors dual-core, light capacity dual-core, medium-capacity dual-core, high-capacity quad-core, high-capacity quad-core, high-capacity quad-core, high-capacity quad-core, high-capacity

Note
Operating in bridged mode is only possible on a Web Appliance with a bridge card installed.

The Sophos Web Appliance is a high-performance appliance designed to handle web proxy access for organizations of various sizes. The Web Appliance is scalable to much larger numbers of users by grouping multiple Web Appliances by joining them to a single Management Appliance. The appliances raise alerts via the administrative web interface and via email if any hardware components are not functioning optimally.

This section describes the front and back panel LEDs, powering the appliances down gracefully, and hardware-related alerts. The Sophos Management Appliance provides centralized policy configuration and centralized reporting for grouped appliances, thus minimizing system administration work while providing organization-wide information without sacrificing security or customizable web use control.

The appliances have a number of ways to alert you if there is a problem with one of their hardware components. In addition to status indicators in the administrative web interface and alerts sent via email, the appliances have LED indicators and audible alarms.

Front Panel LEDs

Indicators on the front of each appliance provide status information and warnings. The arrangement of the front panel LEDs are the same for the WS100, WS500, WS1000, WS1100, and the SM2000. The indicators on the front of the SM5000 are slightly different, and the indicators on the front of the WS5000 are also slightly different. Each variant is shown in the following diagrams.

WS100 WS500, WS1000, WS1100, & SM2000
SM5000 WS5000
Key LED Color State Indicates
Temp. Sensor Red On System Overheated
      Off System Normal
Unit ID LED (SM5000 only) Blue Off Shows rack location front and back
NIC1 (config) Green On Linked
      Blink Config connection established
      Off Disconnected
NIC2 (non-bridged only) Green On Linked
      Blink Config connection established
      Off Disconnected
HDD LED Amber Blink HDD Activity
      Off No Activity
Power LED Green On System On
      Off System Off

The front panel LEDs are on the upper-right corner of the front panel, to the left of the reset and power buttons (and to the right of the Unit ID button on the SM5000).

Important
Sophos strongly suggests that you use the software shutdown and restart options as documented on the System Status page. Although a quick press and release of the appliance's power button will perform an elegant shutdown, if the power button is held down for four seconds or more, an inelegant, immediate shutdown is performed. Also, the reset button on the appliance always triggers an inelegant, immediate restart, so again the software option is preferred. Using the appliance's power and reset buttons may lead to file corruption and data loss.

Rear Panel LEDs

Indicators on the rear of each appliance provide status information and warnings. The arrangement of the rear panel LEDs depend upon whether the appliance is configured with a bridge card. There is always a bridge card in a WS1000. Bridge cards are optional for the WS500 and WS1100. There is never a bridge card in a WS100, SM2000, or SM5000.

For appliances with no bridge card:

There are two RJ45 network ports along the bottom of the appliance to the right of the middle:

  • The Config port : This is the port to which you connect your laptop or PC to run the setup wizard.
  • The Network port : This is the port to which you make your LAN connection after the setup wizard has been completed.

The two LEDs at the top of these ports indicate the following:

LED Position Color Indicates
Left Green 100 Mbps
Left Amber 1 Gbps
Right Blinking Yellow Port active

For appliances with a bridge card:

There is one RJ45 network port along the bottom of the appliance to the right of the middle, the Configuration port . This is the port to which you connect your laptop or PC to run the setup wizard.

The two LEDs at the top of this port indicate the following:

LED Position Color Indicates
Left Green 100 Mbps
Left Amber 1 Gbps
Right Blinking Yellow Port active

There is also a group of six LEDs to the left of the WAN and LAN ports on the bridge card, which is located in the upper right corner on the back of the appliance. The LEDs are arranged in two columns of three lights, with the left and right columns being indicators for the LAN and WAN connections, respectively. The rows of LEDs are interpreted as follows:

  • Bypass: If all of the top four indicator lights are on, the appliance is in bypass mode.
    • 1000 (top): On indicates a 1000Mbps connection is established; blinking shows traffic; off indicates no connection.
    • 100 (middle): On indicates a 100Mbps connection is established; blinking shows traffic; off indicates no connection.
  • Act/Link (bottom): On indicates a connection at any speed is established; blinking shows traffic; off indicates no connection.

Hardware Alerts

Depending on the severity of the issue, the appliances will raise an alert in the administrative web interface or via email, or both. Alerts advise that devices are not working normally or draw attention to potential problems. In most cases, the alert will instruct you to contact Sophos Technical Support.

Powering Down the Appliances Gracefully

Power down the appliance gracefully by either pressing the power button briefly, or by clicking Shutdown on the System Status page. The appliance will safely shut down its software, and the fans will stop. Remove the power cord before servicing the unit.
Note
You can also power down by holding the power button for four or more seconds, which will force an immediate shutdown of the appliance; however, this may cause a corruption of the file system. Avoid immediate shutdown except in cases when graceful shutdown is not possible.
