LAN 1-4

Local Area Network switch: Four Ethernet ports (RJ-45) used for connecting computers or other network devices

DMZ/
WAN2

DMZ/WAN2 switch: Two ports used for connecting a DMZ (Demilitarized Zone) computer or network:

• An Ethernet port (RJ-45) on the left
• An SFP (Small Form-factor Pluggable) port on the right

Alternatively, can serve as a secondary WAN port or as a VLAN trunk.

Only one of these ports can be used at a time.

DSL

An RJ-11 ADSL port used for connecting the integrated ADSL modem to an ADSL line.

A splitter with a micro-filter is usually required when connecting this port to the phone jack. If unsure, check with your ADSL service provider.

Before connecting this port to the line, make sure that you are using the correct UTM-1 model for your phone line: Annex A for POTS (regular) phone lines, and Annex B for ISDN (digital) phone lines. Your UTM-1 model's ADSL annex type appears on the bottom of the appliance.

Serial

A serial (RS-232) port used for connecting computers in order to access the UTM-1 CLI (Command Line Interface), for using the terminal server, or for connecting an external dialup modem.

An RJ-45 to DB9 converter is supplied for your convenience.

Warning: Do not connect an Ethernet cable to the RJ-45 serial port.

USB

Two USB 2.0 ports used for connecting USB-based printers or modems

RESET

A button used for rebooting the UTM-1 appliance or resetting the UTM-1 appliance to its factory defaults. You need to use a pointed object to press this button.

• Short press. Reboots the UTM-1 appliance
• Long press (10 seconds or until the SYS LED begins to blink rapidly). Resets the UTM-1 appliance to its factory defaults, and resets your firmware to the version that shipped with the UTM-1 appliance. This results in the loss of all security services and passwords and reverting to the factory default firmware. You will have to re-configure your UTM-1 appliance.

Do not reset the unit without consulting your system administrator.

PWR

A power jack used for supplying power to the unit. Connect the supplied power adapter to this jack.
