Power and Network connections.  Connect your PBX server to a standard AC power source.  Some Protel-LTS models are supplied with a power adapter, others connect directly to a power connector on the back of the unit.  Using a standard Ethernet cable (not supplied), connect the PBX to a network router that has open access to the internet, and is configured to dynamically assign a local IP address to any device that requests it (DHCP).  If your PBX has more than one network port, use Port #1 (left side, looking at the connection panel).  There should also be a label on the back panel to confirm which port to use.

Power up the PBX.  For Protel-LTS wall/shelf-mount units (models 2106 and 3510), the power switch is activated by inserting a paper clip or similar tool into the recessed hole next to the  symbol.  Press firmly for 1 second, then release.  The power LED light will come on to confirm that the PBX is booting up.  For rack-mount PBX models, momentarily press the power button on the front panel of the unit.

Determine the PBX IP address.  Unless specified otherwise, your PBX is shipped in DHCP mode, meaning that the PBX NIC (Network Interface Card) will request a dynamic IP address from your router.  You have 2 options for determining what address your router assigns to it.  If you have the login credentials for your router, the easiest method is option A.  The alternative is to use option B, which requires that you have a USB keyboard and a video monitor connected directly to the PBX.

NOTE:  If your network only allows static IP connections, you will need to manually set a static IP address in the PBX using Linux command line.  Follow the instructions here

Option A:  Find the PBX IP address in the router.  You will need to use a computer that is connected to the same router that the PBX is on.  Log into the router through an internet browser on your PC, and find the administration page that displays a list of the connected DHCP devices.  Locate the PBX, either from its SSID of Protel-LTS-XXXX, or from its MAC address listed in the device table, and note the assigned LAN address.

Option B: Use Linux command line to display the IP address.  You will need to have a standard USB keyboard connected to any USB port on the PBX, and a video monitor with the appropriate connecting cable.  Depending on the model of PBX, the video connection could be VGA, DVI or HDMI.  You do not need to have a mouse connected.  When the monitor is connected and the PBX has booted up, you should see a login prompt.  If your monitor screen is blank, you may need to reboot the PBX with the monitor connected so that the server can detect the display.  Press the  button to reboot.  If your monitor is connected properly, you will see the motherboard splash screen, followed by many lines of text scrolling by, and finally, the login prompt.  type pbxadmin then press Enter.  Type the password provided with your unit, then press Enter.  Linux does not display your password entry, so you will need to type carefully.  When you are logged in, type ifconfig then press Enter.  The current LAN address will be displayed.

If you cannot log in via a web browser and you need to change the network settings on the PBX, follow the instructions here.
