• WARNING:Digi specify implicitly that power to the PortServer should be switched on by it's own on/off switch located on the side of the box. This is to prevent voltage transcients and spikes from the external psu corrupting the memory.
• The PortServer can be initially configured from "Port 1" using a suitable cable connected to a VT100 compatible device. The settings should be :
  9600 baud 8 bit No Parity 1 stop bit.
  This port setting should not under normal circumstances be changed. It is also the port where messages are sent indicating the state of health/status of the Portserver. If it is necessary to change these settings, mark up which port has been changed and what the data configuration has been set to.
• Port 16 is generally reserved for loop back testing. A special test plug with TX/RX shorted is normally fitted in this position, but it can be moved across to any other channel for loop back tests.
• NOTE: Portservers 1 and 2 are fitted into 2U 19" trays to allow for easy mounting. However, only PortServer 1 (located in the INT Clip Centre) has all sixteen RS232 ports available at the front panel.

Portserver 2 (fitted in the CCDC rack on the INT Cass rotator) only brings out to the front panel of the tray Ports 9 through to 16. These are reserved for Cass instrumentation.

Ports 1 through to 8 are reserved for the Prime Focus WFC RS232 connections. Those of the eight which are used plug directly into the RJ45 sockets and are hardwired to a 55way connector on the rear of the PortServer tray. To gain access to ports 1 to 8 for loop back tests etc, the tray needs to be removed from the rack on the telescope and the lid taken off.

Resetting the PortServer to factory default settings.

• This will remove ALL installed settings. You should only do this if you have found that you have no access to the PortServer over the network or when using Port 1 (or an alternate control port if this has been changed). If you forget the password then an initialisation will be required at some point.
• CAUTION:  Turn off the PortServer's power switch. Press and hold both "arrow" pushbuttons (located on front of PortServer) at the same time and turn on the power switch. Hold the buttons in until the display reads EP (stands for EEPROM Program). The default root password will default to dbps and Port 1 will become the default control port for access.
• When initially switched on using the PortServer's own on/off switch, it will execute a Power On Self Test (POST). On completion, if no errors are detected, the 7 segment LED display should end up displaying AC and the ten LEDs will each go on in sequence.
• If you have reset the PortServer to the factory default settings, you will need to connect to the PortServer via a terminal set to 9600 8 Bits No Parity 1 Stop Bit and setup the IP address as follows:

• Press the return key and you should get a User prompt Login: Log in as username root and password dbps. Enter the IP address with the command: set config ip=161.72.6.136 or whatever the IP address is from the table below then type exit.

• You can now log on to the PortServer using any available machine and telnet to complete the configuration.

user@scorpio> telnet portserver1
Trying 161.72.6.136...
login: root
passwd: dbps

Now you must enter the following commands. The easiest way is to open a telnet session to the PortServer in one window and then using the mouse, cut the commands from below and paste them into the telnet session.

set config submask=255.255.255.0
set config domain=ing.iac.es
set config gateway=161.72.6.1
set config nameserv=161.72.6.232
set config realport=771

set ports range=* termtype="vt100" dev=prn sess=4 uid=0 edelay=1

set logins message=2:"PortServer 16" range=*
snmp run=on auth_trap=off
snmp trap_dest=161.72.26.18
snmp location=""
snmp contact="Don Carlos Abrams"

Now you can exit if you choose or review the configuration. e.g.

cpconf term
exit

At this point you should confirm that the PortServer completes its power-on self test. All being well, the PortServer is now ready for operation. Good Luck...
