5.4 Upgrading withinTCP/IP
To use the FTP based method of FLASH upgrade, it is first necessary to
establish an FTP connection to the Print Server in the same way as that
used when printing to the unit via FTP. Typically this will be achieved as
follows:
FTP xx.xx.xx.xx
where
xx.xx.xx.xx is the unit’s Internet Address
Once connection is achieved in this way, the Print Server will
respond with a prompt requesting the USER NAME to be supplied.
When printing to the unit, this field may be ignored but when preparing
to perform a FLASH upgrade, it is the response to this field that
indicates an upgrade is being performed. To continue with the upgrade
procedure, the user must enter:
pattonflashupdate
followed by carriage return. It is now necessary to transmit the new
operating system to the Print Server. The units new operating system
will be supplied on a single 3.5 inch diskette which will contain a single
file called IMAGEnnn.BIN (where nnn is the version number of the
upgrade). This file is typically transmitted to the Print Server using the
PUT command as shown below:
PUT IMAGE.BIN
Assuming that the file transfer was completed correctly, the Print Server
will respond to the end of transfer with the message:
FILE TRANSFER COMPLETE - Upgrade continues when FTP is quit
Quitting FTP will now cause the FLASH upgrade to occur, and after a
few seconds, the unit will reboot and begin operating using the newly
downloaded operating system.
5.5 Troubleshooting within TCP/IP
The following hints should help you if trouble arises when using the
Print Server. If you experience additional problems, contact Patton
Technical Support M-F, 8:30 - 5:00 PM EST at (301) 975-1007.
General
No Power LED
1) Check that external power supply adapter is correct type and is
functioning correctly.
2) Ensure DC connector to the Print Server is seated correctly.
3) If you are relying only upon interface power on pin 18 of the
Centronics interface, be sure the output is 5 V DC (TTL Spec.).
Status Page Not Printed
1) The status page prints only within 30 seconds of power-up or when
forced by software (see Section 5.2.1)
2) The power-on status page option may be disabled (see Section
5.2.1)
3) The Postscript printer option may be set incorrectly for your printer
(see Section 5.2.1)
4) Your printer may have a large internal buffer, in which case the
status page may have spooled to your printer but is waiting for a
timeout or command in order to print. (Check your Printer manual.)
TCP/IP Specific
Print Server Will Not Respond To PING
1) Ensure the units Internet Address has been correctly set
Check the hosts ARP table is correct

Warning! Do NOT remove power while the timeout message is
displayed! Only after the timeout message disappears is it safe to
remove power from the Print Server.
