problems may occur when upgrading Microplex

- When you
enter "upgrade" on the unit to
put the server into upgrade mode, the
server hangs instead of rebooting itself.

- This error
can occur after you enter the
"boot" command on the unit and
means the server isn't in upgrade

upgrade step which tells you how to put
the unit into upgrade mode.

you're in upgrade mode when you

possibility that the flash PROM has been

|The majority of
the time you run in to upgrade problems, the
cause is related to a TFTP error which gets
reported back to your TFTP host. These error
reports are very helpful and may include:
"Remote Host Not
- This message
will occur after the "boot"
command has been issued on the server and
right when the server begins looking for
the remote host (i.e. the TFTP server)
which has the download and firmware
binary files stored on it.
- If you get
this error, you should confirm that you
have the TFTP daemon running on this host
and that you've specified the correct IP
address for this TFTP server in the
"boot" command on the unit.
make sure the TFTP daemon is
running on your Unix host,
confirm the TFTP line is
uncommented in the
and then try restarting the INET
the process ID of this daemon
(e.g. "ps -aux | grep
inetd") and then restart
this ID using "kill -HUP process
you are using a PC as a
TFTP server, make sure you have
taken the appropriate steps to
activate the TFTP service based
on the TCP/IP software
this error refers to upgrade files that
are not accessible due to incorrect
- Please make
sure your upgrade files have global read
permissions so the server can access
"IP address not
- This error
might occur if you're using the download
file with the last line starting with
something like "C205-DLTFTP
5.4.1" and you're upgrading to a
firmware level like 5.6.x or higher.
- It is due to
a bug in the download file itself but
this can be easily fixed by simply
pinging the unit's IP address from the
host when this error comes up. This
reminds the server of its IP address and
allows the upgrade process to continue.
- If that
doesn't help, you may have to try issuing
a new ARP entry on the host to update the
entry for this unit in your host's ARP
table. This can be done with;
-s product_IPaddress product_Ethernetaddress".
- You'll see
this error if you've mistakenly tried to
use a download or server binary file with
a product model that does not match this
- For example,
if you're upgrading an M205 print server,
both upgrade files (i.e. m205_dl.hex and
m205.hex) should have last lines starting
with "C205..." indicating that
these files are okay to use with M205s
and M206s. They will not work with any
other models except the M205s and M206s
and this TFTP error warns you of this.
- This error
will come up if either the download or
firmware binary file is missing the
security line found at the bottom of each
file (e.g. "C205-ROM 5.6
- If you come
across this error, you should:
the ends of both upgrade files to
see which one is missing the
the original of whichever file is
missing this information from
Microplex's FTP site or from
that this original has the
security line at the bottom.
the "bad" file with
this new one and try the upgrade
- If this error
comes up, it points to either upgrade
file but most likely the firmware binary
file (e.g. m205.hex).
- It tells you
that this file may be corrupt or has had
something done to it to make it differ
from the original.
- The quickest
solution is to grab this file (or both)
from Microplex's FTP site again (if
possible) and then try the upgrade again.
- If you've got
the upgrade files on diskette, you should
compare sizes between the file you have
in your TFTP directory and the file on
diskette and if there's a difference,
take a new copy of the original and put
this into your TFTP directory.
- If the sizes
are identical, you may want to contact Microplex for help.
Upgrade process takes
a very long time
- The only
other problem that can arise is the
upgrade process takes a very long time
and you seem to be waiting forever.
- Normally this
happens because the unit cannot find the
firmware binary file on the TFTP host. If
this happens you should check;
TFTP setup and make sure your
upgrade files are sitting in the
firmware binary file's
permissions, they should have global
any TFTP errors that are reported
back to the TFTP server.
- If you find
you are waiting for more than 30 minutes,
you can reboot the unit and see if the
ERR LED comes on and stays on. If so;
see the point under "Microplex
relating to the ERR LED.
likely you will be able to reboot
this and try the upgrade again
but only after you've confirmed
all setup steps.
|Product Specific Errors
Putting unit into upgrade
mode causes hardware panic
- Sometimes the
M208 might go into hardware exception
(i.e. ERR LED comes on and it won't go
away) once it's put into upgrade mode.
- Resetting the
unit again will take the unit out of
upgrade mode and fix the problem,
however, to go ahead with the upgrade
procedure, you will need to leave the
M208 turned off for a while to let it
- Then you can
try the process again.
- This will
only happen if you use the v5.4.1
downloader file, with the last line
starting with "C208-DLTFTP
- Other, newer
versions of the downloader file should
not cause this problem.

than the other Microplex product models due to
slower processors. It should take about 15
