Installation and Maintenance Manual v4/0615/10
The loader will only be upgraded if a newer version is detected. However, if you wish the loader to be
upgraded nonetheless you can enter:
upgrade loader <IP address of Call Server> force
eg upgrade loader 192.168.0.1 force
Please note: If the Phone Module is a DHCP client -
The Phone module has its operational software stored in flash memory. When upgrading this software as
above the module does its usual DHCP request for an IP address BUT it also looks in the DHCP response
for Option 66 “Boot Server Host Name” to find out the location of the software. The Phone Module then
does
a TFTP request to that server for the “potsmod.img” file. If it does not see that option within the
DHCP response the module will not come back up as it has already erased the original software.
When the Call Server acts as the DHCP server it gives out the required fields. A Windows 2000 DHCP
server can also give out this DHCP option either in general or to specific MAC addresses, but only if
option 67 “Boot file name” is also specified. The configured file name is not important to the
Phone Module so use any name, eg frog.txt.
In summary, it is important that the DHCP server has option 66 (and 67, if necessary) pointing to the
Call Server otherwise the Phone module software upgrades will fail.
Upgrading an IP Phone
Software upgrades will be supplied as a file such as
pcs580.3.3.102.tar.gz (for the PCS 580)
pcs5x1.3.3.102.tar.gz (for the PCS 572, PCS 562 and PCS 55x)
pcs54x.3.3.102.tar.gz (for the PCS 542)
pcs5xx.3.3.102.tar.gz (for the PCS 560 and 570)
The patch file must be renamed before proceeding to the next stage.
x
Edit the file name to remove the version number so that the files are called, eg pcs410.tar.gz
x
If after downloading the file the name of the file has changed to, eg cs5100.patch.3.2.879.tar.tar,
rename the file to change the final .tar to .gz.
