Problem/ Condition

Possible Interpretations

What to do

A card appears to be “stuck” on

the old revision of firmware.

 Firmware bug makes a small

number of cards use the wrong IP

address for software update requests.

 Refer to Section 7 and check for errors in

upgrade settings.

 Look for an address like 169.255.7.xxx in

the TFTP logs. If found, temporarily remap

the PC’s IP address to a matching subnet.

When attempting to upgrade a

full chassis, the last couple of

cards do not upgrade.

 If there are more than six cards in a

chassis, the first card will get to the

reset stage before the last six cards

receive the upgrade request.

 Refer to Section 7 and check for errors in

upgrade settings.

 Initiate the upgrades from the highest-

numbered slot in the chassis.

Cards cannot be upgraded

when using the integrated

switch of a COM200 chassis.

 This is due to a limitation in the

initial production run of the COM46

cards; it is only an issue when these

cards are placed in a COM200

chassis.

 Refer to Section 7 and check for errors in

upgrade settings.

 Connect the cards; front Ethernet ports to

an external switch and upgrade in the same

manner as with a COM100 chassis.

Cannot talk to / find cards.

 Possible IP routing problems on PC.

 Possible Ethernet cable / port

problems.

 Disable wireless interface on PC and try

again.

 Try switching around Ethernet cables /

ports.

Video quality is severely

degraded when using an IP-

only distribution system.

 External switches in the network are

FE only or misconfigured

 In such an installation, an external GbE

switch will be required.
