You can use the hardware restore button on the Polycom HDX system to reset
the system in one of these ways:
• Restoring configuration-Restores the configuration, which resets most
system settings to default values.

• Factory restore-Completely erases the system and restores it to the
software version and default configuration stored in its factory partition.
If you follow this procedure while a USB storage device is connected, the
system restores from the USB device instead of the system's factory
partition.
The restore button is on the front of the Polycom HDX 9000 series system, as
shown in the following figure.

Verify the uplink / download bandwidthon the broadband link.Broadband link do not have symmetrical upstream/downstream speeds. Perform test to verify.
Try non-peak hrs.
Check if latency is consistent.

no you don't.

Try reseting the camera, power it down, wait 30 seconds then power it back up again.

no the power supply is propreitory( has multiple voltages) & is not advisable, u could blow up ur expensive confeencing equipemt.polycom has designed it in that manner!!

The polycom didn't allow for numbers, only letters.....
How do I do password recovery in this case?

this looks like a power issue.replace/repair the power adapter before u send it for repairs to POLYCOM, they will charge u a BOMB
