Blinks 3 Times, Then Pauses
The POWER LED indicator blinks 3 times, pauses, then repeats. This is equivalent to
the PR.xx LED code that appears on the front panel of alphanumeric LED DHCTs.
This message indicates that the DHCT is receiving new software. This is normal
behavior. Do not reboot the DHCT or remove power.
The PR.xx condition can take 15 to 30 minutes to clear if the software download is
interrupted.
Important: If you interrupt the DHCT in its download process, the DHCT could be
damaged and will have to be replaced. If the DHCT does not update its software
after 30 minutes, notify your supervisor or headend manager. The DHCT may have
an RF issue or a download issue. Follow your company's escalation procedure.
Blinks 4 Times, Pauses, Repeats Only Once
The POWER LED indicator blinks 4 times, pauses, and repeats only once. This
indicates that you have activated the Staging Toolkit.
This is normal behavior and is given so you know when the Staging Toolkit is ready
for further instructions. Refer to Staging Toolkit (on page 165) for more information.
Blinks 5 Times Slowly, Pauses, Repeats
The POWER LED indicator blinks 5 times slowly, pauses then repeats. This indicates
that the DHCT has no stranded IPPV events.
Important: This behavior only appears when you activate the Staging Toolkit and
check for stranded IPPV events. Refer to Staging Toolkit (on page 165) for more
information.
