2. Observe the LEDs on the SRM on the BSR 64000 or the front panel of the
BSR 1000 to determine if there is a fail condition or alarm.
• If there is a fail condition and the SRM circuitry is not receiving power,
replace the SRM on the BSR 64000.
• If there is an alarm condition, check the modules on the BSR 64000 to
determine which one is faulty.
• If there is a fail condition on a BSR 1000, replace it.
• If there is an alarm condition on a BSR 1000, troubleshoot the faulty port.
3. Observe the LEDs on the faulty module of the BSR 64000 to determine if
there is a fail condition or alarm.
• If there is a fail condition and the module’s circuitry is not receiving
power, replace the module.
• If there is an alarm condition, check the port interfaces to determine which
ones are faulty. The solution may require that you swap the module with a
new one, or troubleshoot the faulty port.
SRM LEDs
The SRM has the following groups of LEDs that indicate its operational status and
the status of other chassis components. The subsections that follow describe the
display states of these LED groups:
• Module LEDs
• Fan Status LEDs
• Alarm LEDs
Module LEDs
The DOCSIS CMTS Module LEDs are visible on the module front panel and are
labeled: Fail, Status, and Alarm.
