DOCSIS CMTS Resource Module LEDs
The DOCSIS CMTS Module has two groups of LEDs that indicate its operational
status:
• Module LEDs
• Per-Port LEDs
The following subsections describe the possible display states of these LED types.
Module LEDs
The DOCSIS CMTS Module LEDs are visible on the module front panel and are
labeled: Fail, Status, and Alarm.
Table Table 2-4 describes the possible display states of these LEDs during
operation.
Per-Port LEDs
The DOCSIS CMTS downstream port and each upstream port have two LEDs to
indicate their operational status. These LEDs are visible on the module front panel
and are labeled Link and Fail.
