HRR 4104 Alarms

The HRR 4104 provides alarms relating to the module as a whole, as well as
alarms within the specific receivers (A through D). Table 3-2 describes the
alarms for the HRR 4104 Return Path Receiver.
When there is an alarm, the Status LED on the front panel of the HRR 4104
module illuminates red. In addition, every alarm is reported via SNMP and
via the HLP 4200WD front panel display. For information on accessing the
alarms via the HLP 4200WD front panel display, see Section 3.1.
