Shelf Alarms Menu

In the Config menu, press H to display the Shelf Alarms menu (Figure 3-10). This menu allows you to enable, disable, and set the severity of the loss of shelf power, HDSL/G.SHDSL lines down, and loss of external clock alarm.

The Config menu also allows you to configure how each of the alarm relays respond to an ACO (Alarm Cut-Off). The ACO can be activated from the EMU-830 front panel pushbutton or by connecting to ground the EXT (external) ACO pin on the EMS-83x shelf's alarm connector. Selecting Enable (ENA) causes the associated alarm relay to be retired (common contact connected to normally closed contact) when an ACO is received.
