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.
