Mocomtech CRS-300 operation manual Config Options Æ ALARM-MASK

CRS-300 1:10 Redundancy Switch	Revision 16
Front Panel Operation	MN/CRS300.IOM

CONFIG: OPTIONS Æ ALARM-MASK

If ALARM-MASKis selected:

ALARM MASK: MODEM-ALARMS

SW-ALARMS AUDIO (ENTER)

Select MODEM-ALARMS, SW-ALARMS, or AUDIO, then press [ENT]. The Switch logs and reacts to both its own faults and modem faults. Either type of faults may be masked using this submenu. In addition, an audible buzzer can be enabled as an additional indicator.

CONFIG: OPTIONS Æ ALARM-MASK Æ MODEM-ALARMS

If MODEM-ALARMSis selected:

MODEM ALARM MASK:	NONE
TX RX TX+RX	(ENTER)

Select NONE, TX, RX, or TX+RX, then press [ENT].

The User may mask Transmit or Receive Traffic faults (or both) from being reacted to by the Switch. This not only prevents the Switch from performing Auto mode functions when these modem faults are sensed, but also keeps the faults from being logged by the Switch.

NOTE: These selections are global to all the modems. If masking of individual modem faults is desired, it should be done directly on the modem. Unmasked modem faults are logged on active modems only.

CONFIG: OPTIONS Æ ALARM-MASK Æ SW-ALARMS

If SW-ALARMSis selected:

SWITCH ALARM MASK: NONE ËPSU-A PSU-BÌ(ENTER)

Select ËPSU-Aor PSU-BÌ,then press [ENT].

The User may select which, if either, of the plug-in power supply units needs to masked. Only one of the units can be masked at a time. Normally this would be done if the User wishes to run with only one supply, or if a bad supply had been removed for service or replacement.

CONFIG: OPTIONS Æ ALARM-MASK Æ AUDIO

If AUDIO is selected:

AUDIO MASK: NONE SW-ALMS

MODEM-ALMS BOTH (ENTER)

Select NONE, SW-ALMS, MODEM-ALMS, or BOTH, then press [ENT].

For all Switch or modem alarms that are unmasked, the User may select which alarm types should force the Switch to react with an audible buzzer located behind the front panel. In addition, a relay closure to ground activates on pin 20 of the System Alarms connector so that the User may attach other indicators.
