Alarm Contacts for monitoring internal power and Software Traps

The Alarm Contacts feature, standard on the Magnum 10KG, provides two
Form C Normally Closed (NC) contacts to which the user can attach two sets of status
monitoring wires at the Alarms terminal block, see Fig 3.5a below.
The first NC Alarm Contact is a "Software Alarm" (labeled S/W), operated by
user settings in the MNS-6K software. The user can disable the Software Alarm feature
with a software configuration command if desired. When the Software Alarm is enabled,
the Form C Normally Closed (NC) contact is held close during normal software
operation. A user-defined software malfunction, such as an SNMP Trap or a Software
Security violation or an RSTP Fault, causes the contact to open and thus triggers an alarm
in the user's monitoring system.
The second NC Alarm Contact is held closed when there is power on the main
board inside of the Switch. This provides a "Hardware Alarm" (labeled H/W) because the
NC contacts will open when internal power is lost, either from an external power down
condition or (if not a Hot-Swappable Power Supplies switch unit) by the failure of the
power supply inside of the Magnum Switch.
Useful information about the Alarm contacts:
1. There are four terminal contacts (1,2,3,4) provided next to the power input.
2. The left two pins (1,2) are hardware controlled.
3. The right two pins (3,4) are software controlled.
4. These are both NC (normally closed) relays.
5. The switch's software operation needs to be enabled and set to get the Alarm traps. For
detailed information about the Software Alarm and software control of SNMP alarm
traps, please reference the Magnum MNS-6K Software User Manual.
