Form C Normally Closed (NC) contacts to which the user can attach two sets of status
monitoring wires at the green terminal block. When this option is present, the terminal
block for Alarm Contacts is part of the Power Input panel in the Magnum 6K32 case.
The AC or DC power input connection is in the same panel. A manual On-Off Switch for
power to the unit is not available on 6K32 units with the Alarm Contacts option, as these
two features occupy the same space in the case.
The first NC Alarm Contact (top position) is a “Software Alarm”, 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 S-Ring Fault, causes the contact to open and thus trigger an
alarm in the user’s monitoring system
The second (bottom position) NC Alarm Contact is held close when there is
power on the main board inside of the 6K32. This provides a “Hardware Alarm” because
the NC contacts will open when internal power is lost, either from an external power
down condition or by the failure of the power supply inside of the Magnum 6K32
Switch. Useful info. about Alarm contacts:
1. There is four terminal block (1,2,3,4)provided next to AC/DC power supply
2. The top two pins (1,2) are software operated
3. The bottom two pins (3,4) are hardware operated
4. By default it is NC (normally closed)
5. The software operation need to be enable and set to get the Alarm traps. For detail
information about the Software Alarm and software control of SNMP alarm traps, please
reference the Magnum MNS-6K Software User Manual. (Chapter 19th).
3.5 6K32 Port Module (6KPM) Installation
The Magnum 6K32 Switches are normally received from the factory with 24
ports fixed and one required 6KPM modules installed. There may be situations where
6KPM cards need to be added or replaced. In cases where a 6KPM module is desired to
add in the modular slot, the faceplate for an available front-mounted slot must be
removed. The following procedure describes this operation.
3.5.1 Preparation for Installing and Removing 6KPMs
STOP!!!
Be sure the power cord is unplugged
from the chassis before attempting to remove
and/or replace any PM cards.
Failure to do so may result in damage to the unit
and will void the warranty.
