REDUNDCY Redundancy enable.
In order to enable a redundant system, the redundancy control must be
switched to "YES". "YES" forces the KST to become aware that another KST
needs to be considered for backup situations when faults occur.
Note: If the redundancy interconnect cable is not connected, a "CABLE NA"
message will be displayed. Further redundant configuration is not possible
until the cable is connected.
BACKMODE Sets the backup mode
Options: MANUAL (default) forces the unit to switch from an OFFLINE mode
to an ONLINE mode regardless of what the other is doing.
Auto-dependent (AUTO-DEP) forces the unit to automatically switch from an
OFFLINE mode to an ONLINE mode depending upon whether or not a fault
has occurred in the other unit. It forces the unit to relinquish control of both
the UL and DL when a fault occurs on either link. The other unit will pick up
control of both the UL and DL when this occurs.
Auto-independent (AUTO-IND) forces the unit to automatically switch from an
OFFLINE mode to an ONLINE mode depending upon whether or not a fault
occurred in the other unit. It forces the unit to independently relinquish control
of either the UL or DL when a fault occurs in that specific link. When a fault
occurs on a link for one unit the other unit will pick up control of that specific
link.
M SWITCH Backup Manual Operation
Options: DLUL, DL, UL
DLUL: forces the unit to make the DL and UL ONLINE.
DL: forces the unit to make the DL ONLINE and UL OFFLINE.
UL: forces the unit to make the UL ONLINE and DL OFFLINE.
Note: This menu option is only displayed if the BACKMODE (above) menu
selection is set to MANUAL.
BKSTATUS Backup Status
Real time display of the UL and DL status: ONLINE or OFFLINE where
OFFLINE indicates the specific link that is not under the influence of the
machine that reported this status.
Note: Due to display limits, the UL and DL status will alternate status every
second.
