3-6 Operating Instructions

Redundancy Functions

The redundant power supply and the redundant link module ensure the

Optimux-XLT1 operation even when one of these critical modules fails.

Link Redundancy

When the redundant link is installed (backup module and link A) and the link-

redundancy is set to AUTOMATIC from the terminal or SNMP, the Optimux-XLT1

starts using the main link. It will automatically switch to the backup link when the

main link fails (signal loss/sync loss). The LINK A/B SYNC LOSS LED on the front

panel indicates the deactivated link. If the failure is due to signal loss, the

Optimux-XLT1 will switch back to the main link, when the signal is recovered in

the main link. If the failure is due to sync loss, the backup link becomes the active

link until signal loss/sync loss occurs on the backup link.

When the redundant link is installed and the management link-redundancy is

MANUAL, the Optimux-XLT1 starts using the main link. It will automatically switch

to the backup link when the main link fails (signal loss/sync loss). The LINK A/B

SYNC LOSS LED on the front panel indicates the deactivated link. The backup link

remains active even when the main link recovers. Switching back to the main link

is performed by setting the link-redundancy to AUTOMATIC from the terminal or

by turning the system OFF and then ON.

When the management link-redundancy is OFF, the redundancy function is not

available.

Power Supply Redundancy

In the redundant power supply mode, both supplies share the Optimux-XLT1

power consumption. If one of the power supply modules fails, the entire power

consumption of the unit is automatically drawn from a single power supply. In this

case, the respective PWR LED on the front panel indicates the active power

supply.

All changes made to the terminal or SNMP in link redundancy mode at the local site

automatically affect the remote site.

Turn OFF

Set the Optimux-XLT1 rear power switch (switches) to OFF.
