Activate the ring manager for this device. Do not activate the ring
manager for any other device in the Fast HIPER-Ring.
Activate the function in the “Operation” frame.
Leave the VLAN ID as 0 in the VLAN field.
In the “Switches” frame, enter the number of Switches in the ring in
“Number”. This entry is used to optimize the reconfiguration time and
the stability of the ring.
Click on “Set” to temporarily save the entry in the configuration.
The display in the “Ring Information” frame means:
– Round Trip Delay: Round trip delay in µs for test packets, measured
by ring manager.
Display begins with 100 µs, in steps of 100 µs. Values of 1000 µs
and greater indicate that the stability of the ring is in danger. In this
case, check that the entry for the number of Switches in the
“Switches” frame is correct.
The displays in the “Information” frame mean
– “Redundancy existing”: One of the lines affected by the function can
fail, whereby the redundant line will then take over the function of the
failed line.
– “Configuration failure”: The function is incorrectly configured or there
is an error in the ring port connection.
