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 "Set" to save the changes temporarily.
The display in the "Ring Information" frame means:
– Round Trip Delay: round-trip delay in µs for test packets, measured
by the ring manager.
Display begins with 100 µs, in steps of 100 µs. Values of 1000 µs
and greater indicate that the ring may become unstable. In this case,
check that the entry for the number of Switches in the "Switches"
frame is correct.
