Dedicated Service LAN
•
Connect one G4SA to each maintenance switch.
This illustration shows a fault-tolerant LAN configuration with two maintenance
switches:
Caution. To avoid possible conflicts on the LAN:
•
If the configuration includes two maintenance switches, install and configure one switch
completely, including assigning its IP address, before you install the other.
•
Only one connection between the maintenance switches is permitted. More than one
connection overloads network traffic, rendering the dedicated service LAN unusable.
•
If ServerNet switch boards in the IOAM enclosure will have static IP addresses, configure
one completely, including assigning the IP address, before you configure the other.
