Altigen ACM 6.7 Administrator's Manual page 379

If the board configuration for the default gateway is changed, or the license for the
•
SIP-Trunk is changed, you must reboot both the primary and secondary systems to
make the change take effect. The correct order for reboot is: 1) shut down inactive
system; 2) shut down active system; 3) start active system; 4) start the inactive
system.
• HMCP installed with Softswitch is not supported if VLAN is used. This is because to
run HMCP, VLAN needs one additional NIC but redundancy supports only two NICs.
• If the active system needs to be shut down for maintainance, control must be
manually switched from the active system to the standby system first.
