be configured as Leader 1 even though it has no Leader functions.
The remaining cards are configured as Followers.
b. Management IP: If changing the Management IP address of
Leader 0, it is necessary Telnet to the card and use the setLeader
command to make the same change (new Management IP address)
in the NVRAM of the Leader 0 card.
Leader 0 must be reset for OTM to resume communication with the
node.
Note: Before resetting Leader 0, unplug all the other cards to prevent
any other card from becoming the Master. When Leader 0 restarts, plug
the cards back in. These other cards receive their new configuration from
Leader 0.
c. Management MAC: All other IP configuration depends on the
accurate configuration of the Management MAC address. The MAC
address is located on the faceplate of the Voice Gateway Media Card
and is labelled as MOTHERBOARD Ethernet address. The
Management MAC address corresponds to the ELAN network
interface address.
d. Voice IP: This is the card Voice IP address. This address is also
known as the card TLAN network interface IP address. In an IP
Telephony node, all cards must be assigned an address on the same
TLAN subnet. The card Voice IP address must be distinct from the
node IP address.
e. Voice LAN gateway IP: All cards in the IP Telephony node must be
on the TLAN subnet; therefore they all share the same Voice LAN
(TLAN) gateway IP address.
f. Card TN: The Card TN format must match both the machine type
and the card slot where the card resides. Otherwise, the voice
gateway channels do not function.
If trying to change the card TN format, first record the node
configuration data. Delete the node. Change the card TN format to
the correct machine, and rebuild the node.
For Large Systems, enter Card TN (l s c) information. For Small
Systems, enter only the card slot number between 1 – 50. The card
TN format is determined by the system type which is configured in the
OTM navigator. The correct system type must be entered in the OTM
Navigator before adding the node.
