Replace a Voice Gateway Media Card

Replace the Voice Gateway Media Card when the card is removed or when

the following conditions occur:

• The Voice Gateway Media Card displays a code of the form F:xx on the

faceplate LED following a reboot. This code indicates an unrecoverable

hardware failure. The card cannot register with the system. The

exception is the F:10 code, which indicates that the Security Device is

missing from the card.

• The Management (ELAN) network interface or the Voice (TLAN)

network interface on the Voice Gateway Media Card has failed. This is

indicated by failing to show a link pulse on the voice IP interface status

LED or on the switch. It can also be indicated if the maintenance port

continuously prints ‘lnIsa0 Carrier Failure’ messages after determining

that the hub or switch port and ELAN cable are good.

• A voice channel on the Voice Gateway Media Card has a consistent

voice quality fault, such as persistent noise or lack of voice path, even

after resetting the card and re-transmitting the card properties.

Note that there are separate procedures for replacing a Voice Gateway Media

Card, depending on the role it is to play. Be aware of the role the card will

perform and choose the correct procedure. To replace a Follower card, see

“Replace a Follower Voice Gateway Media Card” on page 772. To replace a

Leader card, see “Replace a Leader Voice Gateway Media Card” on
