Replacing an IP Line card

553-3001-119 Standard 2.00 April 2000
Maintenance
The IP Line card should be replaced when the following conditions occur:
• If, following a reboot, the IP Line card displays a code of the form
"F:xx" on the faceplate LED display, this indicates an unrecoverable
hardware failure and the card will not register with the Meridian 1.
The exception is the "F:10" code, which may indicate that the
Security Device is missing from the card.
• If the management Ethernet interface or the voice Ethernet interface
on the IP Line card has failed. This may be indicated by failure to
show a link pulse on the voice IP interface status LED, or on the hub,
or if the maintenance port continuously prints 'lnIsa0 Carrier
Failure' messages, after proving that the hub port and T-LAN cable
are good.
• If a voice channel on the IP Line card has a consistent voice quality
fault, such as persistent noise or lack of voice path, even after
resetting the card and retransmitting the card properties.
• Or, If the card cannot detect a known good Security Device.
The card should first be removed for 2-3 seconds and then reseated in the IPE
shelf in order to perform a power-on reset. If the failure persists, there is no
option but to replace the card. Use the following procedure to replace a faulty
