553-3001-202 Standard 1.00 April 2000
Card Status LED
A single red, card status LED on the faceplate indicates the enabled/disabled
status of the 24 ports on the card. The LED is on (red) during the power up or
reset sequence. The LED remains lit until the card correctly boots and
assumes its role (that is, Leader, Backup Leader, Follower or DCHIP). If the
LED remains on, one of the following has occurred:
• that self-test has failed (the Faceplate Maintenance Display indicates the
cause F:xx)
• the card has rebooted
• the card is active, but there are no trunks configured on it (for example,
the card is a Leader or DCHIP)
• the card is active and has trunks, but the trunks are disabled (that is, the
trunks must be enabled in LD 32)
Note: During configuration, the error message “F:10” can appear. This
error indicates a missing Security Device. It occurs since Security
Devices are not implemented on ITG Trunk 2.0. You can ignore this
message.
See “ITG Trunk 2.0 faceplate maintenance display codes” on page 329 for a
complete list of faceplate codes.
Ethernet status LEDs
Ethernet status LEDs for the voice interface on the daughterboard display the
Ethernet activity as follows:
• Green is always on if the carrier (link pulse) is received from the T-LAN
Ethernet hub.
• Yellow flashes when there is data activity on the T-LAN.
• During heavy traffic, yellow can stay continuously lit.
Note: There are no Ethernet status LEDs for the management interface
on the motherboard.
