PC Card slot
This slot (designated as Slot A:) accepts a Type I or II PC Card. It also
supports a DCHIP interface PC Card (D-Chip) to the system through the
NTMF29Bx cable.
Ethernet activity LEDs
The LEDs indicate 100BaseT, 10BaseT, and activity on both the ELAN
and TLAN network interfaces.
Maintenance display
The maintenance display is a 4-character LED-based dot-matrix display. It
displays the IP trunk card boot sequence and displays the card role as
follows:
• LDR = Active Leader
• BLDR = Backup Leader
• FLR = Follower
A properly-functioning IP trunk card displays one of the above codes. If an
IP trunk card encounters a problem, a fault code is displayed. For more
information, see
"Media Card 32-port trunk card faceplate maintenance
display codes" (page 421) and "ITG-Pentium 24-port trunk card faceplate
maintenance display codes" (page 423) .

The Media Card 32-port trunk card has a DIN-8 (RS-232) maintenance port
(DCE) connection on the faceplate and an alternative connection to the
same serial port on the I/O backplane.
CAUTION

Do not connect two maintenance terminals to both the faceplate
and I/O panel serial maintenance port connections at the same
time.

backplane connector:
• DS-30X voice/signalling
• card LAN
