Chapter 47: Qpc841 Quad Serial Data Interface Card - Avaya Nortel Communication Server 1000 Reference

QPC841 Quad Serial Data Interface card
• NT8D35 Network module (slots 5 through 13)
• NT9D11 Core/Network module (slots 0 through 8)
Note:
When a QSDI card is installed in an NT6D60 Core module, an NT8D34 CPU module, or slot
13 of an NT6D39 CPU/Network module in a dual-CPU system, any input/output I/O device
connected to the card does not function when the CPU in that module is inactive.
Physical description
The QPC841 QSDI card is a printed circuit board measuring 31.75 cm by 25.4 cm (12.5 in. by
10 in.). The front panel is 2.54 cm (1 in.) thick. See
panel on page 679.
Up to four QSDI boards can be used in a system, allowing a total of sixteen asynchronous
serial ports. The four serial ports on each card are addressed as two pairs of consecutive
addresses (0 and 1, 2 and 3, and so on up to 14 and 15). The pairs need not be consecutive.
For example: pairs 0 and 1, and 4 and 5 could be used.
The card front panel has two connectors, J1 and J2. Connector J1 is used for port 1 while
connector J2 is used for ports 2, 3, and 4. It also has an Enable/Disable (ENB/DIS) switch and
a red LED. The LED indicates that the card is disabled. It is lit when the following occurs:
• the ENB/DIS switch is set to DIS
• all of the ports on the card are disabled in software
• none of the card ports are configured in software
