The power interface card must be fully seated and the screws must be tight for proper operation. Connecting Input Devices to the Controller Card There are two choices of input devices for the Smart 16 controller card: a VT100 terminal or the optional DATAMATE (part number 1200045L1). 26 Smart 16 Shelf User Manual 64202023L1-1 VT 100 Connection The 25-pin EIA-232 connector (labelled DTE/DCE EIA 232) on the rear power interface of the controller card provides an interface for an asynchronous ASCII VT 100 terminal, used for both local and remote configuration. The terminal must be set to line wrap off, flow control off, and VT 100 mode. The controller card settings are as follows: autobauds from 2400 to 19.2 kbps baud rate, 8-bit character size, no parity, and one stop bit. For remote configuration, see the section Modem Connection. The pin assignments for the EIA-232 connector are listed in Appendix A, Pinouts on page 55. Modem Connection The Smart 16 Shelf and any rackmount units in the shelf can be configured remotely using a modem. See Chapter 3, Operation on page 35 for more detailed information on remote operation. DATAMATE Connection The optional DATAMATE is a hand-held device that plugs into the RJ-11 jack on the front of the controller card, or the RJ-11 jack at the top of the rear PWR/ CTRL segment. Multi-Shelf Connection (Daisy Chaining) For multi-shelf applications, the control port is daisy-chained through the two six-pin modular jacks labelled CTRL LINK. Cabling of a multi-shelf system is detailed in Chapter 3, Operation on page 35. This application requires a straight-through cable. If problems arise with the operation of one of the shelves in the chain, the malfunctioning shelf will be bypassed so that the chain will not be broken. See Appendix A, Pinouts on page 55 for the pin assignments for the CTRL IN and CTRL OUT connectors. Alarm Connections The terminal strips located on the back of the Smart 16 Shelf controller card are labeled ALARM. They are used for audio or visual alarm indicators provided by the user. The top two terminals are a set and the bottom two are a set. The terminals are activated together when the cards inserted in the designated slots encounter an alarm condition such as primary link failure. 64202023L1-1 Smart 16 Shelf User Manual 27 To verify operation of the terminal strip, measure the impedance across each set. The impedance should be open when the shelf is not in alarm and shorted (approximately 0.6 ohm) when in alarm. The two alarm sets operate identically and should have the same impedance. The power specifications for any alarms used are NEC Class 2 and 48 VDC @ 500 mA maximum. Figure 2-1 shows the alarm connection. Figure 2-1. Alarm Connection 28 Smart 16 Shelf User Manual 64202023L1-1 Fuses There are two fuses located on the rear panel. Fuse one (F1) corresponds to power supply 1 (left slot), and fuse two (F2) corresponds to power supply 2 (right slot). See Specifications and Features on page 63 for fuse ratings. AC/DC Power The single and dual AC versions, illustrated in Figure 2-2 on page 30 and in Figure 2-3 on page 31, each have captive 8-foot power cords. The power cords are terminated by a three-prong plug which connects to a grounded power receptacle. The grounded power receptacle should be installed near the shelf and be easily accessible. The power receptacle should also have suitable disconnect devices that are provided as part of the building wiring. The power receptacle should be properly grounded. The protection of the telecommunications network relies on the protective grounding of the Smart 16 Shelf. The single DC version, illustrated in Figure 2-4 on page 32, provides a 3-position screw terminal block for connection to a -48V source. The dual DC version, illustrated in Figure 2-5 on page 33, provides a 5-position screw terminal block for connection to both -48V sources. Pin 1 of the terminal block is frame ground. The 2nd generation dual input power interface cards are not compatible with the 1st generation Smart 16/16e shelves (4200023L3-L6). These dual power cards are 2nd generation only and are listed below: • Smart 16 Dual Input AC 1202035L2 • Smart 16 Dual Input DC 1202044L2 • Smart 16e Dual Input AC 1202163L2 • Smart 16e Dual Input DC 1202164L2 The 2nd generation single input power interface cards are fully compatible with the earlier 1st generation Smart 16/16e shelves. The single input power cards are listed below: • Smart 16 AC 1202035L1 • Smart 16 DC 1202044L1 • Smart 16e AC 1202163L1 • Smart 16e DC 1202164L1 64202023L1-1 Smart 16 Shelf User Manual 29 Figure 2-2.
