C578M-A (4/05) 5 Prior to installation and use of this product, the following W ARNINGS should be obser v ed. 1. Installation and servicing should only be done by qualified service personnel and conform to all local codes.

C578M-A (4/05) 7 Figure 1-2. CC1 Connection Groups 1.2 CC1 CONNECTION GROUPS The rear view of a matrix switch (referenced in the block diagram of Figure 1-1) is shown in Figure 1-2. Outputs destined for HS connections can be categorized, corresponding to the designated functions of the subunits to which they are attached on the hot switch.
8 C578M-A (4/05) 1.4 SUBUNIT HIGHLIGHTS The main characteristics and functions of each subunit of the HS are discussed in the following paragraphs. Important points that need to be understood for a successful installation are discussed.
C578M-A (4/05) 9 LOGGING PRNTR A B A B OUT IN 120-240 VAC 50/60 Hz C C 1 20053 THE CCC (Computer Changeover Control) The CCC subunit is the heart of the hot switch. Data connections between the interfaced CC1s (matrix switches) and the HS are located here.
10 C578M-A (4/05) In addition to communications, there are number of additional functions handled by the CM9760-CCC. POWER The power-input connector , fuse, and ON/OFF s witch are located here. Input power for the entire HS originates here. Power is distributed to the CPS and SEU subunits via DB37 common bus connections.
C578M-A (4/05) 11 This allows users with existing RS-232 DT devices to retain that configuration capability in the new HS. Figure 1-6 highlights the geometry of this hookup. Additional DTs of the same type must be connected to CC1 Sercom por ts (via SEU output ports of the HS) and require RS-232 to -422 converters.
12 C578M-A (4/05) THE SEU (Serial Expansion Unit) The SEU subunit of the HS, like that of the CPS, is also divided into three sections. Devices connected to the SEU EQUIPMENT output por ts are under the control of only one CC1 at a time. The controlling switch is designated the Master , regardless of mode (synchronous or asynchronous).
C578M-A (4/05) 13 MASTER/SLA VE ST A TUS FOR CC1 Sercom port 1 on the CC1-A or CC1-B side of the SEU subunit may be wired to provide the current status of the CM9760-HS. This wiring connection will allow f or monitor ing that alerts the user to primary (master) CPU (CC1) failure.
14 C578M-A (4/05) 1.5 INST ALLA TION PREVIEW Figure 1-11 combines elements of previous illustr ations into what is essentially a wire routing of the bloc k diagram of Figure 1-1. This is an overvie w of the ph ysical geometr y of an HS integrated into a basic, default system configuration.

16 C578M-A (4/05) SECTION 2.0: INST ALLA TION 2.1 PHYSICAL As previously stated, the connections from 9700-CC1s (CC1-A and -B) to the HS are duplicates of each other . Except where noted, all the plugs and connectors found on the rear of the CC1 ha ve corresponding port representations on the subunits of the HS.
C578M-A (4/05) 17 9700-CC1 TO CPS (Diagnostic Group) The connection points for diagnostic and monitor tools for hot switch and system status are shown in Figure 2-2. Note that COM 1 on either CC1 (the normal connection point for the PC w/MGR in a stand-alone CC1 configuration) is run to the appropriate COM 1 input connector on the CPS.
18 C578M-A (4/05) 9700-CC1 TO SEU (Expansion Group) Devices connected to the EQUIPMENT output port (which the designated Master switch has access to) are implemented here. Port destinations for cable connection inputs from the matrix switches are not predefined.
C578M-A (4/05) 19 DIP SWITCH SETTINGS Some HS operating parameters are determined via two DIP switches, which are physically located to the left of the front panel LED displays, but behind the front panel of the CCC itself. Figure 2-4 illus- trates all DIP switch settings.
20 C578M-A (4/05) 2.2 POWER-UP AND INITIALIZA TION Once configuration files have been programmed and loaded and all connection cabling has been run, then the associated CC1s, the hot switch and all connected devices can be turned on.
C578M-A (4/05) 21 SECTION 3.0: OPERA TION 3.1 PRELIMINAR Y REMARKS There are two modes of HS operation. One is termed the synchronous mode and the other , the asyn- chronous mode. Synchronous mode, of course, is the desired mode of operation. It is the optimal mode of operation and the one the HS is designed to operate under .
22 C578M-A (4/05) 3.3 OPERA TOR TOOLS LEDs A visual check of LED activity should be the top item on your checklist for determining the operational status of the HS and the attached system.

24 C578M-A (4/05) The following table illustrates how to implement these actions for the HS. Included are pertinent “before and after” visual changes associated with the action along with applicable notes about system operation.
C578M-A (4/05) 25 3.4 OPERA TOR RESPONSES AND METHODS User interaction with the HS is necessary when (1) a system error occurs, which generates a F A UL T LED, and (2) when a software/hardware change or upgrade to the system must be made. System F A UL TS are discussed first.
26 C578M-A (4/05) DIAGNOSTIC MONITOR AND SYSTEM WINDOW USE Normal Operation During normal startup, the diagnostic screen on the monitor (attached to the VGA output of the CPS- see Figure 1-11) reflects successful hot switch initialization.

C578M-A (4/05) 31 SECTION 4.0: APPENDICES INTRODUCTOR Y REMARKS All appendices (except Appendix 4.5 ), focus on specific installation issues or v arious situations of interest to the user . Each deals with a separate aspect of integrating the current HS into the described system environment.
32 C578M-A (4/05) APPENDIX 4.2 HS UPDA TE (Previous Model of Hot Switch Installed) The previous model of the hot s witch has e xisted for some time. Those acquainted with its opera- tional characteristics know the uses and characteristics of a hot switch.
C578M-A (4/05) 33 Figure A4-1 also highlight the two major diff erences between the current and previous hot s witch: 1. COM Port Flexibility The COM 1 and COM 2 Destination ports for the previous hot switch allowed for the connection of the PC w/MGR and, if desired, an ASCII Control De vice interfaced via a P elco DT , for example .

C578M-A (4/05) 35 Interfacing network nodes with a hot s witch (illustrated in Figure A4-2) can be extended to include the NIU itself. Figure A4-3 k eeps the same node structure shown in Figure A4-2, except that no w a hot switch interfaces the NIU.
36 C578M-A (4/05) APPENDIX 4.5 DA T A CABLE P ARAMETERS Data communication cables are used in the CM9760 system to connect required equipment to appropriate data communication ports on the CC1, which are RS-232 or RS-422 driven. The characteristics of the cable chosen (if not supplied) depends, first of all, on the driver type it interfaces.
C578M-A (4/05) 37 Remote Hookup of the CM9760-KBD The 9760 keyboard comes with associated cables and a CM9505UPS (universal power supply) to supply the 12V needed to power the k eyboard. The standard hookup for the k eyboard to the matrix s witch (CC1) is shown in Figure A4-5.
38 C578M-A (4/05) For remote installation of the keyboard, the user must supply a cable of appropriate length that supports the TIA/EIA-422-B (RS-422) communication standard. The example in Figure A4-6 shows a k eyboard placed 2,000 feet (610 m) from the CC1 via the user-supplied cable.
C578M-A (4/05) 39 In either case, P elco recommends using a cable similar to Belden 9843, that meets or e xceeds the suppor t requirements for TIA/EIA-422 ap- plications. T ableA4-A is tak en directly from the FULL TECHNICAL SPECS page in Belden’ s Cab le Catalog located on their company web site.
