BC 5200TX Series
Chapter 3 - Installation

1. Configure the hardware options as described in Chapter 2.
2. Power down the System or the group in which the board will be installed.
3. Gain access to the backplane by removing the cover from the System.
4. Seat the board into the appropriate group in the backplane and secure the board with the screw on the end bracket.
5. Install any additional peripheral devices required in the group.
6. Install any adapters required to provide connectors for peripheral devices such as LPT or COM2, as described later in this chapter.
7. Connect the cables to all peripherals and I/0.
8. Reassemble the system as necessary.
9. Apply power.
10. Use a monitor and keyboard to verify that the system is functioning properly. Monitor, keyboard and mouse support are provided through the Cubix System.
11. Configure the CMOS as needed. To enter the BIOS Setup Utility, hit the DEL key during boot.

The board is equipped with an integrated fast/wide SCSI adapter. This adapter is enabled or disabled via the Chipset option of the BIOS Setup utility and via hardware with jumper JP6. The SCSI adapter is a bus master device which gains control of the PCI bus to transfer data between the CPU memory and the SCSI devices. The I/0 base address and interrupts are set by the PCI plug and play BIOS at boot time.

On-board SCSI termination is controlled by dip switches 4 and 5 of switch S2. Normally, both switches are off, which terminates the high and low order bits of the SCSI bus.

Note: Termination should also be configured as "enabled" if the SCSI interface is not used. The last device on the SCSI cable must also supply a termination load to the cable. SCSI devices not at the end of the cable must have their termination loads disconnected. Enabling and disabling a SCSI device's termination may involve a switch or shunt setting or the installation or removal of resistive SIP or DIP packages on their circuit board. Consult the installation manual for the SCSI device to determine its termination options.

The BC 5200TX boards support PCI bus extension via the connection of an optional PCI bus extender card. The extender card, which connects to the 80-pin connector at location J16 on the BC board, extends the PCI bus to an ERS/FT II PCI Master Interconnect Board (MIB). When installed in the ERS/FT II subsystem, the ISA connectors on the BC board and the PCI connectors on the PCI bus extender card simultaneously engage the ISA and PCI connectors on the MIB. The only subsystem that supports PCI extensions is the ERS/FT II.

The passive extender card (figure 3-5) is used on PCI MIBs with one or two PCI expansion slots.

PCI Bus Extender Card Installation

The PCI bus extender card is shipped with four #6 screws and two spacers. These parts are used to secure the extender card to the BC processor.

Optional Cubix peripheral adapter boards are available for VKM (Video/Keyboard/Mouse), LPT1, and COM 2. To install the adapters, follow the steps listed below.

1. Install the Cubix adapter in a panel opening on the system. Typically, an opening provided for an empty board space is dedicated to the adapter. In this case, install the bracket next to the board that requires the adapter port and tighten the screw firmly. Alternately, if the adapter is being installed into a Cubix auxiliary junction panel, the bracket provided with the adapter should be removed. Unscrew the connector from the bracket and install the adapter into the desired panel opening.
2. Connect one end of the provided cable to the appropriate header on the processor board. The pin-one side of the ribbon cable is marked with a colored (blue or red) stripe. Pin one on the header is labeled with a triangular arrowhead. Align the pin-one side of the ribbon cable with pin one on the header.
3. Connect the other end of the ribbon cable to the adapter. Pin one on the adapter's box header is labeled with a triangular arrowhead. Align the pin-one side of the ribbon cable with pin one on the adapter.
4. Plug the peripheral device's cable into the connector.

The board is equipped with an integral DEC 21140 PCI fast Ethernet controller with a RJ-45 10/100 BASE-T connector on the mounting bracket at the rear of the board. This adapter is enabled or disabled via the "Chipset" option of the BIOS Setup utility and via hardware with jumper JP6. The I/O addresses and interrupts are set by the PCI plug and play BIOS at boot time. Software drivers are provided for this controller to support PC local area networks.

Near the RJ-45 connector and visible in the mounting bracket are two sets of light emitting diodes (LED). On the lower set, the green LED will light when the interface has a valid connection to an Ethernet hub. The amber LED will light when the interface is set to 100 Mbit/s. On the upper set, the green LED indicates network activity, and the amber LED indicates a data collision on the network. These LEDs can be useful indicators of network activity.

The Line Busy RJ-11 jack is designed to be connected to the phone line that attaches to a modem. Its purpose is the make the telephone line appear busy when the processor or modem is not ready to answer an incoming telephone call.

The Line Busy circuit is designed to be used on rotary PBX systems to keep incoming calls from ringing on lines that will not answer. The circuit uses Data Terminal Ready (DTR) from the Cubix processor's communication port to determine whether the processor is ready for a call. If DTR is false, the circuit creates an off-hook condition on the telephone line to force the rotary PBX to bypass this extension for an incoming call. When DTR is true, the Line Busy Circuit will terminate the off-hook condition, and the processor will respond to an incoming call. The Line Busy circuit on the SP is controlled by the COM1 DTR signal. The COM2 port has no effect on Line Busy. Cubix processors assert DTR false on the reset operation. It is the responsibility of the communications application running in the processor to assert the DTR signal true.

The line busy circuit integrated onto the BC (J12) has been registered with the Federal Communications Commission for use on PBX's in the United States only. Use of this function outside the United States may violate local regulations and is not recommended by Cubix Corporation.

1. Connect the PBX modular telephone cable to the "Line" input of the modem.
2. Connect the modular telephone cable from the modem's "Phone" jack to the RJ-11 jack (J7), Figure 3-7.
3. If the modem phone jack is unavailable, a "T" modular jack can be used, as in Figure 3-8.
