ERS II and
ERS/FT II
Chapter 6 - Component Installation
This chapter includes the following installation instructions:
1. Turn power off to the subsystem. Note that on an ERS/FT II, this requires turning off both of the power switches.
* In an ERS/FT II, it is possible to install a new processor without turning off power to the entire subsystem. This is accomplished by powering down the group of slots where the new processor is to be installed. Although the new processor will function properly, it will not be accessible via the front panel console nor will the IES recognize the new board until the subsystem is reset and reconfigured (refer to step 11 of these instructions).
2. Remove the cover:
3. If the BC processor is being installed into an EISA group, the processor board must be placed in the master controller slot which is longer than the other slots in the group. If the BC processor is being installed in an ISA group, it should be placed in the leftmost slot in the group (away from the power supply). Seat the BC board securely in the leftmost slot of the group (away from the power supply).
4. Secure the end bracket of the board with the screw provided.
5. The multiplexor contains three connectors for each of the eight possible groups in the subsystem: a 34-pin connector for the muxed floppy drive, a 26-pin connector for all other BC I/O, and a 16-pin connector for Multiport board support (refer to Figures 3 - 4 and 3 - 5). Using a 26-pin ribbon cable provided with the subsystem, connect J3 on the top of the BC processor to the leftmost 26-pin connector in this group on the multiplexor.
6. Using the 34-pin ribbon cable provided with the subsystem, connect J1 on the top of the BC board to the leftmost 34-pin connector in this group on the multiplexor.
7. If a hard disk drive is to be installed for this BC processor, follow the instructions in the Storage Device Installation section later in this chapter.
8. If connectors are required for this processor in the rear panel, follow the instructions in the Connector Installation section later in this chapter.
9. Replace the top cover and secure with the quarter turn fasteners.
10. Apply power to the subsystem. If only a group of slots in an ERS/FT II was powered down prior to installing the new processor, power on the group and skip step 11.
11. If this is an ERS/FT II subsystem, press the BC Group Up pushbutton during the five second countdown displayed on the console to force the subsystem to reconfigure and recognize the new BC processor.
1. Turn power off to the subsystem. Note that on an ERS/FT II, this requires turning off both of the power switches.
* In an ERS/FT II, it is possible to install a new processor without turning off power to the entire subsystem. This is accomplished by powering down the group of slots where the new processor is to be installed. Although the new processor will function properly, it will not be accessible via the front panel console until the subsystem is reset and reconfigured (refer to step 13 of these instructions).
2. Remove the cover:
3. The BC Supervisor should be installed in the last group in the subsystem (the group closest to the power supply). Note that on EISA backplanes, this group will allow installation of an ISA processor in the master EISA controller slot, which is longer than the other slots in the group. If the BC processor is being installed in an ISA group, it should be placed in the leftmost slot in the group (away from the power supply). Seat the BC Supervisor securely.
4. Secure the end bracket of the board with the screw provided.
5. The ERS/FT II subsystem contains three connectors for each of the eight possible groups in the subsystem: a 34-pin connector for the muxed floppy drive, a 26-pin connector for all other BC I/O, and a 16-pin connector for Multiport board support (refer to Figures 3 - 4 and 3 - 5). Using a 26-pin ribbon cable provided with the subsystem, connect J3 on the top of the BC processor to the leftmost 26-pin connector in this group on the multiplexor.
6. Using the 34-pin ribbon cable provided with the subsystem, connect J1 on the top of the BC board to the leftmost 34-pin connector in this group on the multiplexor.
7. If a new rear panel must be installed to support the RJ-11 connectors for the BC Supervisor, follow the instructions in the Rear Panel Installation section later in this chapter.
8. Connect the COM2 header on the BC Supervisor (J8) to the adapter board containing the two RJ-11 connectors on the rear panel.
9. If a hard disk drive is to be installed for the BC Supervisor, follow the instructions in the Storage Device Installation section later in this chapter.
10. If connectors are required for this processor in the rear panel, follow the instructions in the Connector Installation section later in this chapter.
11. Replace the top cover and secure with the quarter turn fasteners.
12. Apply power to the subsystem. If only a group of slots in an ERS/FT II was powered down prior to installing the new processor, power on the group and skip step 13.
13. If this is an ERS/FT II subsystem, press the BC Group Up pushbutton during the five second countdown displayed on the console to force the subsystem to reconfigure and recognize the new BC Supervisor.
1. Turn power off to the group that will contain the new QL board (in an ERS II subsystem, this requires powering down the subsystem).
2. On an ERS/FT II subsystem, if a Cubix data highway is connected via the IES IN connector on the rear I/O panel of the subsystem, disconnect the data highway cable. This is to prevent BCVision from turning a powered down group back on during this installation procedure.
3. Remove the cover:
4. Seat the BC board securely in any available slot in the group.
5. Secure the end bracket of the board with the screw provided.
6. The ERS/FT II contains a ninth custom channel. This channel can be used to connect a QL processor to the muxed devices for installation purposes. If the custom channel is to be used for this processor, verify that a Custom Channel Cable Kit is available. These kits may be acquired from Cubix Corporation. Each kit includes:
* If a QL 4001 requires connection to the muxed devices via the custom channel, a QL 4001 Custom Channel Cable Kit may be ordered. This kit includes the 14-pin cable required by the QL 4001. Use this 14-pin cable and the 14-pin connector on the custom channel in place of the 26-pin references below.
Connect the 26-pin header from the top of the QL processor to the 26-pin header on the custom channel (refer to Figure 3-5). If the QL processor supports a floppy drive, use a 34-pin ribbon cable provided with the subsystem to connect the floppy header from the top of the QL board to the 34-pin connector in the custom group on the multiplexor.
* Verify that the custom channel is enabled on the Multiplexor Option Switch.
7. If a hard disk drive is to be installed for this QL processor, follow the instructions in the Storage Device Installation section later in this chapter.
8. If connectors are required for this processor in the rear panel, follow the instructions in the Connector Installation section later in this chapter.
9. Replace the top cover and secure with the quarter turn fasteners.
10. If the Cubix data highway was disconnected, connect it back to the subsystem.
11. Apply power.
1. Turn power off to the subsystem. Note that on an ERS/FT II, this requires turning off both of the power switches.
* In an ERS/FT II, it is possible to install a new multiport board without turning off power to the entire subsystem. This is accomplished by powering down the group of slots where the new board is to be installed. Although the new board will function properly, it will not be accessible via the front panel console until the subsystem is reset and reconfigured (refer to step 9 of these instructions).
2. Remove the cover:
3. Seat the Multiport (MP) board securely in any available slot in the group.
4. Secure the end bracket of the board with the screw provided.
5. If this is the only MP board in this group, it must be connected to the multiplexor. The multiplexor contains three connectors for each of the eight possible groups in the subsystem: a 34-pin connector for the muxed floppy drive, a 26-pin connector for all other BC I/O, and a 16-pin connector for Multiport board support (refer to Figures 3 - 4 and 3 - 5). Using a 16-pin ribbon cable, connect the 16-pin header on the top of the MP board to the leftmost 16-pin connector in this group on the multiplexor.
6. If this is not the only MP board in this group, the board must be connected as follows. Each cable attaching an MP board to the multiplexor is capable of connecting two MP boards to a single mux connection. This is accomplished using a cable provided by Cubix which provides three connectors: one end of the cable connects to the mux, the middle connector attaches to the header of the first MP board, and the other end of the cable connects to the header of the second MP board.
- If there is an MP already installed that has an unused connector on its mux cable, connect the new MP board to this unused connector.
- If there are already two MP boards on each MP mux connection being used in this group, connect the new MP board to an unused mux connection also in this group. Since there is one mux connection per two slots, there will be a connection available.
7. Replace the top cover and secure with the quarter turn fasteners.
8. Apply power to the subsystem. If only a group of slots in an ERS/FT II was powered down prior to installing the new multiport board, power on the group and skip step 9.
9. If this is an ERS/FT II subsystem, press the BC Group Up pushbutton during the five second countdown displayed on the console to force the subsystem to reconfigure and recognize the new MP board.
There are five types of drive installations included in this section:
3.5" Disk Drive Installation

2. Using the mounting screws, attach the drive mounting bracket to the drive with the bracket lip extended over the drive.
3. Turn power off to the group that contains the processor that the drive is to service (in an ERS II subsystem, this requires powering down the subsystem).
4. On an ERS/FT II subsystem, if a Cubix data highway is connected via the IES IN connector on the rear I/O panel of the subsystem, disconnect the data highway cable. This is to prevent BCVision from turning a powered down group back on during this installation procedure.
5. Remove the cover:
6. Lift the fan panel.
