ERS II and
ERS/FT II
Chapter 7 - Troubleshooting
| Problem | Resolution |
| Mux indicates a shunt connector, but none is installed. | Hard drive power connector is in the wrong group. Plug into the same group as the BC processor. |
| Mux front panel lights behave erratically. | The 26-pin BC to mux cable is installed incorrectly. Ensure pin 1 connectors are aligned. |
| The BC group displays as "E". | Refer to chapter 5 for a list of error codes. |
| The muxed video, mouse, and keyboard will not function. | The 26-pin BC to mux cable is installed incorrectly. Ensure pin 1 connectors are aligned. |
| Subsystem status lights are amber, "Subsystem Fault" light alternates flashing amber and green. | Factory test switches are on and the mux is in debug mode. Power down and reset the switches on the front of the multiplexor panel. |
| The mouse appears to pause when a new group is selected and Windows is running. | The mouse is reset every time the group is changed. This takes a couple of seconds. Give the mouse time to reset before proceeding. |
| The mouse misbehaves in the Windows environment. | Verify that the VHOTFIX.386 device driver is installed in the SYSTEM.INI file. This driver is shipped with the BC processors. |
| BCVision cannot communicate with the ERS/FT II. | If a fatal error has occurred, communications with BCVision will be lost. See Table 5 - 1 for a list of fatal conditions. |
| Floppy files have been corrupted. | The floppy drive must not be active when enabling/disabling the subsystem or when activating/deactivating the keylock. |
| The ERS/FT II disables itself when it should be enabled. | The keyboard circuit breaker on the mux board is suspect. |
| The console display is garbled and nonfunctional. | Old IES firmware was downloaded to the ERS/FT II. Cycle power to the subsystem and download the correct firmware via BCVision. |
| No video appears when selecting a particular group. | The BC in the group may not have been found during automatic configuration. Cycle power on the subsystem and force it to reconfigure by pressing the BC Group Up push-button during the 5 second countdown. |
| A stuck switch Power On Self Test error is displayed. | This error can occur if the BC Group Up push-button is pressed to force an automatic configuration before the 5 second countdown begins. |
| The "LAN Attached" LED is on when a QL is attached to the custom channel. | This LED will be illuminated when the QL is in reset. |
This issue applies only to ERS/FT II subsystems running IES Supervisory Software v1.33 or higher. The information contained here explains how to recover if a BC Supervisor residing in an ERS/FT II is placed offline. The BC Supervisor is the BC processor running BCVision.
Because BCVision is installed on a BC processor, it can be used to manage itself (i.e., the BC Supervisor). If BCVision is instructed to take the BC Supervisor offline, the processor running BCVision is placed offline and the BCVision application will no longer function. Therefore, the user cannot use BCVision to place the BC Supervisor back online.
To restore the BC Supervisor to an online state, follow the steps below.
1. Verify that none of the BC processors in the ERS/FT II are in use.
2. Turn power off to the ERS/FT II. Note that this requires turning off both power switches.
3. Remove the cover from the ERS/FT II.
4. Lift the fan panel.
5. Locate the 8-position DIP switch labeled IES ADDRESS. Turn switch number 8 OFF (down).
6. Close the fan panel and apply power to the ERS/FT II.
7. In this mode of operation, the BC Supervisor will come online, but the IES Supervisory System will not be fully functional. From the BC Supervisor, run BCVision and instruct it to place the BC Supervisor online.
Note: Even though the BC Supervisor is currently online and running BCVision, this step is necessary to keep the BC Supervisor from being placed offline when the IES functions are enabled.
8. Exit from BCVision.
9. Turn power off to the ERS/FT II.
10. Lift the fan panel.
11. Turn switch number 8 of the IES ADDRESS DIP switch ON (up). Note: This switch must be turned on for the IES Supervisory System to function properly.
12. Close the fan panel.
13. Replace the cover.
14. Apply power to the ERS/FT II. The BC Supervisor and the IES Supervisory System should function properly.
* BCVision allows the user to assign an alias, or text description, to each BC processor. It is recommended that the alias be used to specify which BC is the BC Supervisor. This may prevent a user from inadvertently placing the BC Supervisor offline.
