Kernel halt error messages
Message | Description |
BAD Address = nn | Kernel memory is corrupt, hardware failure. |
|
|
Resetting to factory | A memory error is detected during a read from configuration memory. This also |
defaults | indicates a hardware failure, but the system may continue to initialize successfully. |
| The configuration from another Unit should be saved to this Unit as soon as |
| possible. |
|
|
Unit Halted | A major error has forced the kernel to stop processing. The UltraMatrix waits to |
| receive a kernel or main firmware file from the failed board’s serial port using the |
| serial parameters: 9600, N, 8, 1. Connect the serial cable supplied with the |
| UltraMatrix as described in the Serial Port section, start a terminal emulator and |
| transfer the file using an ASCII file transfer protocol. |

Appendix I. Rack mount
The optional rack mount kit includes the following items:
Two black anodized mounting brackets.
Four 6 - 32 x 3/8” flat head mounting screws.
To rack mount your Ultramatrix switch, attach the two rack mounting brackets to your Unit with the short flange against the Unit using the four screws provided. Secure the mounting brackets to the rack using the appropriate size bolts, nuts and lock washers. Using hardware other than that provided could cause damage to the electronics and/or result in loss of mounting integrity. Do not over tighten the screws used to mount the Unit to the mounting brackets.
The following general guidelines should be observed when installing your Unit into a rack.
a). The UltraMatrix is designed to work in an ambient temperature of 0ο C to 45ο C (32ο F – 113ο F). b). Do not block power supply vents or otherwise restrict airflow when
c). Mechanical loading of the rack should be considered to prevent instability and possible tipping over. d). Tighten all connectors securely and provide adequate strain relief for all cables.
e). Provide a grounded power source to all Units. Pay special attention to overall branch circuit load ratings before connecting equipment to this source. Overloaded circuits are potential fire hazards and can cause equipment failures or poor performance.
