Hardware Diagnostics

The power and status LEDs indicate the general operations of the HiSpeed switch. The HiSpeed switch provides transparent operation once it has been installed and configured. If you suspect that it may be malfunctioning or causing a system problem, check the status of the LEDs. Call Technical Support to report the condition.

In addition to the built-in LEDs on the switch, there is an Integrated System Diagnostic (ISD) software which tests the system to determine any hardware failures. The system diagnostic’s focus is to help identify and verify major system features and components such as the processor, memory, I/O devices, system buses, packet switch and uplink interfaces on the switch.

The ISD software (isd) and download instructions (isd.doc) are available on the Hitachi anonymous FTP server, 204.48.18.63. If you are using a browser, type in the following URLs to download the files:
