Chapter 5 Diagnostics

Power-On Self Test

A Power-On Self Test (POST) sequence takes place when the TE100-S55 is first turned on (cold boot). Software reset (warm boot) through the RS-232 port does not prevent unauthorized remote re-boots.

The POST sequence checks the system integrity by performing the following tests:

System boot

RAM test

Timer and interrupt controller tests

Cache controller test

RS-232 diagnostic port test

BIOS test

EEPROM checksum test

Program load checksum test

Ethernet ports test

Besides the Power On/Off LED, there are eight system Status LEDs used to display the results of these tests during the POST sequence. The LED status further display test results in two categories, the System test and the Port test. Any errors from the System tests means that the Switch failed to function. Any error(s) from the Port test effects that individual port and the remaining ports will be operational.
