Hardware diagnostic tools
System hardware diagnostic tools consist of:
• card self-tests
• LED indicators, and
• enable/disable switches.
Card self-tests
Mini-Carrier Remote cards automatically perform a self-test
• when inserted into an operating system module,
• when enabled, and
• upon system power up or reset.
A self-test may also be performed using software commands.
The self-test checks general card functions and determines if the card is operating correctly.
It is useful when first installing the cards because it gives an immediate indication of the card's
operating status.
LED indicators
MCR cards are equipped with red LED indicators and module power supplies are equipped
with green LED indicators. These indicators show the status of each card or power supply.
Mini-Carrier Remote LED indicators
Both the Local Mini-carrier Interface card and the Remote Mini-carrier Interface card have LED
indicators on the front panel. These are:
• Card LED—red LED indicating card status. If the LED is ON, the card may be faulty or
disabled. At power-up, the card LED blinks three times during self-test if functioning
