Description: This field specifies the diagnostic to execute. The default 
value is 'selftest'.

NOTE: not all of the individual diagnostics are available on 
      every Zhone card type.
NOTE: Zhone card types (cardZhoneType) are defined in the
      genCardResources.mib

List of possible diagnostics:
============================
Common to all PLS cards
-----------------------
selftest(1) 
  - this diagnostic will execute all of the individual tests 
    available on this card.
    Supports: diagStart, diagStop, diagRepetition.
cardEEprom(3) 
  - this diagnostic will verify the main card EEPROM checksum.
    Supports: diagStart, diagStop, diagRepetition.
frbus(4) 
  - this diagnostic will verify that the BAN slot card can 
    access the Fhrame Bus by doing a loopback with 10 message
    of 100 bytes.
    Supports: diagStart, diagStop, diagRepetition.
backPlane(12)
  - this diagnostic will verify that the BAN slot card can
    access the back plane by verifying the back plane EEPROM
    checksum.
    Supports: diagStart, diagStop, diagRepetition.

cardZhoneType::infoServices(3) specific
---------------------------------------
supvBus(2)
  - this diagnostic will verify that the BAN slot card can
    access the supervisory Bus by doing a loopback of 20 
    bytes.
    Supports: diagStart, diagStop, diagRepetition.
pcmcia(5) 
  - this diagnostic will verify that the InfoServ card can
    access the PCMCIA flash card I/O by doing a file create,
    write, and read of length 4000 bytes.
    Supports: diagStart, diagStop, diagRepetition.
shelfLamp(6)
  - this diagnostic will illuminate the shelf alarm indicators 
    for a period of 1.5 seconds. The indicators will return to
    their original settings after the diagnostic completes.
    Supports: diagStart, diagStop, diagRepetition.
realTimeClk(7) 
  - this diagnostic will verify that the real time clock 
    increments.
    Supports: diagStart, diagStop, diagRepetition.
fanTray(8) 
  - this diagnostic tests that the fan tray is operational by 
    verifying the fan tray EEPROM checksum.
    Supports: diagStart, diagStop, diagRepetition.
shelfMonitor(9) 
  - this diagnostic tests the shelf monitor board is operational 
    by checking the POST status register and verifying the shelf 
    monitor board EEPROM checksum.
    Supports: diagStart, diagStop, diagRepetition.
midPlane(13) 
  - this diagnostic will verify that the mid plane card is present 
    by verifying the mid plane card EEPROM checksum.
    Supports: diagStart, diagStop, diagRepetition.

cardZhoneType::vasp(5) specific
---------------------------------
ioCard(10) 
  - this diagnostic will verify that the I/O card is present by 
    verifying the I/O card EEPROM checksum.
    Supports: diagStart, diagStop, diagRepetition.
mezzanineCard(11) 
  - this diagnostic will test that the mezzanine card is operational
    by verifying the mezzanine card EEPROM checksum.
    Supports: diagStart, diagStop, diagRepetition.

cardZhoneType::t3Tdm(6) specific
---------------------------------
ioCard(10) 
  - this diagnostic will verify that the I/O card is present by 
    verifying the I/O card EEPROM checksum.
    Supports: diagStart, diagStop, diagRepetition.
midPlane(13) 
  - this diagnostic will verify that the mid plane card is present 
    by verifying the mid plane card EEPROM checksum.
    Supports: diagStart, diagStop, diagRepetition.

cardZhoneType::ethernet(9) specific
-----------------------------------
midPlane(13) 
  - this diagnostic will verify that the mid plane card is present 
    by verifying the mid plane card EEPROM checksum.
    Supports: diagStart, diagStop, diagRepetition.

cardZhoneType::hdsl2(10) specific
---------------------------------
ioCard(10) 
  - this diagnostic will verify that the I/O card is present by 
    verifying the I/O card EEPROM checksum.
    Supports: diagStart, diagStop, diagRepetition.
mezzanineCard(11) 
  - this diagnostic will test that the mezzanine card is operational
    by verifying the mezzanine card EEPROM checksum.
    Supports: diagStart, diagStop, diagRepetition.
