The buttons and LEDs serve two functions. The green button resets/restarts the
controller. The six recessed buttons allow the port (associated with each button)
to be quiesced when the button is pushed, allowing for a device warm swap, thus
decreasing subsystem down time. Use a pointed object to push any of the six
recessed port buttons.
Note
The HSZ40–Bx OCP maintenance terminal port connector is center-keyed.
A short phone cable and coupler come with each controller to convert
from a center-keyed to offset-keyed configuration as appropriate for your
system. Look for the ‘‘HSZ40B’’ on the front bezel label.
2.1.8 Program Card (PCMCIA)
The program card is a PCMCIA standard program card device. After a set of
minimum integrity diagnostics are complete, the controller firmware is copied
from the program card to the first 2 MBs of shared memory in the controller
using error correction code (ECC) to correct program card errors when possible.
This occurs each time the controller initializes.
