SX-200 EL/ML Peripheral Interface Card Slot
Assignments
With LIGHTWARE 17 and greater, the SX-200 EL/ML cabinets do not
have high power and low power designations. Slots 1 to 8 can accept
any peripheral interface card, except T1 trunk. A maximum of four
high-power cards are allowed (there are no high-power or low-power
slots). Beginning at slot 1, the system accepts the first four high power
cards it detects. The high-power cards are DID, Universal, COV, and
T1. T1 Trunk cards can be installed in slots 10 and 11 only, but they
require slots 5 and 6 respectively to be left empty. Software recognizes
slots 5 and 6 as being occupied and the T1 cards are counted as high
power cards in slots 5 and 6.
