Technical data

9.35 picofarads (pf). A dc load is the amount of dc leakage current a
module presents to a bus signal line. One dc load is approximately 105
microamperes (µA). The backplane presents 4.0 ac loads to the Q22-bus.
There are connectors provided for each of the following:
• Fan tray
• System control panel (SCP)
• Four mass storage compartments
• Power supply
• Vterm regulator module
