3.1.1.7 Power Supplies
Each module contains two removable power supplies. The power supplies provide
power to the internal components by converting incoming AC voltage to DC
voltage. If one of the power supplies is turned off or malfunctions, the other power
supply can maintain electrical power to the command module.
Figure3-7 shows the power supplies, which are interchangeable by reversing the
locking levers.

3.1.1.8 SFP Transceivers and Cables
Each module supports either copper (for drive extension only) or fibre optic
interface cables. If fibre optic cables are used, a small form-factor pluggable (SFP)
transceiver must be installed in each interface connector on the controller where a
fibre optic cable is to be installed.
Figure3-8 shows an SFP transceiver and a fibre optic cable. Note that the SFP
transceiver shown may look different from those shipped with your unit. The
differences will not affect transceiver performance.
