Epica DGX 32 Board(s)
Phillips #1 screwdriver
ESD wristband and cord with alligator clip

Be sure to apply the power last, so that the fiber connector is not exposed when power is
applied.
Do not remove dust plugs from SC fiber connectors or the dust caps from the fiber cables until
establishing connections; avoid direct eye exposure.
Ensure all cables, including fiber cables, are correctly connected and/or terminated.
If you need to unplug a fiber cable on an input board, disconnect the power on the DGX TX
that is connected to the input.
If you need to unplug a fiber cable on an output board, disconnect the switch for that output
connector.
