2.10 Connecting External Devices
Warning: The 8580/8590 must be disconnected from the power supply:
- before external devices (e.g., scanner, keyboard) can be connected
or disconnected, and
- before the 8580/8590 can be connected to a network.
All connections and interfaces on the 8580/8590 are located on the
underside of the unit.
Important: Before connecting or disconnecting peripheral devices (excep-
tion: USB devices), the 8580/8590 must be disconnected from the
power supply! If the 8580/8590 is equipped with an optional UPS
battery, only open the device after the power LED has gone out.
Otherwise, this could seriously damage both the 8580/8590 and
the connected devices!
Make sure that external peripheral devices with their own power
supply are switched on at the same time as the 8580/8590 or after
you start the 8580/8590. If this is not possible, please ensure that
the 8580/8590 is adequately protected from power leakage caused
by an external device.
