Proceed as follows:
Take the SFP transceiver out of the transport packaging (1).
Remove the protection cap from the SFP transceiver (2).
Push the SFP transceiver with the lock closed into the slot until it latches
in (3).
2.3 Wiring of the terminal blocks for supply
voltage and signal contact
The supply voltage is electrically isolated from the casing.
The voltage supply is connected via a 3-pin terminal block with screw locking.
The signal contact is connected via a 2-pin terminal block with screw locking
(1 × or 2 ×, depending on device variant).
For device variants without PoE: The supply voltage in MACH1040/
MACH1140 device variants can be connected redundantly with 2 power
supply units. Both inputs are uncoupled.
MACH1040 device variants without PoE
MACH1040 device variants without Power over Ethernet (PoE) are,
depending on the device variant, equipped with 1 or 2 power supply units
of the following characteristic value.
Power supply characteristic value L
Power supply characteristic value M
See “General technical data” on page 45.
For devices without PoE featuring 2 power supply units, you can connect
the supply voltage redundantly. Both inputs are uncoupled. With a non-
redundant supply of the supply voltage, the device reports the loss of a
supply voltage. You can prevent this message by applying the supply
voltage via both inputs, or by changing the configuration in the
Management.
MACH1040 devices with PoE
MACH1040 device variants with Power over Ethernet (PoE) are equipped
with 2 power supply units.
Power supply unit 1 is freely selectable from the combination table.
Power supply unit 2 is a PoE power supply unit.
See “Combination options” on page 18.
