In auto-negotiation mode, H0FL-EthMux.SA16/SAP16 series device Ethernet
electrical port supports HP auto-MDIX function, which can automatically detect
the transceiver line order of the network cable connected and make adaptions. So
the port can be used whether the Ethernet port is MDI or MDI-X and whether the
network cable used is crossover or straight-through.
3.1.6 Power Switch and Power Socket
H0FL-EthMux.SA16/SAP16 series device supports -48V DC and ~220V
AC power supplies. The ~220V AC power supply uses ~220V AC power
socket which complies with national standard and is connected by standard
three-core power cable. The -48V DC power is connected by 2x2 socket.
When connecting AC power cable, IEC standard power cable sent with
device will be used. The middle electrode of AC power socket is protection
ground electrode. When connecting DC power cable, DC power cable sent
with device will be used. Note that the red wire of power cable is high
potential, i.e. power ground of -48V power supply, and that the blue wire is
low potential, i.e. -48V. When inserting the power plug, please note the
direction of the locking lever. The yellow-green wire of DC power cable
sent with device is ground line. Make sure that the device has connected to
the ground when installing it.
For user’s safety, when ~220V AC power supply is used, the AC power
socket must have good protection ground connection! When DC power
supply is used, the DC power socket must have good protection ground
connection!
