Note:
1.
At auto-negotiation mode, Ethernet electrical port supports HP auto-MDIX
function and it can check the transmission and receiving sequence and make
configuration. So both MDI and MDI-X interfaces are supported and both
cross line and direct line can be selected.
2.
Network Management can be used for all the Ethernet ports except Data1
port. But to ensure VLAN setting will not impact the normal
monitoring,
it’s better to use the Ethernet electrical port labeled “Data2/NM” as the
network management monitoring interface.

Power Switch and Power Socket
Two power options are available, ~220V AC or -48V DC. It should be
specified at the time of purchase.
