2.....Avocent® Universal Management Gateway Appliance Installer/User Guide
Avocent® Universal Management Gateway 4000 and 6000 appliances have 40 autosensing ports
that can be used for service processor (SP)or serial connectivity and management.
Ports that support autosensing are designated on the back of the appliance with a small turquoise
line next to the port number. Ports indicate which mode of operation is currently active with a green
or amber connection LED. By default, all ports capable of autosensing are in automode. It is
recommended to leave the port set to autosense. This is indicated by having both the green and
amber LEDs illuminated. If a port is statically set to one of the two modes, the corresponding LED
will be the only one illuminated.
Autosensing Port
Network and serial mode
The autosensing ports can operate in network or serial mode. Each major mode has sub modes
called port classes. The network port class is for network or SP connections. The port will
autosense network targets but will need to be manually configured for SP connected targets. The
serial port class is for console connections or PDU connections. By default, the serial port class will
autosense to a console connection and will need to be manually configured for a Power Distribution
Unit (PDU) connection. The ports will autosense and switch to the appropriate mode depending on
the target attached to the appliance.
When a port is in network mode, the green LED will be illuminated. The appliance will provide an IP
address to the network device attached to it. It is only intended to be connected to the device to be
managed or accessed. The appliance will not function as a traditional network switch or common
network access firewall. It is a special purpose appliance intended for target device access and
management.
CAUTION: Since the appliance issues IP addresses using DHCP, they could conflict with a production
DHCP infrastructure. Proper VLAN segmentation must be assigned on the network to avoid this conflict.
