Except for Maximum Allocation, the PoE settings are not user-editable. The Maximum
PoE Allocation allows you to set an upper limit to the power available to a connected
device, such as a node. Use Maximum Allocation to ensure critical devices will have
power. Also use Maximum Allocation to compensate for Class 0 device power
allocation. Many older PoE devices cannot report their class. The switch automatically
treats these devices as Class 0 and allocates the full, default 15.4W to their ports.
If Maximum Allocation for every port is left at 15.4W, PoE is allocated by the switch: a)
when the switch is powered up, PoE is allocated starting with Port 1, then port-by-port
through port 12; or b) PoE is allocated on a first-come, first-serve basis, dependent on
the order devices are plugged into the switch.
Troubleshooting tip: If the green PoE LED on the front panel is blinking, the maximum
allocation is too low for the connected device, the PoE power supply has not been set up
(see note below) or all available power is already allocated.
IMPORTANT NOTE: Models 6740, 6741 and 6742 ship with hardware support for IEEE
802.3af Power-over-Ethernet standard (PoE). In order to make use of this hardware, an
external 48VDC auxiliary power supply, such as Pathway # 700-7948-100, must be
connected to the VIA12.
Once the power supply is connected, the VIA must be configured with the size –
in watts – of the PoE supply USING PATHWAY’S SOFTWARE CONFIGURATION
TOOLS. The front panel does not allow a power supply size to be set at this time.
LLDP Link Partner
Link Layer Discovery Protocol (LLDP) is an industry-standard method for device
announcement and reporting described in the IEEE 802.1AB standard. Any Ethernet-
aware device may announce itself using LLDP, not just switches. Currently, the latest
Pathport and VIA firmware enables this protocol. The information shown in the chart
may be retrieved and shown on the VIA12’s LCD, for each Pathport LLDP-enabled
device connected to the switch, on a port-by-port basis. Other LLDP-enabled devices
may return different information. This property is only shown when a device is connected
to the port in question.
