System Power Status
System Power Status shows a graph of
Sum of measured power
,
Sum of allocated power
, and
Max of
allocated power
. “Sum of measured power” (in green) shows the total measured power of all PDs, “Sum of
allocated power” (in blue) shows the total allocated power, and “Max of allocated power” (in red) shows the
threshold of total PoE power output. The graphs show
Current (mA)
versus
Sec. (second)
, and are refreshed
at the configured Refresh Rate.

VLAN
Setting up Virtual LANs (VLANs) on your Moxa switch increases the efficiency of your network by dividing the
LAN into logical segments, as opposed to physical segments. In general, VLANs are easier to manage.
The Virtual LAN (VLAN) Concept
What is a VLAN?
A VLAN is a group of devices that can be located anywhere on a network, but which communicate as if they are
on the same physical segment. With VLANs, you can segment your network without being restricted by physical
connections—a limitation of traditional network design. With VLANs you can segment your network into:
•
Departmental groups
—You could have one VLAN for the marketing department, another for the finance
department, and another for the product development department.
•
Hierarchical groups
—You could have one VLAN for directors, another for managers, and another for
general staff.
•
Usage groups
—You could have one VLAN for email users and another for multimedia users.
Benefits of VLANs
The main benefit of VLANs is that they provide a network segmentation system that is far more flexible than
traditional networks. Using VLANs also provides you with three other benefits:
•
VLANs ease the relocation of devices on networks:
With traditional networks, network administrators
spend much of their time dealing with moves and changes. If users move to a different subnetwork, the
addresses of each host must be updated manually. With a VLAN setup, if a host originally on the Marketing
VLAN, is moved to a port on another part of the network, and retains its original subnet membership, you
only need to specify that the new port is on the Marketing VLAN. You do not need to do any re-cabling.
