Comtrol PortVision DX - Manual (Page 155)

PortVision DX User Guide
The RocketLinx flashes the SYS LED for five seconds.
2. If necessary, you may need to click Tracker and ON several times to catch the flashing
SYS LED.
OFF-LINE Devices
The Device List may display OFF-LINE device status for a variety of reasons. You may want to
click Refresh to see if the device displays ON-LINE.
Note: Remember, unmanaged RocketLinx switches and other hardware can be toggled
from ON-LINE to OFF-LINE using the General tab of the Properties screen.
PortVision DX can only determine whether a Comtrol Ethernet attached product is
on-line or off-line.
• The device is not powered.
• The device is in the process of booting up and may show as
ON-LINE at the next PortVision
DX request.
• The device has not completed loading firmware. If possible, check the status LED on the
Comtrol Ethernet attached product.
• A firewall is blocking communications between the device and PortVision DX.
• The device is using the same IP address as another device. If this is the case, an asterisk is
displayed behind the IP address in the Device List pane.
• Incorrect IP addressing in the device has been implemented.
• The device is getting an IP address from a DHCP server so the address is different than
what PortVision DX knows.
• A DeviceMaster is using LOCAL as the Detection Type but it is on the other side of a router
or switch that has Layer 2 MAC mode disabled and only supports Layer 3. If this is the case,
simply
change the Detection Type from LOCAL to REMOTE.
• The device is too busy to respond to the PortVision DX request for status.
• The device’s Ethernet cable is disconnected or connect into the wrong Ethernet port.
The DeviceMaster 2E/4/8/16-port models with external power supplies follow the IEEE
specifications for standard Ethernet 10/100BASE-TX topologies.
When using the UP and DOWN ports, the DeviceMaster 2E/4/8/16 is classified as a switch.
When using the UP port only, it is a simple end node device. The maximum number of daisy-
chained DeviceMaster 2E/4/8/16 units, and the maximum distance between units is based on
the Ethernet standards and will be determined by your own environment and the conformity of
your network to these standards.
