How to fix PWR or Status LED flashing on Comtrol Switch?
A flashing PWR or Status LED on your Comtrol Switch indicates that the bootloader has not downloaded to the DeviceMaster. To resolve this: 1. If applicable, remove the NS-Link driver. 2. Ensure you have the latest driver from http:// downloads.comtrol.com/dev_mstr/rts/drivers/. 3. Install the latest driver and configure the DeviceMaster using the MAC address. Reboot the system after.
What to do if PWR or Status LED is not lit on Comtrol Switch?
A PWR or Status LED that is not lit on your Comtrol Switch indicates that power has not been applied or there is a hardware failure. Contact Technical Support.
Why does my Comtrol Switch DeviceMaster continuously reboot when connected to some Ethernet switches?
The continuous rebooting of your Comtrol DeviceMaster Switch when connected to some Ethernet switches is often due to the Spanning Tree Algorithm (STA), an L2 bridging feature. To resolve this, you can try the following: * Disable STA in the switch. * Enable STA fast forwarding on the port. * Change the STA Forward Delay and Message Age to minimum time values. * On the device, set the time-out value to 0 (to disable loading of SocketServer) or 120. The command from the redboot prompt is 'Timeout 120' without the quotes.
How to fix 'Cannot ping or connect to the Comtrol Switch DeviceMaster'?
The default IP address of the Comtrol DeviceMaster Switch may not be accessible if your network doesn't use 192.168 due to subnet masking. You will likely need to program an address that matches your network. To do this, use PortVision DX to program the IP address. See Configuring the Network Settings on Page 38.
What to do if I cannot ping the Comtrol Switch device through Ethernet hub?
To resolve the issue where you cannot ping the Comtrol Switch DeviceMaster through an Ethernet hub, isolate the DeviceMaster from the network by connecting the device directly to the NIC in the host system.
Why does my Comtrol DeviceMaster DM-2000 continuously reboot when connected to some Ethernet switches?
The continuous rebooting of the Comtrol Server when connected to certain Ethernet switches is due to the Spanning Tree Algorithm (STA), a L2 bridging feature enabled by default in some switches. To resolve this: disable STA in the switch; enable STA fast forwarding on the port; change the STA Forward Delay and Message Age to minimum time values; or on the device, set the time-out value to 0 (to disable loading of SocketServer) or 120 using the command “Timeout 120” from the redboot prompt.
How to fix Comtrol DeviceMaster DM-2000 Server when I cannot ping or connect to the DeviceMaster?
If you cannot ping or connect to the Comtrol Server DeviceMaster, the default IP address may not be accessible due to subnet masking from another network, unless 192.168 is used in the network. In most cases, you will need to program an address that conforms to your network. If you don't use the NS-Link driver to program the IP address, you have 15 seconds to disable the Bootloader with Redboot to access the setup utility. Refer to RedBoot Procedures on Page 75 for the Redboot method of programming an IP address.
What does it mean if the PWR or Status LED is flashing on my Comtrol Server?
A flashing PWR or Status LED indicates that the boot program has not downloaded to the Comtrol Server DeviceMaster. To resolve this: 1. Ensure you have downloaded the latest driver from http://www.comtrol.com/support/download.asp?partnumber=1800288. 2. Install the driver and configure the device using the MAC address, then reboot the system. 3. If you want to program an IP address into the DeviceMaster, you can use the procedure outlined in the NS-Link User Guide (Page 10). 4. Remove the NS-Link driver. Note: If the PWR or Status LED is still flashing, contact Technical Support.
