Indications for Tap Mode
Operation Use the following sections to troubleshoot the Tap mode of operation.
OK Status Indicator—Tap Mode
This red/green bicolor LED indicates the status of the option module as shown
in the table below.
LINK 1 Status Indicator—Tap Mode
This green/yellow bicolor LED indicates the status of the ENET1 network port
as shown in the table below.
Status Cause Corrective Action
Off The option module is not powered or is not properly connected to the
drive. • Securely connect and ground the option module to the drive by fully
inserting it into the drive port and tightening its two captive screws to the
recommended torque.
• Apply power to the drive.
Flashing Red The option module is not communicating with the drive via DPI.
The drive is in firmware upgrade mode.
The option module has an EEPROM fault.
The network address switches have been changed since powerup.
A duplicate IP address fault has been detected.
The DHCP lease has expired.
The network address switches are set to “888.”
The network configuration (IP address, subnet mask, gateway address) is
invalid.
The User FPGA configuration is invalid.
View the option module event queue to determine which of these conditions is
present. Then, depending on the cause, take the appropriate corrective action.
Steady Red The option module is not communicating with the drive via DPI. Important: Cycle power to the drive after making any of the following
corrections:
• Securely connect and ground the option module to the drive by fully
inserting it into the drive port and tightening its two captive screws to the
recommended torque.
• Verify that the drive supports the Comm Driver.
Flashing Green The option module is establishing DPI communication with the drive. No action required. Normal behavior if no I/O is enabled.
Steady Green The option module has established DPI communication with the drive. No action required.
Status Cause Corrective Action
Off The option module is not properly connected to the network. Securely connect the option module to the network using an Ethernet cable.
Also, make sure the Ethernet cable is correctly connected to the Ethernet
connector.
Steady Green ENET1 network port has a 100 Mbps network link, but no activity. No action required.
Flashing Green ENET1 network port has a 100 Mbps network link with activity. No action required.
Steady Yellow ENET1 network port has a 10 Mbps network link, but no activity. No action required.
Flashing Yellow ENET1 network port has a 10 Mbps network link with activity. No action required.
