General troubleshooting
B
Web UI is sluggish, does not refresh properly, or does not respond
When configuring the switch, it is easy to overlook the fact that the host computer is running the
browser while the Brocade Mobility RFS7000-GR Controller is providing the data to the browser.
Occasionally, while using the Web UI the switch does not respond or appears to be running very
slow; this could be a symptom of the host computer or the network, and not the switch itself. The
table below provides suggestions to troubleshoot this issue.
Console port is not responding
The Brocade Mobility RFS7000-GR Controller console port is connected to the host computer’s
serial port, but pressing the [Enter] key gets no response from the switch.
The table below provides suggestions to troubleshoot this issue.

switch and console system Verify the line between the switch and the host computer is functioning normally.
