The Unit View shows a TP connector with a red cable. This
particular 100Mbps connection has been downgraded to a 10Mbps
connection by the Smart auto-sensing feature (indicated by the red
cable), as it a poor quality connection and performs better at
10Mbps. The reason for the poor quality may be the use of incorrect
or damaged cables (Category 5 twisted-pair is required for Fast
Ethernet), or that the connection travels through many patch panels
before reaching the attached device.
The error message ‘Incorrect user access level’ is displayed on
the web interface page. You are trying to perform a management
operation that is not permitted for your user level.
The Cascade Module icon is not shown on the side bar, when a
different unit or stack is connected with a Cascade Converter
Kit. When you make the connection to the Dual Speed Hub stack, it
may take 30 seconds to register the connection. If the Cascade
Module icon is not present, you may need to reload the web
interface page on your Web browser, or (if this does not work) close
the Web browser and reconnect to the web interface. If the Cascade
Module icon is still not shown, the Cascade Module may be fitted
incorrectly.
Cannot access an attached unit or stack with the Cascade
Module Attached Unit(s) page. Ensure that the IP address
specified in the IP Address field matches the IP address of the
attached unit or stack. The management module within the attached
unit or stack may be fitted incorrectly.
After changing the password, the Web browser displays a
message informing you that it can no longer access the stack.
This is because the Web browser is still using the old password. If you
click OK to accept the message, the password panel appears so you
can enter the new password to re-access the stack.
You forget your password. If you can access the stack using the
security or admin user level, you can initialize the stack to reset the
passwords. If you have forgotten all of your passwords, you must
contact your supplier.
