Problems When Hot-Plugging:
When installing CPSW2 modules into an already powered-on
8265, the following problems will occur if the power control jumper is in the incorrect position:
1. If the jumper is set to the ON (up) position, and you do not have a Controller module installed:
Ÿ
The LEDs on the CPSW2 module will not illuminate, even when the TEST LED button is pressed.
Ÿ
Media modules cannot be connected to the network or enabled.
To resolve this problem you must:
a. Power off the 8265.
b. Either:
Ÿ
Install a Controller module should you not wish to use the integrated power control of the
CPSW2 module, or
Ÿ
Remove the CPSW2 module and move the jumper to the OFF (down) position. Then re-install
the module
c. Power on the 8265.
2. If the jumper is set to the OFF position, but a Controller module is already installed:
a. Power off the 8265.
b. Either:
Ÿ
Install a Controller module should you not wish to use the integrated power control of the
CPSW2 module, or
Ÿ
Remove the CPSW2 module and move the jumper to the OFF (down) position. Then re-install
the module
c. Power on the 8265.
Ÿ
The CPSW2 module cannot take over power control from the Controller module.
Ÿ
Media modules cannot be connected to the network or enabled.
To resolve this problem you must:
a. Power off the 8265.
b. Either:
Ÿ
Remove the Controller module, should you wish to use the integrated power control functions
of the CPSW2 module, or
