Specific CPSW2 Module Problems
Problems may occur when a CPSW2 module is installed with an incorrect power control jumper (FORCE
RCTL) setting. The setting is incorrect if:
The jumper is set to ON (up) and no controller module is installed.
The jumper setting differs from that of an already installed CPSW2 module.
The problems may occur:
after powering on the 8265
when inserting the CPSW2 module while the 8265 is powered on (hot-plugging).
To avoid these problems, you must ensure that the jumper setting on the CPSW2 module being installed
is correct, and, if applicable, matches that of the currently installed module. To check the current setting
on the active CPSW2 module without removing the module, enter the SHOW POWER ALL command.
Problems After Power-On
1. If a CPSW2 is installed with the FORCE RCTL jumper set to ON (up), and no Controller module is
installed:
The LEDs on the CPSW2 module will not illuminate, even when the TEST LED button is pressed.
Media modules cannot be connected to the network or enabled.
To resolve this problem you must:
a. Power off the 8265.
b. Either:
Install a Controller module should you not wish to use the integrated power control of the
CPSW2 module, or
Remove the CPSW2 module and move the jumper to the OFF (down) position. Then re-install
the module
c. Power on the 8265.
2. When two CPSW2 modules are installed with different jumper settings:
If the active CPSW2 module has an incorrect jumper setting:
– The LEDs on the (newly) active CPSW2 module will not illuminate, even when the TEST LED
button is pressed.
– Media modules cannot be connected to the network or enabled.
This occurs regardless of the setting on the second (standby) CPSW2 module.
If the standby CPSW2 module has an incorrect jumper setting:
– The 8265 will be operational provided that the active CPSW2 module's jumper position in the
correct (ON if Controller module installed). However, the 8265 will not be able to switch to the
backup CPSW2 module. When this is attempted:
- The LEDs on the (newly) active CPSW2 module will not illuminate, even when the TEST
LED button is pressed.
- Media modules cannot be connected to the network or enabled.
Should this problem occur, you must
a. Power off the 8265
