Installing the Controller Module
Controller modules are only required when the standard CPSW module is to be used (Controller module
functionality is in-built in the enhanced CPSW2 module). Controller modules may be installed in
conjunction with a CPSW2 module if you prefer power management to be handled by the Controller
module instead of the CPSW2 module. When using Controller modules with CPSW2 module(s), the
FORCE RCTL jumper on the CPSW2 module(s) must be set to the ON position (see ,Figure 15 on
page 29 for the jumper location).
The 8265 Controller modules must be installed in the Controller module slots. These slots are located at
the lower right front corner of the switch, slot 18 (left) and slot 19 (right). Controller modules are not
designed for installation in any other slot.
The 8265 Controller module bay accommodates up to two Controller modules. Install at least one
Controller module for normal 8265 operation. Install a second Controller module to achieve Controller
module fault-tolerance.
Note: The second Controller module can only act as a backup for another Controller module. It cannot
act as a backup for a CPSW2 module using integrated power control.
Considerations When Installing Two Controller Modules
When two controller modules are to be installed, which module becomes the active depends on whether
the 8265 is powered on or not.
Ÿ
If the 8265 is not powered on, the controller module installed in slot 18 will become the active one
(and the module in slot 19 will become the standby module) when the 8265 is powered on, regardless
of the order in which they are installed.
Ÿ
If the 8265 is already powered on, the first controller module to be installed will become the active
one, irrespective of the slot used. It will also remain the active one when the second module is
installed later.
Installing the Module
To install a Controller module:
1. Remove the Controller module from the shipping carton.
2. Remove the Controller module from the anti-static bag and inspect it for damage. If the module
appears to be damaged, put it back in the anti-static bag, place it in the shipping carton, and contact
your local supplier.
3. Record the serial number and software version of your Controller Module. (Once the switch is
operational, you can view this information by entering the SHOW INVENTORY command at the
terminal prompt.)
4. If the controller slot is covered by a blank faceplate, remove the faceplate by turning the two
spring-loaded screws that hold the faceplate in place, counterclockwise. The Controller bay is located
at the lower right front corner of the switch.
Note: Each 8265 Controller module is equipped with an ejector that helps you to remove the
Controller module. This ejector can be in any position when you install the Controller module.
Figure 16 on page 34 shows how to insert a Controller module.
