Installing I/O modules

To install I/O modules, including the NVRAM/FlashCache modules from the old chassis, follow the specific sequence of steps.

Before you begin

You must have the chassis installed so that you can install the I/O modules into the corresponding slots in the new chassis.


  1. If you are not already grounded, properly ground yourself.
  2. After the replacement chassis is installed in the rack or cabinet, install the I/O modules into their corresponding slots in the replacement chassis by gently sliding the I/O module into the slot until the lettered and numbered I/O cam latch begins to engage, and then push the I/O cam latch all the way up to lock the module in place.
  3. Recable the I/O module, as needed.
  4. Repeat the preceding step for the remaining I/O modules that you set aside.
    Note: If the old chassis has blank I/O panels, move them to the replacement chassis at this time.
