## Install an Express Module

| Caution - This procedure involves handling circuit boards that are extremely sensitive to static electricity. Ensure that you follow ESD preventative practices to avoid damaging the circuit boards.

1. Take the necessary ESD precautions.

   See Prevent ESD Damage.

2. Insert the express module into the empty express module slot.
3. Close the express module latch to lock the card in place.
4. Reconnect the cables to the express module, if necessary.
5. Determine if you replaced or installed an express module in a running server.

   - If you replaced or installed an express module in a server that is running (if you hot-swapped the express module), go to Step 6.

   - If you replaced or installed an express module in a powered-down server, power on the server using the instructions provided in Returning the Server to Operation, then go to Step 7.

6. Determine if the express module has an Attention button.

   If the express module has an Attention button, you can use that button to bring the express card online. If not, you can use the CLI to bring the express module online.

   - If the express module has an Attention button, press the button to bring the express module online. The express module's Power OK LED should go on, indicating that the module is now online. Go to Step 7.
   - If the express module does not have an Attention button, bring the module online using the CLI:
     1. At the Oracle Solaris prompt, type the `cfgadm` `-al` command to list all devices in the device tree, including the express modules:

            # cfgadm -al

        This command helps you identify the express module you installed. For example:

            Ap_id                       Type         Receptacle   Occupant        Condition
            PCI-EM0                     sas/hp       connected    configured      ok
            PCI-EM1                     unknown      empty        unconfigured    unknown
            ...

     2. Connect the express module using the `cfgadm` `-c` `connect` command.

        Example:

            # cfgadm -c connect Ap_id

        Replace `Ap_id` with the ID of the express module that you want to connect.

     3. Verify that the green Power LED is lit on the express module that you installed.
     4. At the Oracle Solaris prompt, type the `cfgadm -al` command to list all drives in the device tree:

            # cfgadm -al

        The replacement express module is now listed as connected. For example:

            Ap_id                       Type         Receptacle   Occupant        Condition
            PCI-EM0                     sas/hp       connected    configured      ok
            PCI-EM1                     sas/hp       connected    configured      ok
            ...

7. Verify the express module functionality.

   See Verify Express Module Functionality.
