The 7700 drive cage expansion kit consists of 2 LCCs, 2 SSDs, and 30 HDDs. The expansion kit can be installed while the storage controllers are running.

To avoid excessive loss of cooling air during the following procedure, remove only one filler panel at a time, then immediately insert the new component. Oracle's Sun ZFS Storage appliance software automatically detects and configures each new component. The LCC, SSD, or HDD appear in the BUI Maintenance > Hardware screen when you view details for the system controller.

  1. Follow the electrostatic discharge safety practices to avoid damaging the system or components.

  2. To install an LCC, remove one of the LCC filler panels by squeezing the plastic handles, and rotating the handles out to unlock the filler panel.

  3. Remove the filler panel, and immediately insert an LCC in the slot.

  4. Install the second LCC is the same manner.

  5. Install an SSD in drive slot 30.

    Press the release button on the drive filler panel.

    Remove the filler panel from the slot.

    Press the release button on the SSD to open the latch.

    Slide the SSD into the slot, until it is fully seated.

  6. Install the second SSD in drive slot 31.

    Note: There is an exception to this step if an existing drive cage in the 7700 cabinet does not have any SSDs. In this case, install the SSD in drive slot 30 of the 7700 drive cage that does not have SSDs.

  7. Install the HDDs in drive slots 0 through 29, in the same manner as for the SSDs.

    Note: Disk slots 30 and 31 are reserved exclusively for SSDs. Do not put an HDD in slot 30 or 31.
