    Cable and power up your storage system components

    Attach the storage processors to the network

    Procedure
    1. Locate two bulk Category (CAT) 5, 5e, 6, 6a or better Ethernet cables.
    2. Connect two Ethernet cables from the LAN to the 1 Gb RJ45 management ports from which you will configure the system. This will be one port on each storage processor. See Figure 1.
      Note:  The SP A and SP B network management ports must be connected on the same subnet. In general, both SPs should have mirrored configurations in order to provide failover.
      Figure 1. Cabling the storage processors to the network
    3. Attach Ethernet and/or Fibre Channel cables to the DPE ports, whether those built in to each SP or those on an I/O module, that you wish to use in order to create interfaces.
      This step is optional and can be done at a later time. Only the management network cables installed in the previous step are required at this time.
      Note:  Additional information about the ports and cabling is in the Hardware Information Guide, available on the Unity Info Hub at http://bit.ly/unityinfohub or on EMC Online Support ( https://support.emc.com/products/39949).

    DPE power up

    Before you begin

    All components must be racked and the network cabling completed before connecting the storage system to power and booting the system. Ensure that CNA ports 4 and 5 on the SPs are populated with the appropriate SFP type or active TwinAx connectors. Depending on the type of SFP used, the CNA ports will persist either as Ethernet or Fibre Channel, and once the protocol is set, it can only be changed by re-initializing the system.

    Procedure
    1. Verify that the cabinet circuit breakers are in the On position and that power is connected to the cabinet.
    2. Attach a double-sided Shut Down Procedure cable label to each power cable using the tie wraps included in the Accessory Kit.
      Note:  Attach each label close to the end of the power cable where it plugs into the DPE.
    3. For each DPE power cable (shown as cables 1 and 2 in Figure 2), plug the cable into the system component.
      The power cable to Power Distribution Unit (PDU) A is black. The power cable to PDU B is gray.
      Figure 2. Power cables to the DPE and optional DAEs
    4. Secure each power cable to the system component with the cable retention bail (moveable metal clip) on the component.
    5. Connect the power to the DPE. Plug the free end of the power cables into the PDU. Connect the power supply for SP A (shown as cable 1 in Figure 2) to PDU A . Connect the power supply for SP B (shown as cable 2 in ) to PDU B.
    6. Bundle and secure the cables as necessary with tie wraps.
    7. If your storage system has been installed in a cabinet, place the single-sided adhesive backed Shut Down Procedure label included in the Accessory Kit on the back of the cabinet door. Otherwise, place this label in a location that is visible while viewing the storage system from the rear.
    8. Monitor the system as it powers up. It takes approximately 10-15 minutes for the system to power up. The LEDs show the progress of system activation. Green, blue, and amber activity lights blink during the startup sequence. Review the next section for information on the power up states.

    Verify status LEDs

    The system should be available in approximately 15 minutes.

    This section calls out only the LEDs that you need to verify to ensure that the system powered up correctly.

    Note:  The Unity Hardware Information Guide provides more details on all system LEDs.

    The array is powered up and ready to run the Connection Utility once the SP Fault LED shows intervals of amber for one second and blue for three seconds. If the system is on a network with a DNS server and DHCP, the management IP address can be assigned automatically. When it is assigned, the SP Fault LED will be solid blue. Ensure that the power-up is complete and that the system is ready before you continue.

    DPE rear status LEDs

    Verify that the storage system is up and running without error using the rear facing physical indicators on the storage processor as shown in Figure 3 and Table 1.

    Installing the front bezel

    CAUTION  Remove the plastic protective strip from the front of the bezel prior to placing the system into operation. Failure to do so will cause the system to overheat.
    Procedure
    1. If present, remove the plastic protective strip from the front of the bezel.
    2. Align the bezel with the enclosure.
    3. Gently push the bezel into place on the cabinet until it latches.
    4. If the bezel has a lock, insert the key that shipped with your enclosure into the lock, and turn the key to lock the bezel.
