5. Repeat for the other rail.

CAUTION   The enclosure is heavy and should be installed into or removed from a rack by two people. To avoid personal injury and/or damage to the equipment, do not attempt to lift and install the enclosure into a rack without a mechanical lift and/or help from another person. L'enclosure étant lourde, sa mise en place dans l'armoire nécessite deux personnes. Afin de ne pas vous blesser et/ou endommager le matériel, n’essayez pas de soulever et d’installer l’armoire sur une rampe sans avoir recours à un relevage mécanique et/ou à l’aide d’une autre personne. Das Gehäuse ist schwer und sollte nur von zwei Personen in einem Rack installiert werden. Zur Vermeidung von körperlichen Verletzungen und/oder der Beschädigung des Gerätes, bitte das Gehäuse nicht ohne die Hilfe einer zweiten Person anheben und einbauen. Il contenitore è pesante e dev'essere installato nel rack da due persone. Per evitare danni personali e/o all’apparecchiatura, non tentare di sollevare ed installare in un rack il contenitore senza un sollevatore meccanico e/o l’aiuto di un’altra persona. Debido a su considerable peso, la instalación del compartimento en el bastidor deben realizarla siempre dos personas. Para evitar daños personales o en el equipo, el compartimento no debe levantarse ni instalarse en el bastidor sin la ayuda de un elevador mecánico o de otra persona.

1. Lift the enclosure and slide it onto the rails from the front of the cabinet.
2. Push the system into the rack until the slam latches engage and lock the system into the rack.
   Ensure that the enclosure is flush with the front of the rack, fully seated in the cabinet, and does not slide out.

   Figure 3. Installing the system in the enclosure

   

1. If securing the system for shipment in the cabinet or in other unstable environments, locate the hard mount captive screw under each latch and tighten using a #1 Phillips screwdriver.

   Figure 4. Securing the system in the cabinet

   

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.

   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 5. Cabling the storage processors to the network

   

   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 Online Support ( https://support.emc.com/products/39949).

1. Verify that the cabinet circuit breakers are in the On position and that power is connected to the cabinet.

   Note:  No power cables should be connected to the PDUs at this time.

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. Plug each DPE power cable into each SP assembly's power supply unit.
   The power cable to SP assembly A is gray. The power cable to SP assembly B is black.
4. Secure each power cable to the system component with the cable retention bail on the power supply unit.
5. Connect the DPE to the power distribution unit as follows:
   1. Connect the power supply for SP assembly A, shown in gray, to PDU A .
   2. Connect the power supply for SP assembly B, shown in black, to PDU B.

   Figure 6. Cabling the DPE to the PDU

   

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.

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.

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.

   Figure 9. Installing the front bezel

   

1. After you power up the storage system, check the SP Fault LED.
   • If the SP Fault LED is solid blue, a management IP address has been assigned.
   • If the SP Fault LED is solid blue for three seconds and then flashes amber for one second intervals, no management IP address has been assigned. Check the connectivity between the system, the DNS server, and the DHCP server.
2. Open a web browser and access the Unisphere management interface specifying the following as a URL in the browser's address bar: serial_number.dns_zone
   where

   URL string	Description
   serial_number	Serial number of your storage system. You can find this in the packing materials that came with your system (for example, FNM00131800283). It is also on the PSNT tag on the front of the DPE.
   dns_zone	Network DNS zone on which the storage system is located (for example, mylab.emc.com).

   Based on the examples provided in this table, the URL to the storage system would be FNM00131800283.mylab.emc.com.

   Note:  If a certificate error appears, follow the instructions in your browser either to bypass the error or to install the self-signed storage system certificate. For more detail about your storage system certificate, refer to the EMC Unity Security Configuration Guide.

3. Log in with the default username and password.
   • Username: admin
   • Password: Password123#
