Setting Up the Storage System Consider the following best practices when setting up an SC7020 series storage system. • Dell recommends that you use a dedicated SAN network for data transmission when using a Fibre Channel or iSCSI storage system. • Always configure redundant data paths to provide alternate paths to and from the host server should one of the data paths become disabled.
WARNING: Laser radiation, avoid direct exposure to beam. The unit is certified in the U.S. to conform to the requirements of DHHS 21 CFR, chapter 1 Subchapter J for Class I (1) laser products, and elsewhere is certified as a Class I laser product conforming to the requirements of IEC 60825-1:2007. Class I laser products are not considered to be hazardous.
Installation and Configuration Before you begin installation, make sure that the site where you plan to install the storage system has standard power from an independent source or a rack power distribution unit with a UPS. In addition, verify that there is a 3U space in the lower 20U of the rack to install the storage system. If you plan to install the storage system above the lower 20U of a rack, a customer-provided mechanical lift must be used to avoid injury.
Install the Storage System in a Rack Install the storage system and other Storage Center system components in a rack. About this task Mount the storage system and expansion enclosures in a manner that allows for expansion in the rack and prevents the rack from becoming top‐heavy. The SC7020 series storage system ships with a ReadyRails II kit. The rails come in two different styles: tool-less and tooled.
Figure 2. Attach the Rails to the Rack 3. Engage the back end of the rail until it fully seats and the latch locks into place. 4. Engage the front end of the rail until it fully seats and the latch locks into place. 5. Align the system with the rails and slide the storage system into the rack.
Figure 3. Slide the Storage System Onto the Rails 6. 8 Lift the latches on each side of the front panel and tighten the screws to the rack.
Figure 4. Tighten the Screws If the Storage Center system includes expansion enclosures, mount the expansion enclosures in the rack. See the instructions included with the expansion enclosure for detailed steps. Install the Front Bezel Install the bezel on the front of the storage system. 1. Hook the right end of the bezel onto the storage system.
Figure 5. Front Bezel 2. Insert the left end of the bezel into the securing slot until the release latch snaps into place. 3. Secure the bezel with the keylock. Connect the Power Cables Connect power cables to the storage system. 1. Make sure that the power switches are in the OFF position before connecting the power cables. 2. Connect the power cables securely to both power supply/cooling fan modules in the storage system chassis.
Figure 6. Connect the Power Cables 3. Use the straps to secure the power cables to the storage system chassis. Figure 7. Secure the Power Cables 4. Plug the other end of the power cables into a grounded electrical outlet or a separate power source such as an uninterrupted power supply (UPS) or a power distribution unit (PDU).
