PowerMax 2500 stack up System shipments When a customer purchases a third party rack solution, the components are fully tested before shipping to the customer site. After testing, all test cables that connect components in manufacturing are removed. During installation at the customer site, customer support engineers remove components from the shipping rack and install them into the customer rack. All parts used to secure and organize components in the customer rack are provided in separate kits that ship with the system; these parts include: rails, cables, Velcro straps, cable management arms, bezels, filler panels, screws, and nuts. The shipping racks and packing material, when empty, are returned to Dell after the installation is complete. System configurations PowerMax 2500 systems can contain one or two engines. Dual engine systems can contain one or two DAEs. (One DAE associated with each engine or one DAE that is shared with both engines.) ● The system must be installed contiguously in the precise order shown. ● Third-party equipment may exist above or below the system. ● Customers may install third-party equipment in the unused portion of the rack. NOTE: In a single engine system, customers may want to reserve the 5U above Engine 1 to preserve the option to add a second engine-DAE pair.

A micro-HDMI adapter is required to connect the monitor to the Control Station. The type of adapter depends on the video input connector ports on the monitor. The adapter is usually one of the following: ● Micro-HDMI to HDMI System Overview 11 Internal Use - Confidential ● Micro-HDMI to VGA ● Micro-HDMI to DisplayPort (DP) Ensure that the correct adapter is available before using a crash cart onsite. NOTE: To avoid a missing hardware error, thread the micro-HDMI adapter through the bezel by removing and then replacing the bezel. 12 System Overview Internal Use - Confidential 2 Prepare for the Installation To prepare for the installation, organize crates and shipping rack contents and prepare the racks for the components. CAUTION: Do not power on the system during the installation until you are instructed to do so. Topics: • • • • • Organizing materials Prepare the racks Component placement in the rack Installation strategy Task summary Prepare for the Installation 13 Internal Use - Confidential Organizing materials Before starting the installation, organize the materials that arrived on site. There are two shipping racks for a dual-engine system: ● Engine 1 DAE 1 ● Engine 2 DAE 2 Move the covered shipping racks and tools next to the rack where the installation is taking place. Each shipping rack contains the engine and DAE components and two boxes: ● Engine Kit: Cables and bezels for all components ● Rail Kit: Engine rails and Engine and DAE cable management CAUTION: The Rail Kit can be heavy. If necessary, use two people to move it from the shipping rack. In a dual-engine system, you install the rails and a component before moving on to the next. For example, install the DAE 1 rails and DAE 1 before moving on to Engine 1. After all components are installed in the customer rack, put the cable management brackets (for the engines) and cable management arms (for the DAEs) in place. Then cable Engine 1-DAE 1 and Engine 2-DAE 2. This means you must open the Engine 2 DAE 2 shipping rack before completing the Engine 1 DAE 1 installation. Keep track of the contents in the Engine Kits from each shipping rack. Shipping racks Each shipping rack contains the necessary kits and components that are required for the engine-DAE pair. The components and kits are visible after you remove the outer packaging. Handling the shipping racks: 1. 2. 3. 4. Move the pallet close to the rack. Move the pallet with the Engine 1 DAE 1 shipping rack into position to work on first. Remove strapping from the outer packaging. Lift the outer packaging off the pallet. Flip the outer packaging upside-down to use it as a container for trash during the installation. Prepare the racks NOTE: You will need to open the Engine 2 DAE 2 shipping rack before completing the Engine 1 DAE 1 installation. Keep track of the contents in the Engine Kits from each shipping rack. ● Only uncover one shipping rack at a time. Once you have finished installing all of the components from one shipping rack, move on to the next one. ● For each shipping rack, remove the exterior cardboard packaging to expose the accessory boxes and components inside. ● On the customer's rack, remove any front and rear doors. If possible remove side panels from the rack as well. Document the removal process so you can re-install the doors and panels at the end of the installation. ● The ARES ENG 1 3RD PARTY INSTALL KIT in the Engine 1 DAE 1 shipping rack contains U-designator tape. On each rack, evaluate whether the U-designators are sufficient on the rack. If not, add the U-designator labels. ● If the NEMA rails are adjustable, Dell recommends setting the front to rear distance at 24". ● The rail width should be consistent with the National Electrical Manufacturers Association (NEMA) standard for 19-inch cabinets. ● Review Assessing the need for the NEMA rail retention bracket on page 14 to determine if the NEMA rail retention bracket is required for the installation. Make sure you review Component placement in the rack on page 16 before installing components in the rack. Assessing the need for the NEMA rail retention bracket Use the NEMA rail retention bracket to eliminate NEMA rail flexing when installing System 1 or System 2. NOTE: The NEMA rail retention bracket may or may not be available in the ARES ENG 1 3RD PARTY INSTALL KIT at the time of install. If the bracket is needed and not in the install kit, place an order for the bracket kit, PN 106-564-072, at MWD Customer Complaints Capture System. The bracket kit is shipped overnight to the site. 14 Prepare for the Installation Internal Use - Confidential Use the table below to determine if the NEMA rail retention bracket is required for the hardware installation process. Table 6. NEMA rail retention bracket location System and U-location Conditions requiring the bracket Bracket location System 3 (U27-U36) None Not required System 2 (U16-U25) No hardware is currently installed below U31. U30 System 1 (U5-U14) No hardware is currently installed below U20. U19 If you are installing System 1 and System 2 at the same time: 1. 2. 3. 4. 5. Install the NEMA rail retention bracket at U19. Install System 1. Remove the bracket and reinstall it at U30. Install System 2. Remove the NEMA rail retention bracket. Each PowerMax 2500 system must be installed in a contiguous U-space. If you are installing a system in a different contiguous U-space than what is listed above, use the following rules for the location of the NEMA rail retention bracket: ● Install the bracket at the fifth U-location above the top DAE. For example, If the top DAE in the system will be installed in U17-U18, install the bracket at U23. ● If you are installing a system at the top of the rack and there is no existing hardware below the system, install the bracket in the U-location below Engine 1. ● If there is equipment in the system U-space already, you do not need to install the bracket. Prepare for the Installation 15 Internal Use - Confidential Component placement in the rack The Base-U is the bottom U of the PowerMax 2500 system. The Base-U of each PowerMax 2500 system is: Table 7. System Base-U System Location System 3 U27 System 2 U16 System 1 U5 PowerMax 2500 systems can be installed at a different Base-U as long as the systems are serviceable at the position in the rack. There is no space separation between engines and DAEs in PowerMax 2500 systems. If installing a single-engine system, 5U above the Engine 1-DAE1 pair should be reserved for future upgrades to a two-engine, two-DAE system. NOTE: Third-party racks may include a spacer to set the depth of the rack. If the rack includes a spacer, move it to an unused U-space or remove it from the rack. Use the image and rack diagram to mark the precise placement of each component in the rack. Reference the table throughout the installation process.

If network access is not available on your laptop, use the Dell VPN to connect the Complete the Installation 59 Internal Use - Confidential system. Verify that remote client file transfer is working. If network access is not available, contact local triage or the support lab to perform the connect-in test. Validating the installation You must run the Install script before turning the system over to the customer. Before going on-site, refer to Salesforce Article Number 304108 for information on how to determine the correct installation path. Generate the relevant Enhanced Procedure Generator (EPG) procedure before going to the customer site. The Install script uses the following criteria to determine which script to run. The appropriate script will start automatically. ● Verify VMAX Setup script: Dell rack system is at the operating system level with the configuration that the system shipped with. ● C&I script: ○ Dell rack system is at a different operating system level or a different configuration than the system shipped with. ○ A second PowerMax system in a Dell rack. (Second systems are available with some PowerMax models only.) ○ Third-party rack system. Running the script Before turning the system over to the customer, run the Install script as per the EPG procedure you created. NOTE: Do not connect HOST cables until the system has completed the installation process. Validating the Firewall About this task Complete this task after successfully installing or upgrading a system. Steps 1. In Simplified SymmWin, select Scripts > Health Check. As part of the Health Check, Simplified SymmWin verifies that the WFCT is running and configured as expected. ● IF the WFCT is configured as expected, the Health Check does not return any WFCT-related errors. ● IF the WFCT is not configured as expected, the Health Check returns a call home error with a description of the error. Errors can be found in the WFCT log file: ○ PowerMaxOS 5978.xxx.xxx: O:\EMC\WFCT\wfct_data\logging.log ○ PowerMaxOS 10: O:\EMC\logs\wfct\wfct.log 2. If errors occur: a. Evaluate and resolve each error. See WFCT errors and recommended actions on page 61 and use the list of recommended actions to resolve the problem. b. Run Health Check until the logging.log (PowerMaxOS 5978.xxx.xxx) or wfct.log (PowerMaxOS 10) file displays Health Check successful. 3. If the customer requires additional Firewall Products, open the WFCT from the desktop and perform the required changes. NOTE: You must create a new configuration when a customer requires additional Firewall Products. When you create a new configuration, products that are related to a previously active configuration are copied to the new configuration. Do not add or remove anything from the DEFAULT_ACTIVE configuration. 4. Verify that the Windows Firewall is ON. See Verify that the Windows Firewall is ON on page 63. 60 Complete the Installation Internal Use - Confidential WFCT errors and recommended actions Use the table below to identify and resolve WFCT errors.
