Chapter 2 14 3 Installing and connecting Installing the system in the rack This section includes the following topics: • Installing the slide rails • Installing the IBM DeepFlash 150 in the rack • Installing the CMA Note: The following installation procedures assume IBM DeepFlash 150 installation in a square-holed rack. Note: If you are using a different type of rack, consult IBM support. WARNING! To prevent bodily injury when mounting or servicing the IBM DeepFlash 150 in a rack, take special precautions to ensure that the system remains stable: Ensure that the rack is secured to the floor. Do not install the system in a mobile rack. Mount the system into a space in the lower half of the rack if possible. If mounting the system in a partially-filled rack, load the rack from the bottom to top with the heaviest components placed in the bottom of the rack. If the rack is provided with stabilizing devices, install them before mounting or servicing the system in the rack. The IBM DeepFlash 150 is heavy. Racks should be securely fastened to the floor or include stabilization mechanisms to prevent them from tipping over. The IBM DeepFlash 150 is approximately 39ʺ deep (measured from rear of front cabinet rail to rear extent of chassis with the CMA attached). If the IBM DeepFlash 150 is installed in a cabinet rather than an rack, the minimum interior depth of the cabinet must meet this length requirement. If the cabinet is too shallow, the rear doors of the cabinet might not close properly. If there are no other cabinet options available (deeper), the rear doors of the cabinet might need to be removed. Ensure that the rack is secure and meets the requirements given in the preceding paragraph before installing the IBM DeepFlash 150. Installing the slide rails To install the slide rails: 1. Detach the inner rail from the rail assembly: Chapter 3 15 a. Pull out the entire length of the inner rail assembly from the front side of the assembly, until the inner rail locks in the fully extended position. b. Slide the white plastic tab to release the lock (see Figure 3-1 on page 16). Figure 3-1. c. Release tab Detach the inner rail. d. Repeat steps a through c to detach the inner rail from the second rail assembly. 2. Attach the inner rails to the sides of the system: a. Align an inner rail with one side of the system so that the four keyed slots in the rail align with the four pegs on the side (see Figure 3-2 on page 16). Figure 3-2. Rail slots and pegs for attaching the inner rails b. Set the large hole of the keyed slots of the inner rail over the pegs, and then slide the rail towards the back side of the system to lock it in place on the pegs (see Figure 3-2 ). Chapter 3 16 c. Secure the inner rail to the system using one pan-head M4 screw as shown in Figure 3-3 on page 17 (the small plastic bag inside the rail box contains two inner rail mounting screws). Figure 3-3. Attaching inner rails d. Install the second inner rail to the opposite side. 3. Measure the distance between the front rack post and the rear rack post. The outer rails that install in the rack can be adjusted to accommodate rack post-to-post distances of from 25ʺ to 36ʺ with some simple adjustments. Make sure to adjust the rails to the proper distance before continuing. The rails can be adjusted to two ranges: • 24" to 28" • 29" to 36" The default rail length range is 29ʺ to 36ʺ. Note: If you need to adjust the rail length, use an 8 mm (or 5/16ʺ) wrench and a #2 Philips screwdriver to loosen or tighten the shoulder nuts and screws. 17 IBM DeepFlash 150: Hardware Installation Guide 4. To adjust the rail to a rack depth of 25ʺ to 28ʺ, refer to Figure 3-4 on page 18, and follow these steps: a. Unscrew the shoulder nuts and screws. b.

Insert CMA fixed connector 33 IBM DeepFlash 150: Hardware Installation Guide 4 Connecting SAS and power cables This section includes information on the system topology, SAS cable connections, and system power requirements. System topology For a description of the supported system topologies, see the ʺSupported configurationsʺ chapter in IBM DeepFlash 150 Best Practices Guide. Connecting SAS cables to the server For connection between an external 6 Gbps or 12 Gbps SAS HBA and the IBM DeepFlash 150, use only the following IBM cables: Two-meter cable: SDIFC-SASHM20 IBM DeepFlash 150 SAS Cable, Mini-SAS HD to Mini-SAS 2.1, 2m Three-meter cable: SDIFC-SASHM30 IBM DeepFlash 150 SAS Cable, Mini-SAS HD to Mini-SAS 2.1, 3m These cables can be ordered directly from IBM. Note: Host SAS expanders with mini-SAS connectors interface to one or more external servers through SAS cables up to three meters in length. Note: The maximum supported SAS cable length is 3 meters. There is a “service loop” used to allow the system to be pulled forward on the slide rails for service. In order to allow for full extension of the system, the service loop must be approximately 1.5 meters in length. A CMA can be attached to the rear of the system to manage the motion of the service loop, but the service loop is always required whether the CMA is used or not. Assuming you are using 3 meter SAS cables, each of which has a 1.5 meter service loop, an attached host must be located less than 1.5 meters (12U) from the system. Connecting power cables and powering up You must provide the appropriate power cables to connect the PSUs to your power distribution system. The power cable must be rated for 12A (at 110 VAC) and 5A (at 230 VAC), and have a C-13 connector at the IBM DeepFlash 150 end of the connection. The IBM DeepFlash 150 powers up when the PSU power cables are connected to the appropriate power source. Chapter 4 34 Installing software utilities Install the IFTools package on the CentOS/Ubuntu operating system on the host. Managing the IBM DeepFlash 150 ifcli is a command line interface (CLI) utility that allows you to monitor and manage the IBM DeepFlash 150. Review the IBM DeepFlash 150 CLI User Guide for more details. The RESTful Web Service provides the RESTful interface to clients that can manage or monitor the components of the IBM DeepFlash 150 enclosure. 35 IBM DeepFlash 150: Hardware Installation Guide IBM® Printed in USA GC27-8961-00
