Cable Routing Procedures for Dell™ PowerEdge™ R815 Systems Introduction This white paper covers recommended cable routing procedures for Dell™ PowerEdge™ R815 systems in the following racks: • • PowerEdge™ 4820/4220/2420 PowerEdge™ 4210/2410 If you are using the optional CMA, following these procedures will allow you to extend the system from the rack for service without powering down or disconnecting the cables.
Cable Routing Procedures for Dell™ PowerEdge™ R815 Systems 1.2 Routing the Power Cables Through the Strain Reliefs After you have installed the tray and cables, route the power cables through the strain reliefs located on the power supply handles as shown in Figure 2. Figure 2: Routing Power Cables Through the Strain Reliefs 1.3 Routing the Cables Through the CMA You can install the CMA on either the rear right or rear left side of the rails.
Cable Routing Procedures for Dell™ PowerEdge™ R815 Systems Figure 3: Routing the Cables Through the CMA NOTE: Do not store excess cable slack inside the CMA. The cable may protrude through the CMA, thus causing binding and potentially damaging the cable. Cables entering the CMA should have a small amount of slack to avoid cable strain when the CMA is extended. KVM dongle placed inside the basket for Left-Side Mounting.

Install the CMA on the rear right side of the rails by attaching both CMA housings to the attachment brackets on the rails. Route the cables through the CMA while avoiding twisting the cables. Use the hook and loop straps on the CMA to secure the cables.
Cable Routing Procedures for Dell™ PowerEdge™ R815 Systems Section 2: Cabling a Dell™ PowerEdge™ R815 System Without a CMA NOTE: The CMA on Dell™ PowerEdge™ R815 systems is optional. Without the CMA installed, the system must be powered down and all cables disconnected before it can be removed from the rack. 2.1 Routing the Cables 1. Connect all applicable cables to the rear of the system and verify that all connections are secure. 2.
