Cable Routing Procedures for Dell™ PowerEdge™ R415 Systems Introduction This white paper covers recommended cable routing procedures for the Dell™ PowerEdge™ R415 system in the following racks: PowerEdge™ 2410 PowerEdge™ 4210 PowerEdge™ 2420 PowerEdge™ 4220 (including wide and deep versions) PowerEdge™ 4820 (including wide and deep versions) 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 discon
Cable Routing Procedures for Dell™ PowerEdge™ R415 Systems 1.2 Installing the Inner CMA Attachment Bracket As described in the Rack Installation Instructions, locate and attach the appropriate inner CMA attachment bracket based on which side you wish to mount the CMA. Use the bracket marked “A” for mounting the CMA on the left side, and the bracket marked “B” for mounting on the right side. See Figure 2. Figure 2: Attaching the Inner CMA Attachment Bracket 1.

Install the CMA on the rear left side of the rails by attaching both CMA housings to the attachment brackets on the rails. 2. Route the cables through the CMA while avoiding twisting the cables. Use the hook and loop straps on the CMA to secure the cables. See Figure 4.

Follow steps 2-6 from the left-side mounting instructions in section 1.5. See Figure 7 for an example of a completed right-side mounted CMA installation.
Cable Routing Procedures for Dell™ PowerEdge™ R415 Systems Section 2: Cabling a Dell™ PowerEdge™ R415 System Without a CMA NOTE: The CMA on Dell™ PowerEdge™ R415 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.
