To release the lock, press the slide release latch on the side of each slide and then slide the system into the rack. 8 When you are satisfied that the cables are routed correctly, push the system fully into the rack. Attaching the Cable-Management Arm Ramp Assembly The cable-management arm ramp assembly guides the cable-management arm into a stable, level position. To attach the cable-management arm ramp assembly: 1 Select only one ramp assembly, depending on the orientation of the cable-management arm. a If the cable-management arm is attached on the right side of the rack (as shown in Figure 1-11), attach the left cable-management arm ramp assembly to the rack (see Figure 1-10). b If the cable-management arm is attached on the left side of the rack, attach the right cablemanagement arm ramp assembly to the rack (see Figure 1-10). CAUTION: The cable-management arm ramp assembly must be installed to prevent long-term sagging of the cable-management arm. NOTE: Ensure that you use the cable-management arm ramp assembly with the metal ramp facing toward the center of the rack (see Figure 1-10).
