Four-Post Rack Installation 255 Route the cables through the cable-management arm baskets.6 Adjust the cable slack as needed at the hinge position and secure the bundled cables with the verticalVelcro strap (see Figure 1-14).7 Use the preinstalled tie wraps at the inner end and hinge point of the cable-management arm to securethe bundled cables in the cable-management arm channel (see Figure 1-14).8 Close the cable basket lid.9 Unscrew the thumbscrews that secure the front of the system to the front vertical rail.10 Slide the system in and out of the rack to verify that the cables are routed correctly and do not bind,stretch, or interfere with the movement of the cable-management arm. Adjust the cable positioninginside the cable management arm as needed.NOTE: If you pull the system out to its furthest extension, the slide assemblies lock in the extended position. Torelease the lock, press the slide release latch on the side of the slide and then slide the system into the rack.11 When you are satisfied that the cables are routed correctly, push the system fully into the rack.12 Lift the cable-management arm retention latch on the tray to secure the arm (see Figure 1-14).Removing the System From the RackRemoving a System With Sliding RailsTo remove the system from the rack, perform the following procedure:1 Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.2 Remove the I/O cable connectors and power cable connectors from their respective connectors on thesystem back panel.3 Loosen the thumbscrews on each side of the front chassis panel that secures the system to the rack.4 Pull the system out of the rack until it locks with the rails in the extended position.5 Pull up on the front release latch on each rail (see Figure 1-9) and slide the system forward.6 Pull the system completely out of the rack.Removing a System With Static RailsTo remove the system from the rack, perform the following procedure:1 Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.2 Loosen the thumbscrews on each side of the front chassis panel that secures the system to the rack.3 Disconnect all cables from the system.4 Pull the system out of the rack until it stops because of the release latches.5 Push down on the release latches on each side of the system (see Figure 1-10).6 Pull the system completely out of the rack.
