c. Attach the cable management bracket (tailgate) to the stiffenerd. Make sure that the extender is available for installation after all cables have been installed4. Make sure that all nodes have a rear shelf installed and that each shelf has a tie base installed (referto Figure 2)1 Rear Node Shelf2 Tie Base5. Route all HMC, Ethernet, I/O, and switch cables up through the tailgateNote: Main power cables do not pass through the tailgate assembly6. Separate the HMC, Ethernet, I/O, and switch cables into groups for nodes on the left side of the frameand for nodes on the right side of the frameNote: Switch cables must not be connected to SNIs or switch port connection cards until the cableweight is supported at the tailgate and by a tie base mounted to a rear node shelf.7. Continue the cable installation procedure with the nodes on the “Cable Installation Procedure, Nodeson the Left Side of the Frame” of the frameCable Installation Procedure, Nodes on the Left Side of the FrameBefore starting this part of the procedure:v Be aware that this part of the procedure applies to nodes located on the left side of the frame (asviewed from the rear) and must be performed before you begin to cable the right side of the framev Make certain that all HMC, Ethernet, I/O, and switch cables are inside the cable management bracket(tailgate)v Arrange all cables for nodes on the left side of the frame into a group near the left side of the cablemanagement bracketv Arrange all cables for nodes on the right side of the frame into a group near the right side of the cablemanagement bracketNote: Do not connect any switch cables to the nodes until instructed to do so.After the preliminary steps are complete for cabling the left side of the frame:1. Route the HMC and Ethernet cables to the appropriate nodes and connect each cablev Make certain the HMC and Ethernet cables do not interfere with the SNI ports2. Wire tie the HMC and Ethernet cables into a bundle running down the left side of the frame3. Clamp the HMC and Ethernet cables into the first tailgate slot using a tailgate insert (refer to Figure 3on page 164)12Figure 2. Tie baseAppendix H.
