Identify the Parts of the Rear Cable Management System

1. Remove the rear cable management system parts from the shipping crate.
2. Identify all the parts of the rear cable management system.
   • Upper cable management shelf
   • Middle cable management shelf
   • Lower cable management shelf
   • Comb assembly
   • Comb assembly left support
   • Comb assembly right support
   • Two left cable management arms
   • Two right cable management arms
   • 24 Phillips screws provided in the accessory box.
   • Velcro straps provided in the accessory box.

Installing the Rear Cable Management System Comb Assembly

1. Assemble together the left and right comb assembly supports with the comb panel assembly with the four of the supplied Phillips screws.
2. Align the four captive screws on the comb assembly with the mounting holes at the top of the chassis (immediately above the TXP-F13 SIB card cage). Secure the cable assembly to the chassis to the top of the chassis by tightening each of the captive screws.

Installing the Rear Cable Management System Shelves

1. Identify the top, middle, and bottom shelf. They can be differentiated visually, or by the position of the keying pin.
   • Visual: The three shelves differ in the appearance of the pivoting arms protruding from the sides of the shelves.

   • Key pin position:

     • A: Upper shelf key pin position
     • B: Middle shelf key pin position
     • C: Lower shelf key pin position
2. Familiarize yourself with the pivoting bracket mechanism. Each cable management shelf has two or four pivoting brackets which hold the cable management arms. Each bracket has a release tab. Pressing this tab will allow the bracket to be pivoted and lock into an alternative position. The two locking positions are termed: normal position, and service Position.
3. Orient the shelf so that the keying pin location is toward the right side of the shelf. Align the long guide pins with the holes in the chassis, and slide the shelf into place. Fully tighten the captive screws on the left and right sides of each shelf

   Note: It is easiest to tighten these screws if the pivoting arm brackets are in the service position.

4. Repeat for the remaining shelves.

Installing the Rear Cable Management System Arms

1. Identify the left cable management arms and right cable management arms.
2. Attach each cable management arm with three screws on top and three screws on bottom of each arm.
3. Move the upper and lower brackets for the upper right cable management arm into the service position. Repeat for the lower right cable management arm, and for both left cable management arms.
4. Position one of the right cable management arms onto the brackets, and install with three of the supplied Phillips screws into the upper bracket, and three of the supplied Phillips screws into the lower bracket.
