Reinstalling the TX Matrix Components

After the TX Matrix router is installed in the rack, you reinstall the removed components before cabling, booting, and configuring the TX Matrix router. These procedures describe how to reinstall components in the chassis, first in the rear and then in the front:

1. Reinstalling the Rear Fan Tray
2. Reinstalling the TX-CBs
3. Reinstalling the Power Supplies
4. Reinstalling the TX-SIBs
5. Reinstalling the Front Fan Trays

Reinstalling the Rear Fan Tray

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site.
2. Grasp the fan tray by its handles, and insert it straight into the chassis.
3. Tighten the captive screws on the top and bottom of the fan tray faceplate to secure it in the chassis.

Reinstalling the TX-CBs

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site.
2. Ensure that the ejector handles are not flush with the faceplate. If necessary, loosen the captive screws and flip the ejector handles outward.
3. Carefully align the sides of the TX-CB with the guides inside the chassis.
4. Slide the TX-CB into the chassis, carefully ensuring that it is correctly aligned.
5. Grasp both ejector handles, and press them inward to seat the TX-CB.
6. Tighten the captive screws on the ejector handles, using a Phillips (+) screwdriver, number 2.
7. Repeat the procedure to reinstall the remaining TX-CB.

Reinstalling the Power Supplies

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site.
2. Switch both circuit breakers on the power supply faceplate to the off position (O).
3. Using both hands, slide the power supply into the chassis until you feel resistance.
4. Twist the ejector handles at the upper corners of the power supply faceplate clockwise until they stop.
5. Tighten the captive screws at the lower corners of the power supply faceplate to secure the power supply in the chassis.
6. Repeat the procedure for the other power supply.

Reinstalling the TX-SIBs

Caution: Be prepared to support the weight of the TX-SIB (approximately 35 lb [15.9 kg])  before you lift it.

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site.
2. Place one hand under the bottom edge of the TX-SIB and one hand around the top of the TX-SIB faceplate.

   Caution: When the TX-SIB is out of the chassis, do not hold it by its ejector handles or edge connectors. They cannot support its weight.

3. Locate the slot in the TX-SIB card cage in which you plan to install the TX-SIB.
4. Lift the TX-SIB into place and carefully align first the bottom, then the top of the TX-SIB with the guides inside the card cage.
5. Carefully slide the TX-SIB all the way into the card cage until you feel resistance.
6. Starting with the ejector handles on the top and bottom of the TX-SIB faceplate nearly horizontal, simultaneously turn both ejector handles clockwise to seat the TX-SIB.
7. Repeat the procedure for each of the remaining TX-SIBs.

Reinstalling the Front Fan Trays

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site.
2. Grasp one of the fan trays by its handles, and insert it straight into the chassis.
3. Tighten the captive screw on each side of the fan tray faceplate to secure it in the chassis.
4. Repeat the procedure to reinstall the remaining fan tray.
