Reinstalling TX Matrix Plus Components After Installing the Chassis

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

1. Reinstalling the Rear Fan Trays
2. Reinstalling the Power Supplies
3. Reinstalling the TXP-F13 SIBs
4. Reinstalling the Front Fan Trays
5. Reinstalling the Host Subsystems
6. Reinstalling the TXP-F2S SIBs

Reinstalling the Rear Fan Trays

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
2. Grasp the fan tray by its handles and insert it straight into the chassis.
3. Tighten the captive screw on the bottom of the fan tray faceplate to secure it in the chassis, using a Phillips (+) screwdriver, number 2.

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 the circuit breakers on the power supply faceplate to the OFF position (O).

   Note: We recommend this precaution even though the power supplies are not connected to power.

3. Using both hands, slide the power supply into the chassis until you feel resistance (see Figure 2).
4. Twist the ejector handles at the upper corners of the power supply faceplate clockwise until they stop.
5. Slide the power supply input tray into the power supply.
6. Push the metal handle of the input power tray up toward the power supply.
7. Fasten the input power tray to the power supply using the two captive screws. Use a Phillips screwdriver, number 2.
8. Repeat the procedure for the other power supply.

Reinstalling the TXP-F13 SIBs

To reinstall the TXP-SIBs (see Figure 4):

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 TXP-F13 SIB and one hand around the top of the TXP-F13 SIB faceplate.

   Caution: When the TXP-F13 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 TXP-F13 SIB card cage in which you plan to install the TXP-F13 SIB.
4. Lift the TXP-F13 SIB into place, and carefully align the left and right edges with the guides inside the card cage.
5. Carefully slide the TXP-F13 SIB all the way into the card cage until you feel resistance.
6. Simultaneously turn both left and right ejector handles clockwise to seat the TXP-F13 SIB.
7. Repeat the procedure for the remaining TXP-F13 SIBs.

Reinstalling the Front Fan Trays

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
2. Grasp the fan tray by its handles and insert it straight into the chassis.
3. Tighten the captive screws on each side of the fan tray faceplate to secure it in the chassis, using a Phillips (+) screwdriver, number 2.
4. Repeat the procedure to reinstall the remaining fan tray.

Reinstalling the Host Subsystems

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point.
2. Carefully align the bottom and then the top edges of the host subsystem with the guides inside the chassis.
3. Slide the host subsystem into the chassis, carefully ensuring that it is correctly aligned.
4. Grasp both ejector handles and press them inward to seat the host subsystem until the ejectors latch into the faceplate.
5. Repeat the procedure to reinstall the remaining host subsystem.

Reinstalling the TXP-F2S SIBs

To reinstall the TXP-F2Ss (see Figure 7):

Caution: Be prepared to support the weight of the TXP-F2S (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. Lift the TXP-F2S SIB into place and carefully align first the bottom, then the top of the TXP-F2S SIB with the guides inside the card cage.
3. Carefully slide the TXP-F2S SIB all the way into the card cage until you feel resistance.
4. Seat the TXP-F2S SIB by grasping the ejector handle and rotating the ejector handle inward until the ejectors latch into the faceplate.
5. Repeat the procedure for each of the remaining TXP-F2S SIBs.
