Removing and Installing PTX10000 Cooling System Components

 

Both PTX10008 router and PTX10016 routers have two independent, field-replaceable fan trays. To install or remove the fan trays and fan tray controller, see the following sections.

Installing a PTX10000 Fan Tray

Each fan tray is a hot-removable and hot-insertable field-replaceable unit (FRU); you can remove and replace the fan tray while the router is running without turning off power to the router or disrupting routing functions. There are two models of the fan tray, JNP10008-FAN and JNP10008-FAN2.

Each fan tray is installed vertically on the rear, or FRU-side, of the chassis.

Before you begin to install a fan tray:

Ensure that you have the following parts and tools available to install a fan tray in a PTX10000:

  • Electrostatic discharge (ESD) grounding strap

  • A Phillips (+) screwdriver, number 1 or 2 (optional), for the captive screws

  • A replacement fan tray

Caution

The fan tray can be removed and replaced while the router is operating. However, the fan tray must be replaced within three minutes of removing the fan tray to prevent the chassis from overheating.



To install any PTX10000 fan tray (JNP10008-FAN, ,JNP10008-FAN2, JNP10016-FAN, or JNP10016-FAN2 fan tray):

  1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the rear left side of the chassis (see Figure 1 and Figure 2 ).

  2. Grasp the top and bottom fan tray handles and align the bottom of the fan tray with the bottom of the fan tray slot.
  3. Rest the bottom edge of the fan tray in the slot and slide the fan tray into place so it is fully seated.
  4. Tighten the captive screws until finger tight. See Figure 3 through Figure 6.

Removing a PTX10000 Fan Tray

The PTX10008 chassis and the PTX10016 chassis have two independent, field-replaceable fan trays. Each fan tray is a hot-removable and hot-insertable field-replaceable unit (FRU); you can remove and replace the fan tray while the router is running without turning off power to the router or disrupting routing functions. There are two models of fan tray for the PTX10008 (JNP10008-FAN and JNP10008-FAN2) and two models of fan tray for the PTX10016 (JNP10016-FAN and JNP10016-FAN2).

Caution

Do not remove the fan tray unless you have a replacement fan tray available.

Each fan tray is installed vertically on the rear, or FRU-side, of the chassis.

Before you remove a fan tray:

  • Ensure you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.

  • Ensure that you have the following parts and tools available to remove a fan tray from a PTX10000:

    • Electrostatic discharge (ESD) grounding strap

    • Replacement fan tray

    • A Phillips (+) screwdriver, number 1 or 2 (optional), for the captive screws



Caution

The fan tray can be removed and replaced while the router is operating. However, the fan tray must be replaced within 3 minutes of removing the fan tray to prevent overheating of the chassis.

To remove any model of the PTX10000 fan tray (JNP10008-FAN, JNP10008-FAN2, JNP10016-FAN, or JNP10016-FAN2:

  1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the rear left side of the chassis. See Figure 7 and Figure 8.

  2. Loosen the four captive screws either by unscrewing with your thumb and forefinger or with a Phillips screwdriver.
  3. Grasp the top and bottom handles and pull the fan tray out about 3 in. (7.6 cm). See Figure 9 and Figure 10 for the PTX10008 and Figure 11 and Figure 12 for the PTX10016.

  4. Tilt the top of the fan tray forward.
  5. Using both hands, lift the fan tray out of the slot and rest it on a flat surface with the handles to the side.Caution

    Replace a fan tray within three minutes to avoid chassis overheating.

Installing a PTX10000 Fan Tray Controller

For each of the two fan trays, there is a fan tray controller. Each controller is a hot-removable and hot-insertable field-replaceable unit (FRU); you can remove and replace one fan tray controller while the router is running without turning off power to the router or disrupting routing functions. There are two models of fan tray controller for the PTX10008, JNP10008-FAN-CTRL and JNP10008-FTC2. There are also two models of fan tray controller for the PTX10016, JNP10016-FAN-CTRL and JNP10016-FTC2. See Figure 13 and Figure 14.

Caution

Do not remove the fan tray controller unless you have a replacement controller available.

In order to access a fan tray controller, you must first remove the associated fan tray. With the fan tray removed, the fan tray controller is installed horizontally above the Switch Interface Boards (SIBs) at the top of the chassis.

Before you replace a fan tray controller:

Ensure that you have the following parts and tools available to install a fan tray controller into a PTX10000:

  • Electrostatic discharge (ESD) grounding strap

  • Replacement fan tray controller

  • A Phillips (+) screwdriver, number 1 for the captive screws

To install a fan tray controller:

  1. Remove the replacement fan tray controller from the electrostatic bag.
  2. Carefully slide the fan tray controller into the fan tray controller slot until it is flush with the mounting holes. See Figure 15 and Figure 16.
