Install and Remove PTX10016 Cooling System Components

 

The PTX10016 router has two independent, field-replaceable fan trays. To install or remove the fan trays and fan tray controller, read the following sections.

Install a PTX10016 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, JNP10016-FAN and the JNP10016-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 you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.

  • Ensure that you have the following parts and tools available to install a fan tray in a PTX10016 router:

    • 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 PTX10016 fan tray (JNP10016-FAN, or JNP10016-FAN2):

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to one of the ESD points on the chassis (see Figure 1 ).

  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 the screws are finger tight. See Figure 2 and Figure 3.

The PTX10016 chassis has 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 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 PTX10016 router:

    • 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 a PTX10016 fan tray (JNP10016-FAN or JNP10016-FAN2):

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to one of the ESD points on the chassis (see Figure 4.

  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.

Install a PTX10016 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 PTX10016 (JNP10016-FAN-CTRL and JNP10016-FTC2). See Figure 7 and Figure 8.

Caution

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

In order to install 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 install a fan tray controller:

To install a fan tray controller:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to one of the ESD points on the chassis (see Figure 9.
