PTX10008 Cooling System
The PTX10008 cooling system components work together to keep all components within the acceptable temperature range. If the maximum temperature specification is exceeded and the system cannot be adequately cooled, the Routing and Control Board shuts down some or all of the hardware components.
PTX10008 Cooling System and Airflow
The cooling system in a PTX10008 chassis consists of dual fan trays with matching dual fan tray controllers.
Three fan tray models (JNP10008-FAN, JNP10008-FAN2, JNP10008-FAN3) and their associated fan tray controllers (JNP10008-FAN-CTLR, JNP10008-FTC2, JNP10008-FTC3) are available and operate in systems with either the JNP10008-SF switch fabric or the JNP10008-SF3 switch fabric. Each fan tray requires a companion fan controller to be installed and operational to be hot-insertable and hot-removable. When upgrading from a JNP10008-FAN and JNP10008-FAN-CTRL system to a JNP10008-FAN2 and JNP10008-FTC2 system, be sure to upgrade the power supplies to JNP10K-PWR-AC2 or JNP10K-PWR-DC2 to ensure adequate airflow.
All power supplies installed in the routers have internal fans that contribute to chassis cooling. The JNP10K-PWR-AC3, JNP10K-PWR-AC2, and JNP10K-PWR-DC2 power supplies play a more substantial role in cooling the chassis than the JNP10K-PWR-AC and JNP10K-PWR-DC models. Therefore, all the JNP10K-PWR-AC3, JNP10K-PWR-AC2, or JNP10K-PWR-DC2 power supplies must be present in a running chassis to have the adequate airflow. While all power supplies are required to be present in the chassis, they do not necessarily be connected to power. If a power supply is installed in a slot but not connected to a power source, it draws power from the chassis to power the internal fans in the power supplies.
Fan Trays
All three fan tray models contain an array of internal fans, a non-removable control board, and LEDs.
The two fan trays install vertically, side by side, next to the power supplies on the FRU side of the chassis. Two handles on each front faceplate facilitate handling of the fan tray. See Figure 1 and Figure 2.

Weight | 11.8 lb (5.4 kg) | 20 lb (9.07 kg) | 26 lb (11.8 kg) |
The array of fans in all the three models operate as a single unit. If an individual fan in the array fails, the entire fan tray must be replaced.
If you want to replace an existing fan tray while the router is running, remove only one fan tray. The router continues to operate for a limited time with a single operating fan tray without triggering a thermal alarm.
To avoid a thermal alarm, do not remove both fan trays while the router is operating.
The chassis will shut down if a thermal alarm is raised for more than three minutes.
The internal fan control board in each fan tray contains the LEDs for the associated fan tray controllers and the LEDs for the three SIBs directly behind the fan tray.
Fan Tray Controllers
The PTX10008 supports two fan tray controllers to provide the control logic and power to hot-insert and hot-remove a fan tray.
There are three fan tray controller models:
JNP10008-FAN-CTRL—Supports model JNP10008-FAN; see Figure 4.
JNP10008-FTC2—Supports JNP10008-FAN2 fan tray; see Figure 5.
JNP10008-FTC3—Supports JNP10008-FAN3 fan tray.

The system continually monitors the temperature of critical parts across the chassis and adjusts the chassis fan speed according to the temperature.
Junos OS software controls the fan speed.
Under
normal operating conditions, the fans in the fan tray run at less than full
speed. If one fan tray controller fails or appears
missing (such as when a SIB is being replaced), the other fan tray
controller sets the fans to full speed. This allows the router to continue
to operate normally as long as the remaining fans cool the chassis
sufficiently. Use the show chassis fan command to see the
status of individual fans and fan speed. The following examples of the
show chassis fan command show the fan status for a
system running JNP10008-FAN and JNP10008-FAN-CTRL:
This example shows the output from a JNP10008-SF fabric system running JNP10008-FAN and JNP10008-FAN-CTRL and standard Junos OS.

Airflow Direction in the PTX10008
The air intake to cool the chassis is located on the port (line card) side of the chassis. Air flows into the chassis from the ports in the RCBs and line cards, through the Switch Interface Boards (SIBs), and exits from the fan trays and the power supplies. See Figure 6.
The fan tray continues to operate indefinitely and provide sufficient cooling even when a single fan fails, provided the room temperature is within the operating range. You can check the status of fans by viewing the LEDs on each fan tray. See PTX10008 Fan Tray LEDs and Fan Tray Controller LEDs.
You cannot replace a single fan. If one or more fans fail, you must replace the entire fan tray.
In addition to the fans in the fan trays, there is an internal fan in each power supply that also helps to cool components, such as the line cards.
