Fru Panel - Juniper PTX1000 Hardware Manual

You manage the PTX1000 by using the Junos OS CLI, which is accessible through the console and
out-of-band management ports on the management panel. In addition, the management panel has system
status LEDs that alert you to minor or major alarms or other issues with the router, external clock
synchronization ports, and a USB port to support software installation and recovery.

The cooling system in a PTX1000 consists of three 80-W fan modules that operate at 150 cubic feet per
minute (CFM) at full speed as well as fans housed in the power supplies. Each fan module has dual
counter-rotating fans. These fan modules can be hot-swapped—you do not need to power off the router
or disrupt routing function to replace a fan module.
In the PTX1000 cooling system, cool air enters through the vents in the port panel and hot air exhausts
through the FRU panel. This type of airflow is known as airflow out or port-to-FRU airflow.
The PTX1000 has four 1600-W power supplies, either AC or DC depending on your configuration. Each
power supply provides 12-VDC output with a standby voltage of 12 VDC. The power supplies can be
hot-swapped—you do not need to power off the router or disrupt routing function to replace a power
supply
