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.

FRU Panel

The field-replaceable unit (FRU) panel of the PTX1000 contains the fan modules and
power supplies for the PTX1000.

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
