Power Requirements For Ptx5000 Components - Juniper PTX5000 Hardware Manual

• If a power supply fails, Junos OS can bring low-priority FPCs offline to allow high-priority
FPCs to remain online.
For more information about configuring power management on the PTX5000, see
Power Management on the PTX5000

Power Requirements for PTX5000 Components

Table 1 describes the output power requirements for the required and optional FRUs for the PTX5000.
The power requirements vary depending on the ambient air temperature for your installation.
NOTE: The power requirements listed below are accurate for estimating typical power
consumption at different ambient temperatures. However, Junos OS reserves additional power in
the power budget for base system components—the host subsystem, the fan trays, and the SIBs.
When planning for the minimum required PSMs, this power reserve must be included.
You can use the interactive Power Calculator application at
calculator/ to determine the number of PSMs required to support your system configuration. The
Power Calculator application requires Juniper.net login credentials.
