Description

(EX9200 switches, MX Series 5G Universal Routing Platforms and PTX Series Packet Transport Routers only) Display power limits and usage information for the AC or DC power sources.

On EX9200 switches, MX Series, ACX7024, and SRX5800 5G Universal Routing Platforms, power is supplied by Power Entry Modules (PEMs).

Note:
The new high-capacity (4100 W) enhanced DC PEM on MX960 routers includes a new design that can condition the input voltage. This results in the output voltage differing from the input voltage. The earlier generation of DC PEMs coupled the input power directly to the output, thereby making it safe to assume that the output voltage was equal to the input voltage.
On the MX2020 Universal Routing Platforms, the power system consists of three components: the power supply modules (PSMs), the power distribution module (PDM), and the power midplane. The power feed is connected to the PDM. The PDM delivers power to the power midplane. The power midplane supplies power to the PSMs. The MX2020 router chassis provides 3+3 (2500W/80A) or 4+4 (2100W/60A) PSM redundancy for the critical FRUs with two power zones.
On the MX2010 and MX2008 Universal Routing Platforms, the power system consists of three components: the power supply modules (PSMs), the power distribution module (PDM), and the power midplane. The power feed is connected to the PDM. The PDM delivers power to the power midplane. The power midplane supplies power to the PSMs. Unlike the MX2020 router chassis, the MX2010 and MX2008 router chassis does not provide redundancy for the critical FRUs because there is only one power zone.

Starting from Junos OS Release 17.3, MX10003 routers support DC (1100W), AC High (1600W), and AC Low (800W) power supply units.
Starting from Junos OS Release 21.4R1, SRX5800 power system consists of high-capacity second-generation AC power supply module (PSM). This single or dual PSM provides a maximum output power of 5100 W. In the single-feed mode, the PSM provides power at a reduced capacity (2550 W). In dualfeed mode, the PSM provides power at full capacity (5100W). The PSM supports 1+1 redundancy.
Starting from Junos OS Evolved Release 22.3R1, ACX7024 supports single PSM mode and PSM 1+1 redundancy.
On the PTX Series Packet Transport Routers, power is supplied by power supply modules (PSMs). On PTX5000 routers, the power feeds connect to the power distribution units (PDUs).
Starting with Junos OS Release 14.1, the show chassis power <detail> operational mode command output displays power usage information for the new DC power supply module (PSM) and power distribution unit (PDU) that are added to provide power to the high-density FPC (FPC2-PTX-P1A) and other components in a PTX5000 Packet Transport Router. The output also displays power usage information for each PIC that is connected to the router. This command also displays power usage information for MX Series routers that have a MPC5EQ MPC installed.
Starting in Junos OS Release 18.4R1, on MX240 routers and EX9204 switches, the enhanced AC PEM in high-line power configuration supplies a power output of 2400 W. On Junos OS versions prior to 18.4R1, this PEM supplied only 2050 W of power.
Starting in Junos OS release 21.4R1, on SRX5400 routers the AC redundancy mode for high capacity high line PEMs is increased from 1+1 to 2+2 with a capacity of 4100W from earlier 2050W.

Note:

The MX204 routers do not support the show chassis power command.

Output Fields

Table 1 lists the output fields for the show chassis power command. Output fields are listed in the approximate order in which they appear.

Table 1: show chassis power Output Fields:
