High-capacity second-generation AC PSM for SRX5800—Starting in Junos OS Release 21.4R1, SRX5800 supports the new high-capacity second-generation AC power supply module (PSM). This single or dual feed PSM provides a maximum output power of 5100 W. In single-feed mode, the PSM provides power at a reduced capacity (2550 W). In dual feed mode, the PSM provides power at full capacity (5100W). The PSM supports 1+1 redundancy.

High-voltage second-generation Universal PSM for SRX5800—Starting in Junos OS 21.4R1, the SRX5800 supports the new high-voltage second-generation universal power supply module (PSM). This single feed PSM provides a maximum output power of 5100W, and supports either AC or DC input. The PSM supports 1+1 redundancy.

The increased power supply capacity enables SRX5800 devices to support service cards like SPC3. show chassis power command displays PSM status, including state, input type, feed, capacity, output, and remaining power. show chassis environment pem command displays the power entry module (PEM) status for state, temperature, AC/DC input, and AC/DC output for the SRX5800 device.
