Juniper JPSU-850W-AC-AFO 850W Redundant Power Supply

The ACX5448 AC router operates at 650 W while the ACX5448-D and ACX5448-M AC routers need 850 W. The two power supply modules (PSMs) in ACX5400 routers are hot-removable and hot-insertable field-replaceable units (FRUs). The PSMs are installed in the router at the factory. You can replace the PSMs without powering off the router or disrupting the router function.
