Juniper ACX5448-D - ACX5448, ACX5448-D, and ACX5448-M Power System; AC Power Supply for ACX5400 Routers

AC Power Supply for ACX5400 Routers
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.
NOTE: Both the AFI and AFO PSMs look identical. Be sure to use the correct PSM for your
chassis product model (see Table 18 on page 54 for ACX5448 routers and Table 19 on page 55
for ACX5448-D and ACX5448-M routers).
CAUTION: Do not mix PSMs with different airflow in the same chassis. The system
raises an alarm when a PSM having a different airflow is inserted into the chassis.
CAUTION: Do not mix AC and DC PSMs in the same chassis.
