NOTE: EX4200-24PX and EX4200-48PX switches do not support the 930
W (EX-PWR-930-AC) or the 600 W (EX-PWR-600-AC) AC power supplies
that are used in the EX4200-48P and the EX4200-24P switch models.
EX4200-24PX and EX4200-48PX switches work only with the power supply
labeled EX-PWR2-930-AC. You can find the label on the top of the power
supply (see“Removing aPowerSupply froman EX4200 Switch” onpage 213).

AC Power Supplies
All the EX4200 switches that are powered by AC power supplies except the
EX4200-24F-S and EX4200-48T-S switches are shipped with one AC power supply
pre-installed in the rear panel of the switches. EX4200-24F-S and EX4200-48T-S
switches are not shipped with pre-installed power supplies; you must order them
separately.
The AC power supply for the switch is available in 320 W, 600 W, and 930 W models
(see Figure 17 on page 34 and Figure 18 on page 35). The exterior of the 600 W model is
identical in appearance to that of the 930 W model. The 320 W power supply is flush
with the chassis. The 600 W power supply and 930 W power supply extend out of the
chassis by 2.25 in. The power cord retainer clips extend out of the power supply by 3 in.
The number of ports on which PoE is enabled determines the minimum power
requirements of different switch models.
