The AC power supply for the switch is available in 320 W, 600 W, and 930 W models
(see Figure 16 on page 30 and Figure 17 on page 30). 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.

DC Power Supplies
All the EX4200 switches that are powered by DC power supplies except the
EX4200-24F-S and EX4200-48T-S switches are shipped with one DC 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 DC power supply for the switch is available in a 190 W model, with dual input feeds
for power resiliency (see Figure 18 on page 31).
