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.

To avoid electrical injury, follow instructions in Installing a Power Supply in an EX3200
Switch and Removing a Power Supply from an EX3200 Switch or
in an EX4200 Switch" on page 697
on page 695 carefully.
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 126 on page
or "Removing a Power Supply from an EX4200 Switch"
191).
