Dc Power Supplies - Juniper EX4200 Hardware Manual

49
The AC power supply for the switch is available in 320 W, 600 W, and 930 W models (see
Figure 17 on page 49 and Figure 18 on page 49). 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.
