Common questions
Which DC model exhausts air at the port side?
The DC-AFI: air enters at the power-supply side and leaves at the port side. Its two JPSU-650W-DC-AFI supplies are 1+1 and hot-swappable.
How many members does the DC-AFI support?
It supports up to four switches managed together through EX4650 Virtual Chassis.
Does DC input change the base software license requirement?
No. DC power has no effect on licensing: the standard software runs without a license, and the add-on tiers are in Support & Licensing above.
