We ship the EX4400 switches with one power supply installed in the rear panel of the switches. You can
install up to two power supplies in the switch. You must order the second power supply and a power
source cord (part number: CBL-JNP-PWR-DSUB) separately. The power supply slots are numbered 0
and 1 and each slot has a power icon next to it. The power supplies support front-to-back or back-to-
front airow direcons. The power supplies are fully redundant, load-sharing, and hot-removable and
hot-insertable eld-replaceable units (FRUs) when the second power supply is installed and running: You
can remove and replace either one of them without powering o the switch or disrupng switch
funcons.
