LL cable extends the length between any Aironet product and its antenna. With a loss of 6.7 decibels (dB) per 100 feet (30 meters [m]) for LL cable and 4.4 dB for the ULL cable, these cables provide installation flexibility without a significant sacrifice in range or performance. Cisco LL and ULL cables are not plenum rated
You provide power to a switch by using the AC internal power supply. The internal AC power supply is an autoranging unit that supports input voltages between 100 and 240 VAC. Use the supplied AC power cord to connect the AC power connector to an AC power outlet.
