Facility requirements The facility housing the Core Switch 2/64 and SAN Director 2/128 must meet the following requirements: • Power requirements: • Input power requirements: 200-240 VAC, 12A, 50-60 Hz • Recommended power connector: IEC 320, EN60320 C19-Angled, 16A/250VAC • Adequate supply circuit, line fusing, and wire size, as specified by the electrical rating on the chassis nameplate • An air flow of at least 350 cubic feet per minute, available in the immediate vicinity of the switch • The power specifications listed in Table 22 Power specifications The power subsystem is a redundant +48V DC power distribution system with a provision for up to four 1000-watt, 48V DC bulk power supplies. Bulk power supplies produce the intermediate distribution voltage in the distributed power system. The power specifications listed in Table 22 are calculated for fully loaded systems with two power supplies. A fully loaded system has eight 16-port cards, two CP cards, and three blower assemblies. WARNING! Make sure you disconnect both power cables when you want to remove all power from the Core Switch 2/64 or SAN Director 2/128. Table 22 Power specifications Specification Value Input voltage A fully loaded switch requires a maximum of 750 Volt-Amps. This results in a main current of 3.2 amps at 240 VAC line voltage or 3.6 amps at 208 VAC line voltage. The rated AC input range is 180 to 264 VAC. Supported power range Nominal: 200 to 240 VAC, single phase Input Frequency range 47-63 Hz 138 Technical specifications
