Power specifications
CAUTION:
To remove power to the 2109 Model M12, disconnect both power cables. (5)
The 2109 Model C36 with Model M12 supports F_port, FL_port, and E_port
connections and distributed name server (DNS). It is electro-magnetic compatibility
(EMC) compliant.
The power supplies are universal and capable of functioning worldwide without
using voltage jumpers or switches. They meet IEC 61000-4-5 surge voltage
requirements and are autoranging in terms of accommodating input voltages and
line frequencies. Each power supply has its own built-in fan for cooling, pushing the
air towards the port side of the chassis.
The power specifications listed in Table 13 are calculated for fully-loaded systems
with four power supplies. A fully-loaded system has eight 16-port cards, two CP
cards, and three blower assemblies.
Table 13 lists the power specifications for the 2109 Model C36 with Model M12.
