In North America, power cords for both 110 V and 220 V power input are shipped 
with the Switch 8800 chassis. The power cord required depends on the power 
output demands of the system. 

Table 24 lists the power cord type that is required for each power supply.

The North American 220 V power cord that is provided has a NEMA 6-20P 
20A/250VAC style plug.   The 220 VAC wall outlet needed for this plug is a NEMA 
6-20R 20A/250V style outlet.

The fan assembly consists of four to six individual fans and is located on the right 
side of the chassis. They operate on -48 V DC current. Each starter kit includes the 
appropriate fan assembly. Figure 8 illustrates the faceplate of the fan assembly for 
the 7-slot chassis.
