• Make sure the AC power receptacles used to plug in the chassis are the grounding type. The
grounding conductors that connect to the receptacles should connect to protective earth ground at
the service equipment.
Four types of AC-input power supplies are available:
• 1000 W—Table 2-1 lists the AC-input power cord options, specifications, Cisco part numbers, and
shows the different styles of 1000 W AC-input power cord wall plugs that are available for North
America and international locations as well as the appliance coupler that is attached to the power
supply end of the power cord.
• 1300 W—Table 2-1 lists the AC-input power cord options, specifications, and Cisco product
numbers, and shows the different styles of 1300 W AC-input power cord wall plugs that are
available for North America or various international locations as well as the appliance coupler that
is attached to the power supply end of the power cord.
Note For North America, the power cord plug types and appliance couplers on the power suppl ies
are different for the 1000 W power supplies and the 1300 W power supplies; for other
countries, the plugs shown are the same for the 1000 W and 1300 W power supplies.
• 1400 W—Table 2-1 lists the AC-input power cord options, specifications, and Cisco product
numbers, and shows the different styles of 1400 W AC-input power cord wall plugs that are
available for North America or various international locations as well as the appliance coupler that
is attached to the power supply end of the power cord.
• 2800 W—Table 2-1 lists the AC-input power cord options, specifications, and Cisco part numbers,
and shows the different styles of 2800 W AC-input power cord wall plugs that are available for
North America and international locations as well as the appliance coupler that is attached to the
other end of the 2800 W power supply power cord.
• 4200 W—Table 2-1 lists the AC-input power cord options, specifications, and Cisco part numbers,
and shows the different styles of 4200 W AC-input power cord wall plugs that are available for
North America and international locations as well as the appliance coupler that is attached to the
other end of the 4200 W power supply power cord.
The cable part numbers use standard conventions as shown in this example: CAB-L620P-C19-US.
CAB-L means the cable will lock to the outlet. 620P means the cable is intended for a NEMA 220V 20
AMP circuit connection. C19 refers to the appliance side connector shape, rated for 20 Amps. US is the
country the cable is intended for use in.
