Determining the minimum number of 8004DC power
supplies to install
When configuring an Ethernet Routing Switch 8600 system, you should consider
total power consumption to ensure proper system performance.
The total input power-consumption of the components (modules and fan trays)
must not exceed the output power rating of the 8004DC power supply (850W).
To determine the minimum number of power supplies to install for the Ethernet
Routing Switch 8600 system:
1 Add the total (3.3 V and 12 V) input power consumption (wattage) for all
components (modules and fan tray assemblies). See “Technical specifications
for the Ethernet Routing Switch 8600 Chassis” in Installing and Maintaining
the Ethernet Routing Switch 8600 Chassis.
2 Refer to the output power rating of the 8004DC power supply. For the
8004DC power supply specifications, See
Appendix A, “Technical
specifications for the DC Power Supply,” on page 57 .
