Site Requirements
The typical power required for your Cisco 6160 system will depend on your configuration type. Use
Table 2-3
power required for the system.
Only a DC power source that is isolated from AC mains with reinforced insulation, and that complies
Warning
with the other safety extra-low voltage (SELV) requirements in UL1950, CSA 950 3rd Edition, EN 60950,
and IEC950, can be connected to a Cisco 6160 system. This requirement ensures that in a catastrophic
power source fault condition, hazardous voltages are not present on power terminals and connectors.
Table 2-3 Power Calculation for the Cisco 6160 System
Step Instructions
1
If you are using 8xIDSLs, multiply 5.5W by the total number of 8xIDSLs installed in
the chassis.
2
If you are using 8xG.SHDSLs, multiply 16.5W by the total number of 8xG.SHDSLs installed
in the chassis.
3
If you are using 8xDMTs, multiply 24W by the total number of 8xDMTs installed in
the chassis.
4
If you are using 4xSDSLs, multiply 9W by the total number of 4xSDSLs installed in
the chassis.
5
If you are using 4xflexis in G.lite mode, multiply 13W by the total number of 4xflexis (G.lite
mode) installed in the chassis.
6 If you are using 4xflexis in DMT mode, multiply 17.5W by the total number of 4xflexis (DMT
mode) installed in the chassis.
7 If you are using 4xflexis in CAP mode, multiply 13.5W by the total number of 4xflexis (CAP
mode) installed in the chassis.
8 Multiply 33.5W by the number of NI-2 cards installed in the chassis.
9 Enter 60W for the PEM. Add 6W if a second PEM is installed in the chassis.
10
Enter 104W for the fan tray.
11
Add lines 1 through 10. This is the typical power required for the Cisco 6160.
