MX2010 DC Power Requirements
Table 66 on page 190 lists the FRU power requirements for SFBs, CB-REs, MPCs, and MICs. In addition,
Table 66 on page 190 lists the MPC power requirements with MICs and optics at various operating
temperatures.
Typical power represents power under certain temperatures and normal operating conditions.
For PDMs with 60 A feeds, we recommend that you select the 60 A @ –48 VDC switch for each input.
For PDMs with 80 A feeds, we recommend that you select the 80 A @ –48 VDC switch for each input.
NOTE: The 240 V China DC PDMs do not have a switch selection.
If you do not plan to provision as recommended above, you can use the information in
to calculate the power consumption for your hardware configuration.
