Powering Up the Switch Platform
Note: Make sure that the power cords are compatible with your outlets. Power cords for differ-
ent countries can be ordered from Mellanox.
1. Plug in the power cord to the PSU.
2. Clamp the power cord to the chassis.
Each PSU has a clamp next to it, for supporting the power cord. Use this clamp to remove possible
strain on the PSU. The length of power cord between the clamp and the PSU must be less than 6”
(15cm). See Figure 19,“Electrical Cable Clamp”.
3. Plug the other end of the power cord into a grounded outlet.
4. Repeat steps 1 to 3 for the remaining power supply units.
Note: A fully loaded MTS3610 switch system can draw 5.2 kW of power. Make sure that the
outlets and circuits will not be overloaded. Spread out the load over at least two or three circuits.
Figure 19: Electrical Cable Clamp
The switch system requires at least six PSUs to operate a fully populated platform. The seventh
and eighth PSUs provide a failover protection mechanism such that the system will continue oper-
ating if one or more of the PSUs fail. Connecting the PSUs to different AC lines provides AC
failover protection.
A system should continue to run and allow a hotswap of a defective PSU even if it has only six
PSUs.
When only six PSUs are installed, five of them must be installed vertically along the right side of
the chassis.
The power system will divide the current consumption by the number of working PSUs. Should
one of the PSUs fail, the total current consumption will then be divided by the remaining working
PSUs. When the failed PSU is hot swapped the new PSU will ramp up and pass its share of cur-
rent, so that the total current is always divided by the number of working PSUs.
