Extreme Networks Summit X150 Series Hardware Installation Manual page 311

Extreme Networks recommends that you install a power supply first in slot 1, but this is not required.
You can install power supplies into any of the slots in the EPS-C2 chassis. The installation sequence
does not affect the performance of the power supply units, but empty slots must be covered at all
times.
Warning
To prevent an electrical hazard, make sure that the AC power cord is not connected to the
power supply before you install the power supply in the power supply bay.
After the EPS-C2 has been installed in a rack, do the following to install a 750 W AC power supply in an
EPS-C2 chassis:
1 If necessary, grasp the two tabs on either side of the slot cover and pull gently to remove it from the
front of the EPS-C2 chassis.

2 Verify that the power supply is right side up (there is a sticker labeled "This Side Up").
3 Carefully slide the power supply all the way into the slot in the EPS-C2 chassis (see
