Installing the ONS 15454 M6 Shelf

While changing the power modules from 15454-M6-DC20 to 15454-M6-DC and vice-versa, the ONS 15454

M6 shelf can temporarily work with both 15454-M6-DC and 15454-M6-DC20 power modules installed.

However, during regular operation, the shelf must either have the 15454-M6-DC or 15454-M6-DC20 power

module, but not both.

Insert the DC power module in Slot A or Slot B (or both) (see the following figure).

Figure 248: Installing the DC Power Modules

Plug the DC power module completely into the chassis.

Tighten the screw to a torque value of 4 in-lb (0.45 N-m) to lock the power module in the chassis (see the

following figure).
