WARNING
: Do not connect the power module to the external power source before installing it into the chassis.
Failure to observe this warning could result an electrical shock, even death.
Replacing the Power Supply Module
Note: The power supply can be hot swapped (i.e., swapped while the chassis is in operation) provided that it is
not connected to an active (switched ON) external power source. To replace the power module:
1. Make sure that the external power source is switched OFF.
2. Remove the chassis grounding lug if necessary.
3. Remove the ground wire connected to the power module.
4. Remove the Euro Block containing the power wires.
5. Remove and keep the two (2) 6-32 Philips head screws, securing the power module to the chassis.
6. Carefully pull the power module from the chassis.
7. Locate the new power module.
8. Install the Euro Block containing the two (2) power wires.
The IONPS-D-R1 has reverse polarity protection; if
incorrectly wired, the IONPS-D-R1 will not power up. Change the wiring connection polarity and continue.
9. Position the power module at the chassis slot, as shown in Figure 8 below.
10. Slide the power module completely into the chassis slot.
11. Insert the two screws to attach the power module to the chassis.
