Adding or replacing the power supply
Figure 68. Sliding in the new power supply
1. Position the new power supply onto the alignment rails ( 1 ).
2. Slide the power supply into the module until it is flush with the back panel of the module.
3. Tighten the blue captive thumbscrews ( 2 ) with your îš³ngers to secure it to the module.
4. Attach the AC power cord to the new power supply ( 3 ) and plug the power cord into an outlet.
Installing a secondary power supply
1. Position the secondary power supply onto the alignment rails. Note the positions of the primary versus
the secondary power supplies - top versus middle bay.
2. Slide the power supply into the module until it is flush with the back panel of the module.
3. Tighten the blue captive thumbscrews with your îš³ngers to secure it to the module.
4. Attach the AC power cord to the new secondary power supply.
Verifying the power supply installation and operation
1. Verify that the new power supply is operating properly by checking the power supply LEDs.
• The white ( 2 in Figure 67 on page 130) LED is lit.
• The green ( 4 in Figure 67 on page 130) LED is unlit.
Note: If a second power supply is installed when the TS4300 is powered on (concurrent MES), the
green LED is lit.
With the Operator Panel or Management GUI, conîš³rm that the power supply is operating correctly. The
event that indicated that the power supply was faulty is cleared.
2. If the UID LEDs are still illuminated, deactivate them by using the Operator Panel or Management GUI.
