1.11 Apply and Check Power
1. Ensure the customer power supply is OFF.
2. Ensure that the ATI 9400 shelf circuit breakers are OFF (0).
3. Turn the customer power supply ON. Power is now being applied to the terminal block but not to the shelf
components.
4. With the power/grounding plastic cover still removed, check for voltage at the terminal block using a voltme-
ter. With the shelf operating a nominal voltage of -48VDC, the reading should be between -40 to -57.6 VDC.
If the voltage is outside this range, check the customer-supplied power.
5. Put the plastic cover back on.
6. Turn the ATI 9400 circuit breakers ON (-).
7. The fans will start to operate.
Note: If the fans do not operate, ensure the FM7 is installed as part of the chassis. If the FM7 is
installed, contact your ATI representative.
The 9400 shelf fans will start operation at a very high speed. Fan speed is self-regulating and will automatically
adjust as necessary. After a short period of time, fan speed will automatically reduce. Insure that the fans start
when the 9400 shelf circuit breakers are turned ON(-) and that they reduce speed within a few minutes.
Note: If the fans do not reduce speed after a few minutes, turn the 9400 shelf circuit breakers OFF (0)
and contact your ATI representative.
8. Turn the shelf circuit breakers OFF (0).
9. The shelf is now ready for the remainder of the cards to be inserted
1.12 Install the Control Module
Note: Do not attempt to install system cards without observing correct antistatic procedures. Failure
to do so may damage cards.
1. Take the card from its antistatic container. (Set aside the Special Instructions for Ferrite instructions and
the ferrite for the Ethernet cable. Refer to Section 1.18.3.)
2. Hold the card securely with the lock-latch and label on the inside of the chassis as illustrated in Figure 1-13.
Note: This example is for the CFC24, but it can be applied to any CM supported by the 9400
system.
