NOTE:
If you plug a power supply into a slot that has not previously contained a power supply, it
will self administer.
10 Reinstall the circuit packs and power supply.
11 If you are installing one G650 Media Gateway, replace the fan assembly and tighten the 7 screws
(all knurled screws must be tightened securely so that they cannot be loosened without the use of
a tool) and proceed to Installing the TN2312BP IPSI adapter
on page 76.
