Alpine™Power Supply Installation
Note
Alpine 3800 series switch power supplies are hot-swappable. You can add a second power supply
without powering off the chassis. If you have two power supplies installed, you can remove one of
them without powering off the chassis.
The power supplies on the Alpine 3804 switch are inserted into the lower rear of the chassis. The power
supplies on the Alpine 3808 switch are inserted into the front of the chassis.
Caution: Service to Alpine power supplies should be performed by trained service personnel
only. Before installing or removing any components of the system, or before carrying out any
maintenance procedures, you must read the safety information provided in Appendix A of
the
Alpine Hardware Installation Guide .
REMOVING AND REPLACING AN ALPINE 3804 POWER SUPPLY
To remove and replace a power supply on the Alpine 3804 switch, follow these steps:
1Locate the power supply on the lower rear of the chassis.
2Remove the AC power cord from the power supply.
3Slide the locking latch on the power supply so that it covers the AC power connector.
4Unscrew the screw on the ejector/injector lever using a #2 Phillips-head screwdriver.
5Pull the ejector/injector lever towards you while holding on to the central handle to steady the
power supply.
6Supporting it with one hand, slide the power supply out of the chassis.

Caution: Ensure the latch covers the AC power connector. The power supply cannot be removed
or installed unless the connector is covered.
7Make sure that the replacement power supply is right-side up as described by the text on the front of
the power supply, that the ejector/injector lever is open, and that the safety latch covers the AC
power connector.
8Use the centrally mounted handle to slide the power supply into the bay. Use the ejector/injector
lever to engage/disengage the power supply connectors during the last inch of insertion into the
chassis.
Caution: Do not slam the power supply into the backplane. This will cause damage and possibly
require the return of the chassis.
9Secure the power supply by tightening the screw on the ejector/injector lever using a #2
Phillips-head screwdriver.
10 Slide the locking latch covering the AC power connector to the left until it locks into the chassis.
