Installing the Alpine 3808 and the Alpine 3804 AC Power Supply
Extreme Networks Consolidated Hardware Guide 143
page 52. For more information about grounding the chassis, see “Grounding the Alpine 3800 Series
Chassis” on page 138.
You need the following tools and equipment to install the Alpine 3808 and the Alpine 3804 AC power
supplies:
• ESD-preventive wrist strap
• # 2 Phillips screwdriver
• AC power supply
To install the Alpine 3808 and the Alpine 3804 AC power supplies:
1 Attach the ESD strap that is provided to your wrist and connect the metal end to the ground
receptacle that is located on the top-right corner of the switch front panel.
2 If there is a blank faceplate covering the power supply bay, remove it and save it for future use.
3 Ensure that the power supply is oriented correctly for either the Alpine 3808 or Alpine 3804 using
the text on the front of the power supply, that the safety latch is in the “remove” position, and that
the ejector/injector lever is open, as shown in Figure 63 and Figure 64.
CAUTION
When you insert a power supply, use one hand to support the power supply from the bottom and the
other hand to hold the central handle on the front of the power supply. Do not use just the
ejector/injector lever to insert a power supply.
4 Use the central handle to guide the power supply into the power supply bay while supporting the
supply from the bottom with your other hand.
