Keep the shipping material. You must use the original shipping
material if you need to return the chassis to Allied Telesyn.

you carefully slide the line card into the slot. See Figure 16.
Avoid touching the components on the line card.

8. Slide the line card into the chassis until the faceplate is flush with the
front of the chassis.
9. Secure the line card to the chassis by using a Phillips screwdriver to
tighten the two installation screws on the line card faceplate.
After you have installed a line card, the WAIT/REMOVE LED on the
AT-8401 management card turns steady amber. The LED remains
amber for approximately 20 seconds. After the LED changes to
steady green, you can install another line card in the chassis. Do
not install a line card when the LED is amber.
