HP A6616 Installation Manual page 83

The device supports hot-swapping of FIPs.

If there is a great resistance when you push a FIP into a slot, first remove the blank panels at

both sides of the slot, then install the FIP, and finally install the removed blank panels to prevent
dust from entering the chassis.
Do not insert/remove a HIM/MIM into/from a FIP when the RUN LED on the FIP is blinking fast.

Otherwise, an abnormality may occur.
By default, the RUN LEDs of the FIPs will light up in the ascending order of slot numbers.

For a device configured with an RPE-X1 and a combination of FIPs including FIP-100, FIP-110,

FIP-200, and FIP-210, the application of FIP-110/FIP-200/FIP-210 is loaded faster than the
application of FIP-100, that is, the RUN LEDs of the FIP-110, FIP-200 and FIP-210 start to blink
long before the RUN LED of the FIP-100 does. Do not remove the FIP-100 at this moment.
For more information of the FIP LEDs, see "FIPs" in Chapter 1 "Router Overview."

Removing a FIP
Do not unplug a working FIP when its RUN LED is fast blinking. Doing so may cause

malfunction on the board.
Be sure to run the remove slot slot-number command before removing a FIP while the router

is operating.
If you have run this command but do not want to remove the FIP, use the undo remove slot

slot-number command to cancel the operation.
It is unnecessary to run the undo remove slot slot-number command after you remove a FIP

and insert it again.
The following describes how to remove a FIP-200. You can remove other FIPs in a similar way.
Step1 Face the front panel of the router.
Step2 Locate the FIP to be removed. The figures below illustrate how to remove the FIP from Slot 7.
Step3 Loosen the captive screws on the FIP counterclockwise with a Philips screwdriver until all
spring pressure is released.
