CAUTION:
After you place the router on the slide rails from front of the rack, do not leave go of your hands
immediately because this might tip and damage the router.

mounting brackets on the router come into contact with the front rack posts.
The persons in front of the chassis push and a person in back of the chassis pulls the chassis by
holding two horizontal handles in the fan tray area (as shown in
Figure2-6 ).
CAUTION:
To avoid damaging the handles in the fan tray area, apply force only in the horizontal direction
rather than vertical direction when using the handles to pull the chassis.
