Installing The Chassis Cover - Cisco CISCO1841 - 1841 Integrated Services Router Hardware Installation Manual

Installing the Chassis Cover

Installation of the equipment must comply with local and national electrical codes. Statement 1074
Warning
Caution Ensure that the inline power supply is not connected to the back of the router prior to installation of the
inline power supply card. Failure to do so may result in damage to the inline power supply card or to the
router.
When installing the inline power supply card, ensure that the card is installed in the proper direction.
Caution
Improper installation will result in damage to the inline power supply card. Installation of the inline
power supply card requires the installation of three metal standoffs, to which the card is then secured
using three screws. Be sure to use all three screws to ensure that the card is installed properly—if the
card is not installed in the correct direction, the three screw holes will not match up with the three metal
standoffs.
Find the metal standoff attachment locations on the system board, which are indicated by a star pattern
Step 1
surrounding each of the three holes in the system board.
Install the three metal standoffs into the system board in the metal standoff attachment locations
Step 2
(denoted by a star pattern around the holes). Use a 1/4-inch nut driver to tighten the standoffs.
Caution Make sure that the standoffs are straight when installed. Tighten them gently but firmly. The shoulder
of each standoff must be seated tightly against the system board.
Place the inline power supply card on top of the three metal standoffs, lining up the metal standoffs with

Step 4
standoffs. Carefully tighten the screws with a Phillips screwdriver.
After you install the inline power supply card in the router, install the router cover and connect the inline
power supply to the power connector on the back of the router.
