Cisco Systems MAS-7K, MAS-7507, CHAS-7507, CHAS-7K manual Moving Power Supplies

Moving System Components

Step 6 While keeping the carrier at a 90-degree orientation to the backplane, carefully slide the carrier into the slot until the back of the faceplate makes contact with the ejector levers. (See Figure 8b.)

Step 7 Using the thumb and forefinger of each hand, simultaneously push the top lever down and the bottom lever up 90 degrees to fully seat the board connectors in the backplane. (See Figure 8c.)

Caution Do not use unnecessary force when installing processor modules. Always guide the board carrier into the slot only until the carrier faceplate is flush against the ejector lever, then use the ejector levers to push the interface processor fully into the slot and seat it in the backplane properly.

Step 8 Use a screwdriver (Number 2 Phillips or 1/4-inch flat-blade) to tighten the captive installation screws on the top and bottom of the faceplate. (See Figure 8).

Step 9 Repeat Steps 1 through 8 for each remaining processor module, working from right to left. Before removing a processor module from the existing chassis, remove the blank board carrier from the corresponding slot in the replacement chassis. Try to replace interface processors in the same slot number you removed them from to avoid confusion when reconnecting cables and checking the installation.

Step 10 Proceed to the next section to move the power supplies.

Note Leave the blank board carriers installed in all unfilled interface processor slots.

Moving Power Supplies

You can insert the power supplies and connect the power cables, but do not turn on system power until you are ready to restart the system and check the installation. Always install the first power supply in the lower power supply bay and the second, if any, in the upper bay. Remember to tighten the captive installation screw on the top of each power supply. The screw prevents the supply from becoming dislodged from the power connections inside the chassis and also provides proper grounding for the system.

Follow these steps to move a power supply:

Step 1 If you have already removed all power supplies, proceed to Step 7.

Step 2 Ensure that the switch on each power supply is turned fully to OFF (O), then disconnect all power cords from the power sources.

Step 3 Disconnect the power cable from each power source.

Step 4 Disconnect the power cable from each power supply.

Step 5 Use a screwdriver to loosen the captive installation screw on the power supply in the lower bay.

Step 6 Grasp the power supply handle and pull the supply out of the bay. Place one hand underneath to support the bottom of the supply as you pull it out of the bay. (See Figure 10.) Immediately proceed to the following step to install the removed power supply in the replacement chassis.
