Replacing the Chassis Interface (CI) Board in the Cisco 7500 Series Chassis 29
Checking the CI Installation
Step 2
Place your fingers around the edges of the CI (as shown in Figure 19); carefully guide it
over the chassis panel (shown cut away in Figure 19) and push it straight in toward the
backplane until the CI connector is fully seated in the backplane socket and the standoff
screw holes are aligned with the standoffs. It might be necessary to gently rock the
connectors into place.
Step 3
Install the four Phillips screws that secure the CI and gently tighten them. Do not
overtighten these screws.
Step 4
To replace the backplane maintenance cover, follow Steps 4 and 5 in the section
“Removing and Replacing the Backplane Maintenance Cover” on page 25.
Step 5
To replace the chassis cover panels, refer to Step 3 in the section Removing and Replacing
the Chassis Cover Panels” on page 22.
Step 6
Reconnect the power supplies and power sources and prepare to power up the system.
This completes the CI replacement procedure in the Cisco 7513.
Checking the CI Installation
After you reassemble the chassis and replace all covers, perform the following steps to verify that
the new CI is installed correctly and functioning properly. These steps will also help you verify that
all the components you removed or disconnected as part of this replacement procedure are returned
to their previous state when all router components (except the failed CI) were operating properly.
Step 1
Turn the system power switch back ON. The DC OK LED should go on immediately. If it
does, proceed to the next step. If it does not, do the following:
•
First ensure that the power switch is completely in the ON (|) position.
•
Check the power cable; ensure that the cord is fully inserted in the power supply
receptacle and that it is properly connected to the power source.
•
If the LED still remains off and you are checking the CI installation on a Cisco 7505,
turn the power switch OFF, remove the chassis cover and verify that the fan tray is
installed correctly.
Ensure that the edge connector is fully seated in the backplane receptacle and that the
fan tray is pushed all the way back into the chassis so that the M4 pan-head screw is
tightened and holding the tab flush against the chassis frame. If not, refer to the section
“Removing and Replacing the Fan Tray” on page 7, to install the fan tray correctly; then
repeat step 1.
•
If the LED still remains off, and you are checking the CI installation on a Cisco 7505,
turn the power switch back OFF; then remove the chassis cover and power harness
cover. Verify that the power harness connector is fully seated in the backplane
receptacle. Replace the power harness cover and chassis cover; then repeat step 1.
Note
If the LED still remains OFF, and you are checking the CI installation for a Cisco 7507 or
Cisco 7513, contact a service representative for further instructions. (For the TAC phone number and
e-mail address, refer to the note following the section “Cisco Connection Online” on page 39.)
