12 Cisco 12012 Gigabit Switch Router Switch Fabric Cards Replacement Instructions
Checking the Installation
Checking the Installation
Complete the following steps to verify that the new clock and scheduler card or switch fabric card
is working properly:
Step 1 Check the following components to make sure that they are secure:
• The cards in the lower card cage are fully seated in their slots and the card ejector
levers are retracted and latched in the card carriers.
• The air deflector in the lower card cage is down, resting on its stops.
• The air filter tray is up, flush with the front of the card cage assembly, and the two
captive screws are tightened.
Step 2 Observe the five pairs switch fabric status LEDs on the alarm card (rightmost slot in the
upper card cage):
• The green enabled LED should be on for all installed clock and scheduler cards and
switch fabric cards. If the LED is off, either the lower card cage slot is empty or the
card in that slot has not been installed correctly. Try reseating the card in the backplane
connector.
• The red fail LED should be off for all installed cards in the lower card cage. If the LED
is on, a fault has been detected in the card installed in that slot. The card might not be
installed completely or could have an internal fault. Try reseating the card in its slot.
If that does not resolve the problem, contact your service representative for assistance.
FCC Class A Compliance
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference, in which
case users will be required to correct the interference at their own expense.
You can determine whether your equipment is causing interference by turning it off. If the
interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices.
If the equipment causes interference to radio or television reception, try to correct the interference
by using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That
is, make certain the equipment and the television or radio are on circuits controlled by different
circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval
and negate your authority to operate the product.
