Downgrading your Cisco CRS-3 Carrier Routing System 4-Slot Line Card Chassis Back to a Cisco CRS-1 Carrier
Make sure that the card is seated firmly in the Cisco CRS Fabric Card Chassis slot. One easy way
to verify physical installation is to see whether the front faceplate of the CRS-1 fabric card is even
with the fronts of the other cards installed in the card cage.
Check whether the ejector levers are latched and that the captive screws are fastened properly. If you
are uncertain, unlatch the levers, loosen the screws, and attempt to reseat the CRS-1 fabric card.
Examine the Cisco CRS Fabric Card Chassis alarm module to see if there are any active alarm
conditions. (See the section on the alarm module in Cisco CRS Carrier Routing System 4-Slot Line
Card Chassis System Description.)
Examine the Cisco CRS Fabric Card Chassis power shelves to see whether the chassis, as a whole,
is receiving power.
When the CRS-1 fabric card is properly installed, the Status LED turns green. If this LED is off,
verify that the CRS-1 fabric card is installed correctly.
If there is a failure during the board boot sequence, the two four-digit alphanumeric LED displays
indicate the current boot phase to assist you in debugging the board failure.
