Step 6 Check the card LEDs to verify that the card is working properly. For information about feature card 
LEDs, see Chapter 7, “Troubleshooting.”
System Processing Engine Firmware
System processing engine (SPE) firmware is automatically downloaded to a universal port or dial-only 
feature card from the Cisco IOS image when you boot the system for the first time, or when you insert 
a universal port or dial-only feature card while the system is operating. When you insert feature cards 
while the system is operating, the Cisco IOS image recognizes the cards and downloads the required 
firmware to the cards.
For more information on universal port and dial-only feature card firmware and upgrade options, see the 
Cisco AS5350XM and Cisco AS5400XM Universal Gateways Software Configuration Guide.
