Only Advanced Capability CompactFlash (CF) purchased from Cisco operates in Cisco 2900 series and Cisco 3900 series ISRs. Legacy CF can impact and several degrade performance in these routers. See the "Memory" section on page 1-21. When legacy CF is inserted, the following error message appears: WARNING: Unsupported compact flash detected. Use of this card during normal operation can impact and severely degrade performance of the system. Please use supported compact flash cards only. 3. Service module slots support legacy network modules when inserted with an adapter. See the router product page at Cisco.com for a list of supported modules.
