1. Double-wide EHWICs can fit into slot 0 and 1, and into slot 2 and 3. EHWIC slots support HWIC, VIC, and WIC.
2. 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. Cisco 2921 supports only one service module in the left slot.
3. Only Advanced Capability CF purchased from Cisco operates in Cisco 2900 series and Cisco 3900 series ISRs. Legacy CF will not operate in these
routers. 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.
