Introduction

The C-NIM-8M is a LAN/WAN module with eight 2.5G BASE-T (Multigigabit) RJ-45 copper line ports. Its eight ports support 100M/1G/2.5G BASE-T connections also known as Multigigabit or “mGig” ports. The 2.5G mGig ports accommodate full-speed connections for new high-speed branch devices with 2.5G mGig uplinks, such as Wi-Fi 6 Wireless Access Points and Cellular Gateways. 10M (10BASE-T) is not supported on the C-NIM-8M. Four of its ports support up to 90W Cisco Universal Power over Ethernet Plus (Cisco UPOE®+; 802.3bt-compliant) while being backward compatible with PoE, PoE+, and UPOE. The capability for providing 90W UPOE+ can be used for powering even the most demanding devices, such as high-performance Wireless Access Points and Cellular Gateways directly from the host router. As with the other LAN/WAN modules in this family, this module’s two highest-numbered ports can be configured to operate in full Layer 3 mode with the added support of WAN MACsec.

The C-NIM-8M is supported on all Catalyst 8200 and 8300 Series platforms.
