Connecting an External Ethernet Switch

Cisco C841M-4X-JSEC/K9 and C841M-4X-JAIS/K9 ISRs have four LAN ports and Cisco
C841M-8X-JAIS/K9 ISR has eight LAN ports. If you are using Cisco C841M-4X-JSEC/K9 or
C841M-4X-JAIS/K9 ISR, you can connect four PCs to the router. If you need to connect more than four
PCs, you can add Ethernet connections to the router by connecting an external Ethernet switch to the
Ethernet switch on the router. Similarly, if you are using Cisco C841M-8X-JAIS/K9 ISR, use an external
Ethernet switch to connect more than eight PCs.
To connect an external Ethernet switch to an Ethernet switch port on the router, perform these steps:
Connect one end of the Ethernet cable to an Ethernet switch port on the router, as shown in
Step 1
Note The connections remain the same for a 4 port module.
