The SM-ES3G-24-P is a Cisco Enhanced EtherSwitch service module with 24 10/100/1000 Ethernet ports, all of them gigabit-capable RJ-45 ports. It is single-wide, switches at Layer 2 and Layer 3, and supports Power over Ethernet.
Every port runs at 10, 100 or 1000 Mbps in full duplex, with autonegotiation under IEEE 802.3ab as the default, and an attached device can sit up to 100 meters (328 feet) away. The module has no SFP slot and no physical console; configuration happens in a console session through the host router. The default software image is IP Base, and each module links to the router fabric at 1 Gbps.
Unlike the SM-ES3-24-P, which has 23 10/100 ports and 1 gigabit port, this module has no Fast Ethernet-only ports. The router supplies -48 V to the module through its AC-PoE power supply and each port can be configured for PoE separately.
It works in Cisco 2911, 2921, 2951, 3925 and 3945 routers: one module in a 2911 or 2921, up to two in a 2951 or 3925, up to four in a 3945. The 2901 and 1941 do not support it. A router for it is the CISCO2911/K9 2911 router, and more modules are in Cisco switches.
