Questions & Answers
What is the Cisco C-SM-40P4M2X switch module?
The Cisco C-SM-40P4M2X is a 50-port Catalyst Layer 2 switch module, featuring 40 PoE/PoE+ ports, 4 multigigabit ports, 2 40 Gbps uplinks and a UADP ASIC for high performance.
Which chassis is the C-SM-40P4M2X compatible with?
The C-SM-40P4M2X module is compatible with Cisco Catalyst 9500 and 9600 series chassis that support modular Layer 2 switch modules.
What are the key features of the C-SM-40P4M2X?
Key features include 50 total ports (40 PoE/PoE+, 4 multigigabit, 2 40 Gbps uplinks), UADP ASIC, hardware-based security, wire-rate switching and low latency.
What performance does the UADP ASIC deliver?
Cisco’s UADP ASIC provides up to 1.44 Tbps switching capacity, 1.08 billion packets per second throughput and deterministic low-latency forwarding.
How do I install the C-SM-40P4M2X module?
To install, power down the compatible chassis, slide the module into the designated slot until it clicks, secure the captive screws and power the chassis back on.
Does the module support Power over Ethernet?
Yes, the C-SM-40P4M2X provides PoE and PoE+ on 40 ports with up to 30 W per port and a total PoE budget of 800 W.
Which network protocols are supported?
The module supports IEEE 802.1Q VLANs, STP/RSTP/MSTP, LACP, LLDP, IGMP snooping and DHCP snooping for Layer 2 network segmentation and security.
What management options are available?
Management options include Cisco IOS CLI, Cisco DNA Center for automation, SNMP, RMON, NetFlow and web-based GUI via the parent chassis.
How do I configure VLANs on this switch module?
Use the Cisco IOS CLI or DNA Center to define VLAN IDs, assign switch ports to access or trunk mode, and apply VLAN tagging policies.
Is the C-SM-40P4M2X stackable?
This module is not stackable by itself but leverages the parent chassis’s stacking or chassis fabric for seamless scalability.
What are the environmental specifications?
Operating temperature ranges from 0 °C to 40 °C, storage from –40 °C to 70 °C, with 5%–90% relative humidity (non-condensing).
How scalable is the C-SM-40P4M2X solution?
Scalability is achieved through multi-chassis stacking up to 8 units, supporting up to 400 PoE ports and 20 40 Gbps uplinks.
What security features does the UADP-based module offer?
Built-in hardware ACLs, MACsec encryption, DHCP snooping, IP source guard and dynamic ARP inspection deliver robust Layer 2 security.
What warranty and support options are available?
Cisco offers a limited lifetime warranty on the module and optional SMARTnet support for 24/7 hardware replacement and software updates.
