Cisco C9300LM-48T-4Y-E | Catalyst 9300L Mini 48-Port Gigabit Switch, 4x 25G SFP28

Q: Does the C9300LM-48T-4Y-E support Power over Ethernet?
A: No, this model is a data-only switch with 48 Gigabit Ethernet ports that do not support PoE, PoE+, or UPOE. For PoE requirements, consider the C9300LM-48U-4Y-E or C9300LM-48UX-4Y-E models.

Q: What is included with the Network Essentials license?
A: Network Essentials provides perpetual licensing for core Layer 2 and Layer 3 features including VLAN routing, static routing, OSPF, EIGRP, basic security features, and QoS. Optional DNA subscriptions can be added for advanced network automation and analytics via Cisco Catalyst Center.

Q: Can this switch be stacked with other Catalyst 9300 models?
A: Yes, the C9300LM-48T-4Y-E can be stacked with other Catalyst 9300L and 9300LM fixed uplink models using the optional StackWise-320 kit. However, it cannot be stacked with modular uplink models (C9300 or C9300X SKUs) or older Catalyst 3850/3650 switches.

Q: What is the StackWise-320 stacking option?
A: StackWise-320 is an optional stacking solution that provides 320 Gbps of stacking bandwidth for Catalyst 9300L and 9300LM models. Up to 8 switches can be configured as a single virtual switch with unified management and control planes, using dedicated stacking adapters and cables sold separately.

Q: What uplink speeds are supported on the 4x SFP28 ports?
A: The 4x SFP28 ports support 25 Gigabit Ethernet connectivity using compatible 25G SFP28 transceivers. These high-speed uplinks are ideal for connecting to distribution layer switches or data center infrastructure.
