FAQs

Q: Does the C9300LM-48T-4Y-A support Power over Ethernet (PoE)?
A: No, this model is a data-only switch and does not support PoE, PoE+, or UPOE. For PoE requirements, consider the C9300LM-48U-4Y-A or C9300LM-48UX-4Y-A models which offer UPOE capabilities.

Q: What is the stacking capability of this switch?
A: The C9300LM-48T-4Y-A supports StackWise-320 technology, allowing up to 8 switches to be stacked with 320 Gbps of stacking bandwidth. This creates a single management and control plane for simplified administration and enhanced resilience.

Q: What is included with the Network Advantage license?
A: The Network Advantage license provides advanced Layer 3 routing protocols (OSPF, EIGRP, BGP), enhanced security features (MACsec, TrustSec, 802.1x), policy-based routing, Quality of Service (QoS), and support for Cisco DNA Center automation and analytics capabilities.

Q: Is this switch compatible with existing Catalyst 9300 stacks?
A: Yes, the C9300LM-48T-4Y-A can be stacked with other Catalyst 9300L and 9300LM models using StackWise-320 cables. However, note that C9300LM models use different power supplies (PWR-C6 series) compared to standard C9300 and C9300L models.

Q: What are the primary use cases for this switch?
A: This switch is ideal for enterprise campus access layer deployments, branch office networks, and environments requiring high-speed gigabit connectivity with 25G uplinks for core or aggregation layer connections. The compact form factor makes it suitable for space-constrained installations.
