Frequently Asked Questions (FAQ)

Q1: Is the C9300L-48T-4G-E PoE-capable?

A: No, this model (-48T) is data-only and does not support PoE/PoE+. For PoE+, use the C9300L-48P-4G-E model.

Q2: Can I stack this switch with other Catalyst 9300 models?

A: Yes, it stacks with other C9300L fixed-uplink models (e.g., C9300L-24T-4G-E) via StackWise-320. It is not compatible with C9300/C9300X modular models.

Q3: What software license is included?

A: It includes the Cisco Network Essentials license, providing core Layer 3 routing, security, QoS, and stacking features. For advanced features (e.g., BGP, MPLS), upgrade to Network Advantage.

Q4: Does it support cloud management?

A: Yes, it is fully compatible with Cisco DNA Center (on-prem) and Meraki Dashboard (cloud) for centralized monitoring, automation, and SD-Access integration.

Q5: What is the maximum number of switches in a stack?

A: Up to 8 C9300L switches can be stacked, providing up to 384 1G ports with 320 Gbps stacking bandwidth.

Q6: Are the power supplies and fans hot-swappable?

A: Yes, both the internal power supply and fan modules are hot-swappable for non-disruptive maintenance.

Q7: What is the warranty coverage?

A: The switch comes with a Cisco Limited Lifetime Warranty, including hardware replacement and software updates for the lifetime of the product.

Q8: Can I use 10G SFP+ modules in the uplink ports?
