FAQs

Q: What uplink modules are compatible with the C9300-48S-M?
A: The switch supports field-replaceable network modules including C9300-NM-4G (4x 1G), C9300-NM-8X (8x 10G), C9300-NM-2Q (2x 40G), and C9300-NM-2Y-M (2x 25G SFP28). Uplink modules are sold separately and provide flexible connectivity options from 1G to 100G depending on your infrastructure requirements.

Q: Does the C9300-48S-M require a Meraki license?
A: Yes, this model requires either an Enterprise or Advanced Catalyst 9300-M cloud license to enable Dashboard management, firmware updates, and support. Licenses are available in 1, 3, 5, 7, or 10-year terms and must be purchased separately from the hardware.

Q: Can I stack multiple C9300-48S-M switches together?
A: Yes, StackWise-480 technology allows you to stack up to 8 switches with 480 Gbps of stacking bandwidth using STACK-T1 cables. This creates a single logical switch for simplified management and provides high-bandwidth interconnection between stack members.

Q: What Layer 3 routing protocols does this switch support?
A: The C9300-48S-M supports static routing, OSPFv2, and VRRP for warm-standby redundancy. Layer 3 routing capabilities enable the switch to function as a distribution layer device in campus networks with inter-VLAN routing and dynamic routing protocols.

Q: Is this switch suitable for connecting fiber uplinks from access layer switches?
A: Absolutely. With 48 Gigabit SFP ports, the C9300-48S-M is ideal for aggregating fiber connections from access switches, wireless access points, or other network devices in enterprise campus environments where fiber runs are already deployed.
