FAQs for C9300-48U-A:
What is UPOE and how is it different from PoE+?
UPOE (Universal Power over Ethernet) provides up to 60W per port, nearly double that of standard PoE+, enabling support for more demanding devices like VDI terminals, compact switches, and video phones.
What kind of uplink modules are compatible with this switch?
It supports modular uplink slots with options for 4x1G, 4x10G, or 2x25G SFP/SFP+ modules depending on your network's needs.
Does this model support advanced routing protocols like OSPF and BGP?
Yes, with the Network Advantage license, it includes support for OSPF, EIGRP, BGP, and Policy-Based Routing.
Is this switch stackable with other Catalyst 9300 models?
Yes, it supports StackWise-480, allowing stacking with other 9300 switches to form a single logical switch.
Can I monitor traffic for security and analytics?
Absolutely. The switch supports Flexible NetFlow, Encrypted Traffic Analytics, and is fully integrated with Cisco DNA Center for deep visibility.
