Optional hot-swappable redundant second 1100WAC PSU expands total PoE budget up to 1590W; StackPower+ enables cross-stack power resource sharing across stacked units to allocate full 90W UPOE+ to demanding endpoints
• Single rear modular uplink expansion slot compatible with official C9300X dedicated network modules: C9300X-NM-8X (8×10G SFP+), C9300X-NM-4Y (4×25G SFP28), C9300X-NM-2Q (2×40G QSFP+), C9300X-NM-1C (1×100G QSFP28), flexible uplink bandwidth ranging from 1Gbps to 100Gbps

Core Platform Hardware Performance

• Standalone switching fabric capacity: 880 Gbps; aggregated stacking throughput via StackWise-1T up to 1880 Gbps
• Wire-rate standalone IPv4/IPv6 forwarding rate: 654.76 Mpps; max stacked aggregate forwarding throughput:1398.8 Mpps
• Stacking Architecture: Cisco StackWise-1T with 1000Gbps per-stack backplane bandwidth; maximum 8 identical C9300X-series switches can be stacked into one logical switching entity, supporting NSF/SSO sub-50ms non-stop forwarding failover protectionCisco
• Core system hardware: Quad-core x86 processor, 16GB DRAM +16GB onboard flash storage, three variable-speed hot-swappable cooling fans; embedded onboard Catalyst 9800 wireless controller supports centralized management of up to 200 enterprise Cisco wireless access pointsCisco
• Forwarding table scale:
  MAC address table:96,000 entries; IPv4 route table:96,000 entries; IPv6 route table:48,000 entries; Multicast route table:24,000 entries; TCAM ACL/QoS table:24,000 entries; Jumbo frame support up to 9198 Bytes; 48MB deep packet buffer for bursty multicast & high-concurrency user traffic
