Q1: What is the main difference between the modular Cisco C9200-48T-E and the fixed C9200L-48T-4G-E?
A: The C9200-48T-E is a fully modular, enterprise-grade switch. It includes Field-Replaceable Unit (FRU) redundant cooling fans, a hot-swappable uplink slot supporting 1G or 10G modules, 160 Gbps stacking bandwidth, and a larger MAC address table of 32,000 entries. In contrast, the C9200L series uses fixed fans, fixed uplinks, 80 Gbps stacking, and supports up to 16,000 MAC addresses.
Q2: Does the C9200-48T-E switch support Power over Ethernet (PoE)?
A: No. The "T" designation indicates a data-only switch designed for standard wired connectivity. It does not provide PoE power. For deployments requiring power delivery to IP cameras, VoIP phones, or wireless access points, the C9200-48P-E model is the appropriate choice.
Q3: What power supply comes standard with this switch?
A: Because it does not deliver PoE, the switch is highly energy-efficient and ships with a compact 125W AC primary power supply (PWR-C6-125WAC). A secondary 125W power supply can be added to provide 1+1 redundancy.
Q4: Which network uplink modules (NM) can I use with the C9200-48T-E?
A: This model supports the C9200-NM-4G module, offering four 1G SFP ports, and the C9200-NM-4X module, which provides four 1/10G SFP+ ports, enabling flexible uplink scalability.
Q5: Can I use 25G or 40G uplink modules on this model?
A: No. The 25G (C9200-NM-2Y) and 40G (C9200-NM-2Q) modules are only supported on Catalyst 9200 Multigigabit (PXG) models and are not compatible with this standard Gigabit switch.
Q6: What routing features are included in the Network Essentials license?
A: The Network Essentials license provides foundational routing capabilities suitable for branch and access layers, including static routing, RIP, EIGRP Stub, PIM Stub multicast, and OSPF limited to 1000 routes.
Q7: Can I build an SD-Access fabric with the C9200-48T-E?
A: No. The Network Essentials license does not support SD-Access or advanced segmentation technologies such as VRF and VXLAN. Upgrading to the Network Advantage license is required to enable full SD-Access functionality with Virtual Networks.
Q8: Are the cooling fans field-replaceable (FRU)?
A: Yes. As a modular enterprise-class switch, it includes FRU redundant cooling fans (FAN-T2=), allowing for hot-swappable replacement without interrupting network operations.
Q9: What is the actual switching capacity and performance?
A: The switch delivers a non-blocking switching capacity of 176 Gbps and a wire-speed forwarding rate of 130.95 Mpps, ensuring consistent performance across all 48 ports and uplinks.
Q10: Can I stack the C9200-48T-E with C9200L models?
A: No. Mixed stacking is not supported. Modular C9200 switches can only be stacked with other modular C9200 switches running the same license tier, using the StackWise-160 architecture with support for up to 8 switches.
Q11: Why is this specific SKU highly popular for IT resellers with physical stores?
A: It offers excellent inventory flexibility. Resellers can stock the base C9200-48T-E chassis and pair it with different uplink modules as needed, allowing them to quickly customize solutions and fulfill customer requirements without waiting for additional hardware.
Q12: What is the Mean Time Between Failures (MTBF) for this switch?
A: Due to the absence of PoE-related thermal load, the C9200-48T-E achieves a high MTBF of 571,440 hours, making it a dependable choice for continuous enterprise operation environments.
