TP-Link S4500-8GP vs Comnet CNGE8MS: Specification Comparison
Both the TP-Link S4500-8GP and the Comnet CNGE8MS are 8-port managed Gigabit switches targeting IP security and industrial network deployments. The S4500-8GP is a commercial-grade smart switch with PoE+ capability designed for structured cabling environments, while the CNGE8MS is a hardened managed switch built for harsh industrial conditions with DIN-Rail mounting and wide-range DC power input. Buyers weighing these two will primarily be trading off PoE power delivery and cloud management against industrial hardening, flexible fiber uplinks, and extended temperature tolerance.

Which switch delivers the right port mix, PoE budget, and fiber connectivity for this deployment?
The S4500-8GP provides 8 x RJ-45 Gigabit ports, of which 4 are PoE+ (802.3af/at) with a total PoE budget of 62W. It also includes 2 SFP slots for fiber uplinks. This makes it well-suited for powering and connecting IP cameras, access points, or VoIP phones in a single wiring closet. Power is delivered via an external 53.5 VDC / 1.31 A adapter.
The CNGE8MS offers 4 x RJ-45 copper ports and 4 x SFP combo ports (TX/FX), yielding half the copper density but significantly more fiber flexibility. It carries no PoE capability per its published specifications. Power input is dual DC 12–48 VDC, and typical power consumption is only 25W. The combo port design means up to 4 links can be fiber or copper depending on field conditions, a key advantage in runs exceeding standard copper limits or in electrically noisy environments.
Which switch is built to survive harsher physical and electrical operating conditions?
The S4500-8GP is rated for standard commercial installation. Its dimensions are 11.6 × 7.1 × 1.7 in and it supports wall or rack mounting. No operating temperature range is stated in the provided specifications, and it relies on a single external AC adapter — a single point of failure for power.
The CNGE8MS is explicitly hardened for industrial environments. Its specified operating temperature range is -40°C to +75°C and storage temperature -40°C to +85°C, with humidity tolerance of 5%–95% non-condensing. It supports DIN-Rail or wall mounting, making it compatible with industrial control panels and enclosures. Dual DC power inputs (12–48 VDC) provide redundant supply capability, significantly improving uptime in field or transportation deployments. Weight is under 3 lbs / 1.1 kg. For any outdoor enclosure, roadside cabinet, or manufacturing floor application, the CNGE8MS's environmental ratings are the decisive differentiator.
Which switch offers more capable network management, redundancy protocols, and standards compliance?
The S4500-8GP is managed at Layer 2+ via Web GUI and CLI (SNMP Trap/Inform, 802.1X, ACL, DoS Defense, EEE). It is part of TP-Link's Omada Pro ecosystem, which implies SDN-style controller management, though no specific controller compatibility is stated in the provided specifications. Switching capacity is 16 Gbps with 32 MB of onboard storage.
The CNGE8MS supports a broad IEEE standards set including 802.1D, 802.1p, 802.1Q, 802.1w, 802.1s, 802.1x, and 802.1AB (LLDP). Its ring redundancy options — C-Ring, Legacy Ring, and C-RSTP — are purpose-built for industrial network topologies requiring sub-50ms failover. It supports up to 4,096 VLANs and an 8,192-entry MAC table. Switching latency is specified at 7 μs. The CNGE8MS carries a lifetime warranty; no warranty term is stated for the S4500-8GP in the provided specifications.
Which should you choose: the S4500-8GP or the CNGE8MS?
Our take: The S4500-8GP is the stronger choice when the deployment requires PoE+ power delivery to cameras, APs, or phones in a climate-controlled commercial or enterprise environment with Omada ecosystem management. It provides a 62W PoE budget across 4 ports — a capability entirely absent from the CNGE8MS per its published specs — and integrates into TP-Link's Omada Pro controller framework. The CNGE8MS is the stronger choice for industrial, outdoor-enclosure, or transportation deployments: its -40°C to +75°C operating range against no stated operating temperature for the S4500-8GP, dual DC 12–48 VDC redundant power inputs versus a single external AC adapter, and hardware ring redundancy (C-Ring, C-RSTP) are specifications the S4500-8GP does not match. The CNGE8MS also carries a lifetime warranty versus no stated warranty for the S4500-8GP. Choose the S4500-8GP for PoE-powered commercial camera or Wi-Fi deployments; choose the CNGE8MS for hardened field or industrial network infrastructure.

Frequently Asked Questions
Which should you choose: the S4500-8GP or the CNGE8MS?
The S4500-8GP is the stronger choice when the deployment requires PoE+ power delivery to cameras, APs, or phones in a climate-controlled commercial or enterprise environment with Omada ecosystem management. It provides a 62W PoE budget across 4 ports — a capability entirely absent from the CNGE8MS per its published specs — and integrates into TP-Link's Omada Pro controller framework. The CNGE8MS is the stronger choice for industrial, outdoor-enclosure, or transportation deployments: its -40°C to +75°C operating range against no stated operating temperature for the S4500-8GP, dual DC 12–48 VDC redundant power inputs versus a single external AC adapter, and hardware ring redundancy (C-Ring, C-RSTP) are specifications the S4500-8GP does not match. The CNGE8MS also carries a lifetime warranty versus no stated warranty for the S4500-8GP. Choose the S4500-8GP for PoE-powered commercial camera or Wi-Fi deployments; choose the CNGE8MS for hardened field or industrial network infrastructure.
Can either switch power IP cameras directly without a separate PoE injector?
Yes — but only the S4500-8GP. It provides 4 x PoE+ (802.3af/at) ports with a combined 62W budget, which is sufficient to power several standard IP cameras. The CNGE8MS has no PoE capability listed in its published specifications, so cameras would require separate PoE injectors or PoE-capable midspans if paired with the CNGE8MS.
Which switch is better suited for an outdoor or industrial enclosure in extreme temperatures?
The CNGE8MS is the purpose-built choice for that application. It is rated for -40°C to +75°C operation, supports DIN-Rail mounting for panel installation, and accepts dual redundant DC inputs ranging 12–48 VDC. No operating temperature range is stated in the S4500-8GP's provided specifications, and it depends on a single external AC adapter, making it unsuitable for harsh or uncontrolled thermal environments.
Which switch provides better network redundancy for a ring topology?
The CNGE8MS provides explicit ring redundancy support via C-Ring, Legacy Ring, and C-RSTP protocols, which are industrial standards for fast failover in ring network architectures. The S4500-8GP's provided specifications list SNMP, 802.1X, ACL, and EEE management features but do not include proprietary ring redundancy protocols. For ring-topology resilience in a field or industrial deployment, the CNGE8MS is the documented choice.
