StarTech IESC1G50UP 5-Port Gigabit PoE+ Unmanaged Switch

Overview

The StarTech IESC1G50UP is a compact, unmanaged 5-port gigabit switch built for demanding edge deployments where space is tight and reliability is non-negotiable. Four of its five ports deliver up to 30W each via IEEE 802.3at (PoE+), with a 120W total power budget shared across those ports — enough to run four full-wattage cameras, access readers, or wireless APs simultaneously without throttling. The fifth port serves as a gigabit uplink to your core network. At just 4.1 × 3.2 × 1.3 inches and under 6 ounces, it fits a DIN rail inside a compact enclosure or mounts directly to a wall, making it the right pick when you need PoE at the edge rather than pulling long cable runs back to a central IDF closet. If you're sizing a distributed PoE switch architecture for a surveillance or access control deployment, the IESC1G50UP warrants a close look.

Key Features

• 30W PoE+ Per Port (IEEE 802.3at): Each of the four PoE ports delivers up to 30W — enough headroom for high-power PTZ cameras, dual-band APs, or intercoms. The switch is also backward-compatible with 802.3af devices at 15.4W, so legacy cameras don't require a separate injector or switch.
• 120W Total PoE Budget: The shared 120W budget means all four ports can operate at full 30W concurrently without any port being starved. For a four-camera run with PTZ or IR cameras drawing 20–25W each, this budget holds comfortably. Plan your power allocation before deployment to avoid mid-install surprises.
• 10/100/1000 Mbps Auto-Negotiation on All Ports: Full gigabit throughput on every port means 4K camera streams, high-bitrate encoders, or NVR traffic won't bottleneck at the edge switch. Unlike fast-ethernet edge switches, you won't need to revisit this hardware when you upgrade to higher-resolution cameras.
• Jumbo Frame Support (9K): 9K jumbo frames reduce CPU overhead on network devices handling large video payloads — relevant when streaming multi-stream H.265 or uncompressed video to an NVR or storage appliance. Most access-layer switches cap at 1.5K or 4K; 9K support here is a meaningful differentiator for high-throughput surveillance runs.
• -40°C to 75°C Operating Range: Industrial-rated thermal tolerance means this switch can live in an unheated exterior cabinet, a rooftop enclosure, or a parking garage in any climate. The -40°C lower bound is the same floor you'll find on enterprise-grade industrial gear — appropriate for cold-storage warehouses, outdoor kiosks, and northern-climate installs.
• IP-30 Rated Steel Housing: The steel enclosure provides protection against solid objects larger than 2.5mm — appropriate for a DIN-rail cabinet or wall-mounted enclosure. Not rated for direct water exposure; this switch belongs inside a NEMA-rated box if the install location sees moisture or washdown.
• 2kV Surge Protection: Built-in 2kV surge suppression on ports guards connected devices against transients from nearby lightning strikes or switching surges on the power bus. For outdoor camera runs where cable picks up induced voltage, this is a practical line of defense — though not a substitute for proper grounding and external surge arrestors on long runs.
• DIN Rail and Wall Mount: Dual mounting options let you integrate this switch inside an existing DIN-rail control cabinet alongside PLCs, power supplies, or access control panels — no separate enclosure needed in many cases. Wall-mount flexibility also works for back-of-rack or junction-box installs. Pairs well with a 24V DC or 48V DC power supply in the same cabinet.
• 328 ft (100m) Maximum Cable Distance: Standard Cat5e/Cat6 reach on all ports — plan camera-to-switch runs accordingly. Exceeding 100m requires a PoE extender or mid-span injector; this switch won't auto-negotiate beyond that distance.
• MTBF of 538,451 Hours: That's roughly 61 years of calculated mean time between failures — a figure that reflects the industrial-grade component selection. For a 24/7 surveillance edge node that won't see scheduled maintenance for years, this kind of reliability baseline matters.
• 48–56VDC Power Input: DC input (not AC) requires a suitable DIN-rail or wall-mount power supply at 48–56V. Confirm your cabinet power supply matches this range before ordering — a 12V or 24V DC source common in some access control panels will not work here.

Integration and Compatibility

The IESC1G50UP is unmanaged, which keeps configuration overhead to zero — plug in devices and the switch handles auto-negotiation, PoE detection, and frame forwarding without a CLI or web interface. That also means no VLAN segmentation, no port mirroring for IDS, and no QoS prioritization — if any of those are requirements, step up to a managed gigabit PoE switch. IEEE 802.3x flow control is supported, which helps prevent buffer overflow when a camera or NVR temporarily saturates the uplink. The switch is compatible with any 802.3af or 802.3at powered device; non-PoE devices (laptops, NVRs with their own power) work on all five ports without any configuration change. For installations using IP cameras from any major manufacturer — Axis, Hanwha, Hikvision, Dahua, Uniview — PoE class negotiation is automatic. Review your PoE switch selection guide to match switch power budget to your device mix before finalizing the design.

Frequently Asked Questions

Q: Can the IESC1G50UP be mounted on a DIN rail inside a control cabinet?

A: Yes. The IESC1G50UP supports both DIN rail and wall mounting. Its compact 4.1 × 3.2 × 1.3-inch form factor is designed to fit inside standard enclosures alongside other DIN-rail hardware such as power supplies and terminal blocks.

Q: What is the total PoE power budget, and can all four ports run at full wattage simultaneously?

A: The total PoE budget is 120W shared across the four PoE ports. Since each port supports up to 30W, all four can operate at full 30W concurrently — the math works out exactly at the budget ceiling. Any devices drawing less than 30W leave headroom in the shared budget.

Q: Does the IESC1G50UP support IEEE 802.3af devices, or only 802.3at?

A: It supports both. The switch complies with IEEE 802.3af (up to 15.4W per port) and IEEE 802.3at (up to 30W per port). Legacy 802.3af cameras and access readers will be detected and powered correctly without any manual configuration.

Q: What is the warranty on the IESC1G50UP?

A: StarTech provides a 2-year manufacturer warranty on the IESC1G50UP.

Q: What power supply voltage does the IESC1G50UP require?

A: The switch requires a DC input between 48V and 56V. It does not accept standard AC mains input directly — a compatible 48–56VDC power supply or DIN-rail power converter is required. Verify your cabinet power supply output matches this range before installation.

Q: Can the IESC1G50UP operate in outdoor or cold-climate enclosures?

A: Yes, within a suitable enclosure. The operating temperature range is -40°C to 75°C, which covers cold-storage facilities, unheated parking structures, and northern-climate outdoor cabinets. The switch itself is IP-30 rated (internal protection only) and must be housed inside a weatherproof NEMA-rated enclosure if the environment involves moisture or dust exposure.

The spec I keep coming back to on the IESC1G50UP is the -40°C operating floor combined with the 120W PoE budget in a package smaller than a paperback book. For edge nodes in unheated enclosures — think parking garage ticket kiosks, cold-storage camera runs, or outdoor access control cabinets — most compact unmanaged switches tap out well before -40°C, which forces an oversized heated enclosure just to protect the switch. This one doesn't require that compromise.

Technical Highlights:

• 30W PoE+ Per Port / 120W Budget: All four PoE ports can deliver full 30W simultaneously — no dynamic budget reallocation, no port priority tiers. You get exactly what the spec says, which matters when you're powering four PTZ cameras or high-draw wireless APs off a single edge node.
• 9K Jumbo Frame Support: Most unmanaged edge switches top out at 1.5K or skip jumbo frames entirely. At 9K, this switch won't be the bottleneck when high-bitrate camera streams or bulk NVR writes hit the uplink — important for 4K multi-stream deployments where frame fragmentation adds latency.
• MTBF of 538,451 Hours: That's a calculated 61-year mean time between failures. For an edge node that lives in a cabinet and gets inspected twice a year, that reliability figure gives you reasonable confidence it won't be the component that causes a 2 AM service call.

Deployment Considerations:

• The 48–56VDC input requirement is the most common installation stumbling block. Many integrators assume any PoE switch accepts AC or 12/24V DC. Confirm your DIN-rail power supply output is within this DC range before the cabinet is built — retrofitting a different PSU after the fact costs time.
• IP-30 is internal protection only — solid objects over 2.5mm, nothing more. Any install with moisture, condensation, or industrial dust needs a sealed NEMA 4 or NEMA 4X enclosure around the switch. Don't rely on IP-30 for anything beyond a clean indoor cabinet.

The IESC1G50UP is the right call for a DIN-rail edge node in a small-footprint outdoor or industrial cabinet: four camera drops at full PoE+ wattage, gigabit throughput, genuine cold-weather tolerance, and a steel housing that fits the same rail as your power supply and surge protection gear. It's not the answer if you need VLANs, port mirroring, or SNMP visibility — but for an unmanaged four-camera junction point, it's purpose-built for exactly that role.
