Cisco IE3300 Switch Buying Guide: Models and BOM Checklist

Cisco IE3300 selection starts with the cabinet role. Use IE-3300-8T2S for non-PoE industrial access with 1G SFP uplinks, IE-3300-8P2S for PoE/PoE+ access with 1G SFP uplinks, IE-3300-8T2X for non-PoE access with 10G SFP+ uplinks, and IE-3300-8U2X when the same cabinet needs UPOE and 10G SFP+ uplinks.

The IE3300 fits rugged DIN-rail access, modular port expansion, PoE endpoint support, and repeatable cabinet rollouts. It is not the correct substitute when the project requires PRP, HSR, DLR, Cisco TrustSec SGT, or SGACL; those requirements move the decision toward IE3400 or another supported industrial platform.

For model availability and quote requests, start from the Cisco IE3300 rugged switches category once the base model, expansion module, power supply, optics, and license tier are clear.

Cisco IE3300 Model Selection by Cabinet Requirement

The base switch should be chosen before accessories are added to the BOM. It defines the downlink type, uplink speed, default license suffix, and whether a PoE expansion path is valid.

Project requirement	Recommended IE3300 model group	Why it fits
Non-PoE industrial access with 1G fiber uplinks	IE-3300-8T2S-E/A	8 GE copper ports and 2 GE SFP uplinks for PLCs, HMIs, controllers, and industrial computers
PoE/PoE+ access with 1G fiber uplinks	IE-3300-8P2S-E/A	8 GE PoE/PoE+ copper ports for cameras, access points, phones, sensors, and badge readers
Non-PoE access with 10G uplinks	IE-3300-8T2X-E/A	8 GE copper ports and 2 10G SFP+ uplinks for cabinets feeding higher-speed aggregation
UPOE access with 10G uplinks	IE-3300-8U2X-E/A	8 4PPoE Type 3 copper ports and 2 10G SFP+ uplinks for higher-power endpoints and faster backhaul
More copper, PoE, or fiber ports later	Add IEM-3300 expansion modules	IE3300 systems can expand up to 26 ports depending on base switch and module choice
PRP, HSR, DLR, SGT, or SGACL	Move to IE3400-class evaluation	These requirements should not be handled as IE3300 substitutions

If the design only lists “Cisco IE3300” without a full PID, the quote is still incomplete. Procurement should request the exact base model, license suffix, expansion module, power supply, and optics before approving the order.

Cisco IE3300 Model Comparison: 8T2S vs 8P2S vs 8T2X vs 8U2X

Cisco IE3300 model comparison needs the full part number. A one-letter difference in the SKU can change PoE capability, uplink speed, and default license tier.

The -E suffix indicates Network Essentials as the default license. The -A suffix indicates Network Advantage as the default license. This suffix does not change the physical ports, PoE class, or uplink hardware.

Cisco IE3300 Part Numbers Explained: 8T, 8P, 8U, 2S, 2X, E and A

Cisco IE3300 part numbers combine the platform, port layout, uplink type, and default software tier. Keep the full model visible in the quote; a shorthand description such as “8-port IE3300 PoE switch” is not enough for BOM approval.

Part-number element	Meaning	Buying impact
IE-3300	Cisco Catalyst IE3300 rugged switch family	Confirms the industrial DIN-rail platform
8T	8 copper data ports	Non-PoE access endpoints
8P	8 PoE/PoE+ copper ports	Powered endpoints with 1G SFP uplinks
8U	8 UPOE / 4PPoE Type 3 copper ports	Higher-power endpoints with 10G SFP+ uplinks
2S	2 SFP uplinks	100/1000 SFP uplink planning
2X	2 SFP+ uplinks	1G/10G SFP+ uplink planning
-E	Network Essentials default license	Standard software tier
-A	Network Advantage default license	Higher software tier ordered with the hardware

Licensing can change software entitlement, but it cannot add PoE ports, UPOE capability, or 10G uplinks to a model that was not built with them. Decide the hardware fit before deciding the license tier.

Cisco IE3300 Selection Matrix for Industrial Cabinets

IE3300 deployments are often cabinet-level purchases, which makes model discipline important. A wrong base model can force a different power supply, a different optics plan, a different expansion module, or a failed acceptance check during commissioning.

Deployment scenario	Better IE3300 direction	What to verify before ordering
PLC, HMI, controller, or industrial PC cabinet	IE-3300-8T2S-E/A	Copper endpoint count, fiber uplink distance, industrial SFP temperature rating
Camera or access point cabinet with moderate load	IE-3300-8P2S-E/A	Endpoint watts, 48V/54V input, PoE reserve, expansion module plan
Machine vision or industrial wireless aggregation	IE-3300-8T2X-E/A	10G SFP+ optics, uplink path, cabinet power, software release
High-power endpoint cabinet	IE-3300-8U2X-E/A	Per-port power class, total 480W budget, power supply sizing, heat margin
Cabinet expected to grow beyond 10 ports	Base model plus IEM-3300 module	Cabinet width, module compatibility, PoE base requirement, spare module availability
Large spare-unit strategy	Standardize on the smallest valid model group	Confirm approved substitutes before a site outage occurs

For wider family placement, the Cisco industrial switch selection guide can help decide whether the project belongs in IE3300, IE3400, IE9300, or another industrial platform.

Cisco IE3300 PoE Budget: 240W, 360W and 480W Planning

PoE planning on the IE3300 is a power-system decision, not just a switch SKU decision. The IE-3300-8P2S model provides a 240W base PoE budget and 360W with module support. The IE-3300-8U2X provides up to 480W for higher-power endpoint designs.

The power supply must cover the switch and the powered-device load. Cisco identifies input-voltage requirements for PoE and PoE+ operation, including 48VDC for PoE and 54VDC for PoE+ or 4PPoE on relevant models. A PoE cabinet quote that omits the power supply should not be treated as a complete BOM.

Use this buying check:

PoE requirement	What to check
Basic PoE endpoints	Endpoint count, per-port wattage, 48VDC input, reserve margin
PoE+ cameras or APs	54VDC requirement, total watts, cable length, thermal conditions
UPOE / 4PPoE endpoint load	IE-3300-8U2X fit, 480W budget, power supply sizing
PoE expansion module	Confirm the base switch is a PoE base model and verify total system power
Redundant power design	Input feed plan, power supply wattage, cabinet wiring, maintenance access

For deeper BOM planning, review the Cisco IE3300 and IE3400 power supply module guide before finalizing the quote.

Cisco IE3300 10G Uplink Models: IE-3300-8T2X and IE-3300-8U2X

Choose IE-3300-8T2X or IE-3300-8U2X when the cabinet requires 10G SFP+ uplinks. The 8T2S and 8P2S models are 1G SFP uplink designs, so they should not be accepted for a project that specifies 10G backhaul.

10G uplinks make sense when the cabinet aggregates video, machine vision, wireless backhaul, multiple high-traffic endpoints, or a fiber run into a higher-speed distribution layer. They can also reduce early replacement risk when a site is standardizing on 10G aggregation while keeping rugged access switches at the edge.

Check optics carefully. Industrial SFP and SFP+ selection should account for fiber distance, connector type, operating temperature, and any derating conditions for non-industrial optics.

Cisco IE3300 Expansion Modules: IEM-3300 Port Growth Options

IE3300 expansion modules are useful when the cabinet needs more copper, fiber, PoE, or mixed ports after the base switch is selected. The base model still matters: PoE modules require a PoE-capable base switch, and the power budget must be validated before powered expansion is approved.

Expansion module	Adds	Buying note
IEM-3300-8T	8 GE copper ports	Standard copper expansion for non-PoE endpoints
IEM-3300-16T	16 GE copper ports	Higher-density copper expansion
IEM-3300-8S	8 GE SFP ports	Fiber expansion for cabinets with more optical runs
IEM-3300-6T2S	6 GE copper + 2 GE SFP	Mixed copper/fiber expansion
IEM-3300-14T2S	14 GE copper + 2 GE SFP	Higher-density mixed expansion
IEM-3300-8P	8 GE PoE/PoE+ copper ports	Requires PoE base planning and power budget check
IEM-3300-16P	16 GE PoE/PoE+ copper ports	Higher-density PoE expansion; power supply sizing is critical
IEM-3300-4MU	4 x 2.5GE 4PPoE copper ports	High-power and multigigabit expansion; confirm endpoint class and total PoE budget

Expansion also affects physical layout. Single-wide and double-wide modules change the installed width of the system, so cabinet space should be checked before the BOM is released.

Cisco IE3300 Network Essentials vs Network Advantage for Industrial Orders

For IE3300 procurement, Network Essentials and Network Advantage are software-tier and ordering decisions. Network Advantage includes the Network Essentials feature set, but the -A suffix does not change the physical ports or PoE hardware.

Choose Network Essentials for standard industrial access, Layer 2 switching, basic management, and typical access-layer security. Choose Network Advantage when the project standard requires the higher tier, when routing scale or advanced software features are part of the design, or when the customer specification names Network Advantage explicitly.

If the preferred -A hardware PID has longer lead time, procurement can evaluate the matching -E model plus the required Network Advantage license.

Cisco IE3300 Limitations: PRP, HSR, DLR, SGT and SGACL

The IE3300 is a strong fit for rugged access, modular growth, 10G uplink options, and PoE/UPOE cabinet designs. It is not a substitute for IE3400-class industrial redundancy and segmentation requirements.

Requirement in the specification	Better direction
PRP or HSR	Evaluate IE3400, IE3400H, IE9300, or another supported platform
DLR	Check IE3400-class support and software requirements
Cisco TrustSec, SGT, or SGACL	Validate the IE3400 path and expansion module compatibility
IEC 62439-3 zero-loss redundancy	Do not substitute IE3300 without engineering approval
Generic office access switching	Consider Catalyst campus access switches instead of an industrial IE model

For cross-platform decisions, use the Cisco IE3300 vs IE3400 comparison rather than forcing those requirements into an IE3300 model table.

Cisco IE3300 Model Comparison FAQ

Which Cisco IE3300 model should I buy for industrial access?

Choose IE-3300-8T2S for non-PoE access with 1G SFP uplinks, IE-3300-8P2S for PoE/PoE+ access with 1G SFP uplinks, IE-3300-8T2X for non-PoE access with 10G SFP+ uplinks, and IE-3300-8U2X for UPOE access with 10G SFP+ uplinks.

What is the difference between IE-3300-8T2S-E and IE-3300-8P2S-E?

IE-3300-8T2S-E is the non-PoE model with 8 GE copper ports and 2 GE SFP uplinks. IE-3300-8P2S-E adds PoE/PoE+ support on the 8 copper access ports while keeping the same 2 GE SFP uplink layout. Use 8P2S-E for powered endpoints such as cameras, wireless APs, phones, sensors, and access-control devices.

IE-3300-8P2S-E vs IE-3300-8U2X-E: what is the difference?

IE-3300-8P2S-E is the PoE/PoE+ model with 2 x 100/1000 SFP uplinks and a 240W base / 360W with module PoE budget. IE-3300-8U2X-E adds UPOE / 4PPoE Type 3 capability and 2 x 1G/10G SFP+ uplinks, with up to 480W PoE budget.

Does Cisco IE3300 support 10G SFP+ uplinks?

Yes, but only on the 10G uplink model groups. IE-3300-8T2X and IE-3300-8U2X provide 1G/10G SFP+ uplinks. IE-3300-8T2S and IE-3300-8P2S are 100/1000 SFP uplink models.

What is the Cisco IE3300 PoE budget?

IE-3300-8P2S provides 240W base PoE budget and 360W with module support. IE-3300-8U2X supports up to 480W. The final usable budget depends on the power supply, endpoint load, input voltage, and expansion module plan.

Can Cisco IE3300 expansion modules be used with IE3400?

IE3300 expansion modules can be physically used with IE3400 base switches, but Cisco notes that this combination can prevent support for advanced security features such as SGT and SGACL on the IE3400 base. For IE3400 TrustSec projects, validate module compatibility before ordering.

Is Network Advantage required for Cisco IE3300 switches?

Not always. Network Essentials is enough for many standard industrial access deployments. Select Network Advantage when the project specification, routing scale, software feature requirement, or customer standard requires it.
