IE-1000-4P2S-LM Description
IE-1000-4P2S-LM is a Cisco Industrial Ethernet 1000 Series lightly managed switch for industrial edge cabinets that need compact Layer 2 access with powered device support. The SKU provides six total ports, including four 10/100BASE-T PoE/PoE+ downlinks and two 100/1000 Mb/s SFP uplinks, with a 120W default PoE budget from a 48 to 54VDC input. It fits DIN-rail installations where field devices such as cameras, sensors, or access equipment need local Fast Ethernet PoE connectivity and fiber uplinks back to the plant or building network.

Product Performance
Key Features
IE-1000-4P2S-LM is the Cisco IE1000 orderable model for four PoE/PoE+ Fast Ethernet downlinks with two Gigabit SFP uplinks, so it should not be treated as the eight-port PoE variant or a copper-uplink data model.
The two 100/1000 Mb/s SFP uplink slots let the access cabinet use fiber media while keeping the local powered edge on four Fast Ethernet copper ports.
Cisco assigns this model a 120W PoE budget and 48 to 54VDC input range, making external power-supply sizing part of the purchase decision rather than an afterthought.
The IE1000 family supports web-based management through Cisco Device Manager and features such as VLAN handling, QoS, IGMP snooping, DHCP snooping, SNMP v2/v3, and port security.
The hardware guide describes DC-A and DC-B power connectors and one alarm output relay for PoE models, which matters when the cabinet design needs secondary power and external alarm wiring.
Compared with IE-1000-8P2S-LM, this SKU keeps the SFP uplink architecture but halves the powered copper count and uses a 120W PoE budget instead of 180W.
Application Scenarios
IE-1000-4P2S-LM fits a compact industrial access box where up to four powered Fast Ethernet endpoints need local PoE/PoE+ and the uplink must leave the cabinet over SFP fiber.
Select this SKU when the site needs the IE1000 web-managed Layer 2 feature set for VLANs, QoS, IGMP snooping, SNMP monitoring, and port security without stepping into a larger managed industrial switch family.
The model suits cabinet builds where DIN-rail mounting, dual DC input connectors, an alarm relay, and documented extended temperature ranges are reviewed before staging.

- In an IE-1000-4P2S-LM vs IE-1000-8P2S-LM comparison, both models use two 100/1000 Mb/s SFP uplinks; the difference is four PoE/PoE+ downlinks with a 120W PoE budget versus eight PoE/PoE+ downlinks with a 180W PoE budget.
- The IE-1000-4P2S-LM vs IE-1000-4T1T-LM difference is PoE and uplink media: IE-1000-4P2S-LM uses 48 to 54VDC input with SFP uplinks, while IE-1000-4T1T-LM is a non-PoE copper-uplink model with 12 to 24VDC input.
- For buyers checking IE-1000-4P2S-LM vs IE-1000-6T2T-LM, the comparison should focus on powered-port requirement and uplink type because 6T2T has six non-PoE downlinks and two 10/100 copper uplinks.
- Which model to choose depends first on the confirmed endpoint power plan, then on whether the uplink must be SFP fiber or 10/100 copper.
Selection Guide
1. Choose four powered ports plus SFP
Choose IE-1000-4P2S-LM when the order needs four 10/100BASE-T PoE/PoE+ access ports and two 100/1000 Mb/s SFP uplinks in the IE1000 family.
2. Move up only for more PoE endpoints
Move to IE-1000-8P2S-LM when eight powered copper ports or the 180W PoE budget is required, because the 4P2S model is the smaller PoE/SFP option.
3. Select a data model for copper-only access
Select IE-1000-4T1T-LM or IE-1000-6T2T-LM only when the design does not need PoE or SFP uplinks and the 12 to 24VDC non-PoE input range matches the cabinet plan.
4. Verify power and fiber before approval
Verify the 48 to 54VDC source, total powered-device load, selected SFP modules, grounding, alarm wiring, and enclosure temperature plan because these items control whether the 4P2S PID fits the site.

Ordering Checklist
|
Checkpoint |
Confirm on the order |
Why it matters |
|---|---|---|
|
Model line |
IE-1000-4P2S-LM with 4 PoE/PoE+ FE ports and 2 GE SFP uplinks |
Keeps the bill of materials on the smaller PoE/SFP model rather than the 8P2S or copper-only IE1000 variants |
|
Endpoint count |
Four powered 10/100 ports cover the connected devices |
Avoids paying for the larger PoE model or discovering that the cabinet needed more powered ports |
|
Uplink handoff |
SFP fiber uplinks are required at the site |
Separates this order from 4T1T and 6T2T models that use copper uplink ports |
|
Power design |
48 to 54VDC input supports the 120W PoE budget and 72W to 140.4W with PoE load |
Helps prevent a wrong-voltage supply or an undersized industrial power source |
|
Optics plan |
SFP modules are selected from Cisco-supported options for the needed media and reach |
Reduces staging risk from an optic or fiber mismatch |
|
Cabinet readiness |
DIN rail, protective grounding, alarm relay wiring, and enclosure temperature limits are reviewed |
Confirms the switch can be installed in the intended industrial enclosure |
