Cisco IE-3400-8T2S-E Catalyst IE3400 Rugged Switch

IE-3400-8T2S-E: Cisco Catalyst IE3400 modular industrial switch with Network Essentials

The IE-3400-8T2S-E is the non-PoE base of the Cisco Catalyst IE3400 Rugged Series, a modular Gigabit switch with eight copper downlinks and two SFP uplinks. Seven Star LLC supplies IE-3400-8T2S-E in Oman and the GCC as an independent supplier based in Muscat, not affiliated with the manufacturer.

The IE3400 is the Advanced Modular sibling of the IE3300. Its data plane adds features aimed at utility and automation networks: Parallel Redundancy Protocol (PRP) on selected ports, High-Availability Seamless Redundancy in SAN mode, Device Level Ring, an HSR-PRP dual RedBox mode, and security group tagging with SGACL. The -E suffix gives the Network Essentials software license.

Decoding the part number IE-3400-8T2S-E

The IE-3400-8T2S-E reads as a chain of port counts followed by a license letter. The table decodes each element against the hardware configuration table of the series datasheet.

IE-3400-8T2S-E technical specifications

How the IE-3400-8T2S-E behaves in the network

PRP gives zero-recovery-time redundancy by sending every frame over two independent LANs, which is what substation automation designs use for protection traffic. On the IE3400 base the datasheet limits PRP to the first four Gigabit ports (Gig1/1 to Gig1/4) and a single instance, so the port plan must put the PRP connections there.

The same switch also supports the ring protocols of the IE3300 (REP and MRP) and can run IEEE 1588 PTPv2 with the power profile, which together make it suitable for time-critical utility applications. Jumbo frames are limited to 2000 bytes when ERSPAN, DLR, PRP, HSR or SGT is in use, a detail to check against traffic design.

Where IE-3400-8T2S-E fits: compatible and related parts

The IE-3400-8T2S-E accepts IEM-3400 modules (IEM-3400-8T=, IEM-3400-8S=) and IEM-3300 modules, with the caveat that IEM-3300 modules on an IE3400 base prevent SGT and SGACL. The PoE variants are IE-3400-8P2S-E and IE-3400-8P2S-A, and the Network Advantage version of this unit is the IE-3400-8T2S-A.

Selection and ordering checklist for IE-3400-8T2S-E

• Decide whether PRP or HSR is required; if so, the IE3400 rather than the IE3300 is the correct platform.
• Plan PRP connections on ports Gig1/1 to Gig1/4 only.
• Confirm the license: -E for Layer 2 and static routing; -A for dynamic routing, MACsec-256 and SGT.
• Choose IEM-3400 modules if TrustSec is planned.
• Check jumbo frame needs against the 2000-byte limit in redundancy modes.

Installation, commissioning and maintenance

Mount the IE-3400-8T2S-E on a standard DIN rail inside a cabinet. The platform is a convection-cooled design, so the cabinet air movement and the ambient limit you design to decide which temperature band of the datasheet applies; the quoted -40 to +75 °C band needs at least 200 LFM of airflow across the unit, while a sealed enclosure is rated to +60 °C. A DIN rail supply sized for 36 W plus modules is enough for the non-PoE base.

For redundancy designs, document which ports carry PRP, which carry rings, and which are ordinary access ports, and label them in the cabinet.

During commissioning, use the WebUI or the console to set the management address, confirm the ring protocol you intend to use (REP or MRP) and check the alarm contacts against the plant annunciator. Keep a copy of the running configuration on the optional SD card, because the SwapDrive feature lets a replacement switch of the same type come up with the stored configuration without a networking specialist on site. For routine care, review the syslog for link flaps, read the optical power on the fiber ports and keep the DC feeds free of ripple.

Typical applications in Oman and the GCC

The IE-3400-8T2S-E belongs in electrical substations and power plant control networks in the GCC where protection and automation traffic needs bumpless redundancy, and in utility-style networks at gas processing plants. The fanless body and wide temperature band suit unconditioned kiosks.

It is also used as the IE3400 starting point for sites that expect to add modules and TrustSec later. The non-PoE base keeps power draw to 36 W.
