Cisco IE-3300-8T2S-E Catalyst IE3300 10-Port Rugged Switch

IE-3300-8T2S-E: Cisco Catalyst IE3300 compact 10-port industrial switch, Network Essentials

The IE-3300-8T2S-E is the entry base unit of the Cisco Catalyst IE3300 Rugged Series: ten Gigabit ports in a DIN rail housing that is 3.6 in wide, with eight copper downlinks, two SFP uplinks and no Power over Ethernet. Seven Star LLC supplies IE-3300-8T2S-E in Oman and the GCC as an independent supplier based in Muscat, not affiliated with the manufacturer, and this page explains what the part number means, which numbers matter and what to confirm before ordering.

It is the right base when the downstream devices carry their own power, such as PLCs, remote I/O racks, drives and HMI panels, and the aim is a clean Gigabit access ring with fiber back to the control room. The suffix -E means the unit ships with the Network Essentials software, which covers Layer 2 switching, static routing and the industrial protocol set; the -A sibling adds the Network Advantage routing features.

Decoding the part number IE-3300-8T2S-E

The IE-3300-8T2S-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-3300-8T2S-E technical specifications

How the IE-3300-8T2S-E behaves in the network

The IE-3300-8T2S-E is a store-and-forward Layer 2 switch with line-rate forwarding on all ports and all packet sizes, eight egress queues and a 16K MAC table. In a ring, the two SFP ports normally carry the ring links, and the Resilient Ethernet Protocol (REP) or the PROFINET Media Redundancy Protocol (MRP) restores the path after a fiber break. Both are listed for the Network Essentials feature set.

Because this variant has no PoE load, its power draw is the lowest of the series: 23 W for the base at 12 V, with a maximum input current of 3.8 A. That makes it comfortable on a shared 24 VDC control bus with a modest supply, and the dual DC inputs allow a second feed from an independent source. The two alarm inputs and one output relay let the switch report a lost feed or a failed link to the plant monitoring system.

Where IE-3300-8T2S-E fits: compatible and related parts

The IE-3300-8T2S-E accepts the IEM-3300 expansion modules on its side, for example IEM-3300-8T= or IEM-3300-16T= for more copper ports, IEM-3300-8S= for fiber and IEM-3300-6T2S= or IEM-3300-14T2S= for a mix. Modules that carry PoE only work with a PoE base, so IEM-3300-8P= and IEM-3300-16P= belong with the IE-3300-8P2S-E instead. The IE-3300-8T2S-A is the same hardware with Network Advantage, and the IE-3300-8T2X-E is the 10G-uplink counterpart.

Selection and ordering checklist for IE-3300-8T2S-E

• Decide the software tier first: -E for Layer 2 and static routing, -A if OSPF, BGP, PIM or MACsec-256 are in the design.
• Confirm that no connected device needs PoE; if one does, move to the IE-3300-8P2S-E.
• Check the uplink speed. Two SFP ports are 100/1000 only; a 10G backbone needs the IE-3300-8T2X-E.
• Select SFPs by distance and temperature class; industrial-rated optics keep the full temperature range, while commercial optics force a derating.
• Size the DIN rail supply for the base plus any modules, using the module consumption figures in the datasheet.

Installation, commissioning and maintenance

Mount the IE-3300-8T2S-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 the 23 W base plus modules, or a DC bus within 9.6 to 60 VDC, can power it.

Because the unit is non-PoE, wiring is limited to the DC feed, the alarm connector and the data cables, so the cabinet layout is simple. If you plan to add a module later, leave about 2 in of DIN rail to the side of the switch for a single-wide module or 3 in for a double-wide one.

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

A common use of the IE-3300-8T2S-E in the Gulf is the field access ring for a gas gathering station or a wellhead pad, where eight copper ports serve remote terminal units, flow computers and a local HMI and the two fiber uplinks close the ring back to the central control building. Dust, heat and humidity are handled by the cabinet; the fanless body has no fan filter to clog.

In water and desalination plants the same unit works as the Gigabit cell switch in a pump hall, tying variable frequency drives and PLC racks to the SCADA backbone, while a sibling -A unit at the plant core takes care of routing.
