IEM-3300-8S Description

The IEM-3300-8S is a Cisco Catalyst IE3300 expansion module for adding fiber links to industrial DIN-rail switch cabinets. It provides eight 100/1000Mbps SFP ports, takes the system to 18 total ports, and draws 19W of module power. The module carries no PoE ports, installs one per base system, and is not hot-swappable.

Application Scenarios

Fiber Links To Remote Cabinets

A plant or campus cabinet can use the eight SFP ports to reach remote cabinets and equipment rooms over fiber, with 100M or 1G optics selected for each link.

IE3400 Base With Fiber Expansion

An IE3400 modular base switch can take the module as well, adding eight SFP ports, although that pairing removes SGT/SGACL advanced security from the IE3400.

IEM-3300-8S and IEM-3300-8T both add eight ports for 18 total system ports, but IEM-3300-8S gives all eight to 100/1000Mbps SFP, while IEM-3300-8T has eight copper RJ45 ports; the SFP module draws 19W against 6W. Sites that need six copper ports and only two SFP ports on the same 18-port total move to IEM-3300-6T2S. Designs that need 16 expansion ports, 14 copper and 2 SFP, move to IEM-3300-14T2S, which takes the system to 26 total ports and is wider at 3.6 in. against 2.6 in.

Ordering Checklist

  • Catalyst IE3300 hosts: Pair the module with non-PoE IE-3300-8T2S and IE-3300-8T2X base switches. IEM-3300-8S= is one of the five non-PoE modules these bases accept.
  • Catalyst IE3400 hosts: Pair the module with IE3400 modular base switches only if losing SGT/SGACL advanced security is acceptable. IE3300 expansion modules also fit IE3400 bases, but the combination removes that security feature from the IE3400.

Questions & Answers

  • What is the total power draw of IEM-3300-8S with a non-PoE base, and does a PWR-IE50W-AC= cover it?

    Cisco measures non-PoE module power at 12V, and IEM-3300-8S= draws 19W. A non-PoE base plus this module reaches up to 42W, which stays inside the 50W of a PWR-IE50W-AC= power supply. Size the cabinet supply on that 42W figure.
  • Does IEM-3300-8S offer PoE, 90W PoE or advanced hardware features, and is IE-3300-8T2C a supported base?

    IE-3300-8T2C is a listed base for IEM-3300-8S in Cisco's IE DIN-rail FAQ. The FAQ marks PoE and PoE+, 90-W PoE and advanced hardware features as No for its 8 SFP Gigabit ports. The module is a data-only fiber expansion.
  • What is the MTBF of IEM-3300-8S?

    The MTBF of IEM-3300-8S is 6,810,960 hours. Use this figure when planning spare modules and service intervals for a cabinet with 8 SFP fiber links. The module draws 19W, weighs 2.0 lb and mounts on a DIN rail like the other IE3300 expansion modules.
  • Can IEM-3300-8S be fitted next to another expansion module on one base switch?

    No. A base switch takes one expansion module at a time, and IEM-3300-8S is not hot-swappable. Do not attach it while the switch is energized. Power the base off before fitting IEM-3300-8S, then add SFP transceivers to the 100/1000Mbps SFP ports and connect the fiber links. The module has no PoE and no copper ports.
