5.3.1 Fiber Loop Modules
Two types of fiber optic modules are available to use to transmit and receive communication with the SK-NIC. See Figure 5.4.
Figure 5.4 Types Fiber Loop Modules
The SK-FML (Fiber-Optic Multi-Mode) and SK-FSL (Fiber-Optic Single-Mode) are plug-in fiber loop modules. The two types of fiber
optic modules are used as one channel to transmit or receive communications with the SK-NIC, ARCNET communication circuit.
The following describe the two types of fiber optic modules.
• The SK-FML is a fiber module that allows the multi-mode fiber to network between nodes.
• The SK-FSL is a fiber module that allows the single-mode fiber to network between nodes.
Each fiber loop module can Transmit (TX) and Receive (RX) fiber-optic cable connecting to the SK-NIC. Up to two fiber loop cards can
be added to the SK-NIC, and both cards may be combined in the same configuration. See Figure 5.5.

Accessory Mounting Kits
SK-NIC can be mounted within the IFP-300/ECS cabinet or in an accessory cabinet. Accessory cabinets include a small cabinet with
door, key, and mounting hardware. An accessory kit is available if you want to install the SK-NIC outside of the IFP-300/ECS cabinet.
The accessory kit part number is:
1. 5815RMK -- which includes the enclosure with mounting bracket.
5.3.2 SK-NIC Installation
The SK-NIC is designed to mount on one of the SLC standoff sets inside the cabinet or remotely using the accessory cabinet.
Use the following steps to properly mount the SK-NIC inside the IFP-300/ECS.
1. Place the SK-NIC on one of the SLC expander standoff sets.
SK-FSL Single-Mode Fiber
SK-FML Multi-Mode Fiber
