Switch Features
The switch is a high-performance Fibre Channel Gigabit Switch with the following
features:
■Simple –Easy setup and configuration. After Power-On Self-Test (POST), you
need only add the switch’s Internet Protocol (IP) address. The remainder of the
switch’s setup is automated.
■Intelligent – The fabric operating system allows discovery of all connected
devices and determines optimum data paths without intervention, supporting up
to 239 interconnected switches.
■Flexible – GBIC modules support fiber and copper transmission media. The
switch’s modular construction gives the switch a range of flexibility in creating,
upgrading, maintaining, and configuring a Fabric.
■Reliable – Highly integrated, reliable, multifunction (ASIC) devices are used
throughout the switch.
■High performance – Low-latency, high-performance design requires no CPU data
path interaction resulting in a worst case data transfer latency of less than two
microseconds from any port to any port at peak Fibre Channel bandwidth of 100
MB/sec. The latency may differ when the destination or device is a loop.
■Automated congestion management – Virtual channels lets the switch use
sophisticated congestion management techniques that are performed
automatically by the switch.
■Cascading – You can cascade switches for large Fabric support. Up to 239
switches can be interconnected for a large Fabric with hundreds of Fabric
connections.
■Compatibility – SilkWorm 2400 has been designed to inter-operate with the
SilkWorm 1000 series switches using a compatibility mode.
■Universal – Switch ports are designed to support F,FL and E-port modes of operation
with the software selecting the optimum mode of operation.

The fabric operating system is tuned for each installation. The system provides a large
number of commands and libraries to manage real time tasks.
GBICs
The switch accommodates up to eight GBIC modules. All interfaces have status lights
visible from the front panel giving a quick, visual check of the GBIC’s status and
activity.
GBIC modules supported are the ShortWave Length (SWL) and LongWave Length
(LWL) fiber-optics, and Copper (Cu) versions.
If your installation requires installing less than eight GBIC modules, the unused port
positions are protected by a metal, spring-loaded door.
SWL Fiber-Optic GBIC Module
The SWL fiber-optic GBIC module, with SC connector color-coded black, is based on
short wavelength lasers supporting 1.0625 Gbps link speeds. This GBIC module
supports 50-micron multi-mode fiber optic cables, with cables up to 500 meters in
length.The GBIC module is shipped with a protective plug in place and should remain in
place if no fiber optic cable is connected to the port. Figure 1-2 shows a GBIC module.
Figure 1-2 Short wavelength Laser (SWL) fiber optic GBIC module
The SWL GBIC module uses a Class 1 laser, which complies with the 21 CFR, subpart
(J) as of the date of manufacture.

Chapter 1 Introduction
1-4
LWL Fiber-Optic GBIC Module
The LWL fiber-optic GBIC module, with SC connector color-coded blue, is based on
long wavelength 1300nm lasers supporting 1.0625 Gbps link speeds. This GBIC module
supports 9-micron single-mode fiber. Cables up to 10 kilometers in length with a
maximum of five splices can be used. The GBIC module is shipped with a protective
plug in place and should remain in place if no fiber optic cable is connected to the port.
