SilkWorm 2100 System Components
The Silkworm 2100 switch is comprised of several components:
• Main Board
• Fabric OS
TM
• Gigabit Interface Converter (GBIC) Modules
Main Board
The main board is enclosed in an air-cooled chassis that includes one or two power
supplies, a fan tray, an RJ-45 Ethernet connection for switch set up and management, and
a serial port for recovering factory settings and initial configuration of the IP address. This
unit can be mounted in a standard rack or used standalone.
WARNING
The SilkWorm 2100 can be configured with two power supplies. To
remove all power from the system, disconnect both power cords.
Fabric OS
Fabric OS provides commands and libraries to manage real time tasks; it is individually
tuned for each installation.
GBIC Modules
The Silkworm 2100 switch accommodates up to eight GBIC modules. If less than
eight GBIC modules are used, the unused port positions are protected by a metal,
spring-loaded door.
The main board module is structured to accommodate a universal port. The universal port
(U-port) supports attachment to the NL_port devices associated with an arbitrated loop.
Attachment to NL_port devices is via GBIC. The front panel of the SilkWorm 2100 switch
includes indicator lights that display port status. See Status Indicators on page 3-3.
GBIC modules are available in ShortWave Length (SWL) and LongWave Length (LWL)
fiber optics, and Copper (Cu).
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; it should remain in place if no
fiber optic cable is connected to the port. The SWL GBIC module uses a Class 1 laser that
complies with the 21 CFR, subpart (J) as of the date of manufacture. An SWL fiber optic
GBIC module is shown Figure 1-1.
