System Components
The motherboard is enclosed in an air-cooled chassis which may be either mounted in a
standard rack or used as a standalone unit. The chassis includes one or two power
supplies, a fan tray, an RJ-45 Ethernet connection for switch set up and management, and
a serial port. The serial port is used for recovering factory settings only and initial
configuration of the IP address for the switch if default address is not known.
Fabric Operating System
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.

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.
