Departmental Switch Model DS-16B Hardware Reference Manual
Introduction
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 an RJ-45 Ethernet connection for switch set up and
management.
Fabric Operating
System
Included with the switch is a fabric operating system tuned for each
installation. The system provides a large number of commands and
libraries to manage real time tasks. See the Departmental Switch Model
DS-8B or DS-16B Fabric OS Reference Manual for details about software
features.
GBICs
The switch accommodates up to sixteen GBIC modules. All interfaces
have status lights visible from the front panel giving a quick, visual
check of the switch port’s status and activity.
GBIC modules supported are the short wavelength (SWL) and long
wavelength (LWL) fiber-optics.
If your installation requires installing less than sixteen 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 an SC connector color-coded
black, is based on shortwave length 850
µm lasers supporting 1.0625
Gbps link speeds. This GBIC module supports 50-micron,
multi-mode fiber-optic cables up to 500 meters in length. The SWL
GBIC module uses a Class 1 laser, which complies with the 21 CFR,
subpart (J) as of the date of manufacture.
LWL Fiber-Optic GBIC
Module
The LWL fiber-optic GBIC module, with SC connector color-coded
blue, is based on long wavelength 1300
µm lasers supporting 1.0625
Gbps link speeds. This GBIC module supports 9-micron single-mode
fiber-optic cables up to 10 kilometers in length with a maximum of
five splices.
