Introduction

Figure 1-1 Departmental Switch Model 16B Front Panel

The Department Switch Model 16B is a 16-port Fibre Channel Gigabit

that provides connectivity for up to 16 Fibre Channel

switch
compliant device ports, and a fabric operating system for building
and managing a Fabric. A Fabric is an active, intelligent, interconnect
scheme for Fibre Channel server and storage nodes. Figure 1-1 shows
the front view of the switch. This chapter discusses:

DS-16B Switch Features

1-2

Departmental Switch Model DS-16B Hardware Reference Manual

WARNING

The DS-16B switch contains two power supplies. To remove all
power from the system, disconnect both power supply cords.

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 to add the switch’s Internet Protocol (IP)
address. The remainder of the switch’s setup is automated.

Intelligent – The switch’s fabric operating system allows discovery

•

of all connected devices and determines optimum data paths
without intervention, supporting up to 32 interconnected
switches.

Flexible – Modular design with multiple GBIC modules

•

supporting fiber 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
resulting in a worst-case data-transfer latency of less than two
microseconds from any port at peak Fibre Channel performance
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 32 switches can be interconnected for a large Fabric with
hundreds of Fabric connections.

Universal – DS-16B switch ports are designed to support F, FL and

•

E-port modes of operation with the software selecting the
optimum mode of operation.

Introduction

Performance

Manageability

A minimum aggregate routing capacity of 4,000,000 frames/sec is
specified for Class 2, Class 3, and Class F frames. Non-blocking
throughput of up to 8 x 100MBytes/sec (0.8 GBytes/sec) is provided.

A maximum switch latency of less than two microseconds is specified
for Class 2, Class 3, and Class F frames when the output port is free.

The unit may be managed in band or out of band via Telnet, via
SNMP, via SES or via the Web by connecting to the 10/100BaseT
Ethernet port.

Introduction

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

GBICs

SWL Fiber-Optic GBIC

Module

LWL Fiber-Optic GBIC

Module

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.

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.

The SWL fiber-optic GBIC module, with an SC connector color-coded
black, is based on shortwave length 850
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.

The LWL fiber-optic GBIC module, with SC connector color-coded
blue, is based on long wavelength 1300
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.

Unpacking the Switch

While unpacking the switch, check to make sure the following items
are included:

• Switch unit

• Requested GBIC modules

• Accessory kit containing the following:

• Power cord, if ordered

• Manuals

• Software Feature Guides

• Rubber mounting feet

Save packing materials in case you need to return the switch.

Cooling Requirements

Power Requirements

Cooling air is drawn into the chassis by four fans mounted near the
rear of the chassis, venting exhausted air through the front of the
switch.

Do not block the front or rear air vents. The switch must have free access to
ambient air for cooling.

Switch power connection is via switched connectors on the switch’s
front panel, as shown in Figure 2-1. The switch power requirements
are:

• Properly wired, earth-grounded outlet

• Input voltage: 85 – 265 VAC

• Total power: Up to 155 watts (depending on configuration, see

Appendix A, Specifications)

• Input line frequency: Nominally 47 to 63 Hz

The switch has an autoranging power supply that automatically
accepts voltages and line frequencies within its range. A green power
on indicator light is above the power switch.

Power Supply 2 Power Supply 1

Figure 2-1 Model DS-16B with Two Power Supplies

The switch meets IEC 801-5 surge voltage requirements, however, there is
no other provision for surge protection built into the switch’s power
supplies. An installation should include normal provisions to assure clean
power.

Site Considerations

Installation Considerations

The switch has optional mounting hardware to mount the switch in a
standard 19-inch rack. If the switch has had its rubber mounting feet
installed, they may need to be removed for a rack installation.

Standalone

Fiber Channel Cable Connections

Table 2-1 Cabling Connections

The switch is shipped in its standalone configuration. Adhesive
rubber feet are supplied if the switch is surface mounted. Rubber feet
installation is required for proper or safe switch operation.

To install the adhesive rubber feet:

1. Clean the four depressions at each corner of the chassis bottom so
that they are free of dust.

2. Remove the rubber feet from the sheet and place one in each
depression.

3. Firmly press the rubber feet in place.

All network cable connections are to the switch’s front panel. All
recommended cabling supports the switch’s 1.0625-Gbps transfer
rate, as shown in Table 2-1.

Fiber cable connections are made to the switch’s front panel using
standard dual SC plug connectors as shown in Figure 2-2.

Figure 2-2 Dual SC Fiber Optic Plug connector

The connectors are keyed and must be inserted into the GBIC
module’s connector in proper alignment. In most cases, one of the
two connector plugs is a different color to aid in proper connector
alignment.

Remove the protective plug from the GBIC. Do not force the fiber optic plug
into the GBIC module as you may damage the connector, the GBIC module,
or both. Make certain the fiber surface is clean, free of dust or debris, before
inserting the connector into GBIC module.

Ethernet Connection

Verif y Power-On Self Test (POST)

Connecting an existing Ethernet 10/100BaseT LAN to the switch via
the front panel RJ-45 connector gives access to the switch’s internal
SNMP agent and also allows remote Telnet and Web access for
remote monitoring and testing.

The connection is only for Telnet, SNMP agent and the Web-based Server
access. No Fabric connection is used via this connection.

When the switch is powered on it automatically runs the POST. From
the front panel the indications of a normal POST include a pause, a
momentary flashing of the lights, followed by a series of diagnostics
tests. See Power-On Diagnostics (POST) on page 4-5 for more
information.
