Rack Stability
WARNING: To reduce the risk of personal injury or damage to the equipment, be
sure that:
• The leveling jacks are extended to the floor.
• The full weight of the rack rests on the leveling jacks.
• In single rack installations, the stabilizing feet are attached to the rack.
• In multiple rack installations, the racks are coupled.
• Only one rack component is extended at any time. A rack may become
unstable if more than one rack component is extended for any reason.

Overview
The StorageWorks Fibre Channel SAN Switch 2/16 by Compaq is a
high-performance, 16-port, 2 gigabit (GB) Fibre Channel switch used to
interconnect storage devices, hosts, and servers in a Storage Area Network (SAN).
This chapter provides the following information:
•Features
• Firmware and hardware summaries
• Field-Replaceable Units (FRUs)
SAN Switch 2/16 Features
Read the following sections for feature-specific information.
Firmware
The SAN Switch 2/16 operates using Fabric Operating System™ firmware
Version 3.0.x. The firmware supports:
• High-speed data traffic using Inter-Switch Link (ISL) trunking technology
• Automatic re-routing through the Fabric Shortest Path First (FSPF) algorithm
• Application Programming Interface (API); a protocol that allows applications
to interface with switch services.

1–2 Fibre Channel SAN Switch 2/16 Installation Guide
Overview
• Zoning functionality, provides a means to allocate storage controllers to groups of
computers. Allows you to create logical subsets of the fabric to accommodate
closed user groups or to create functional user groups within a fabric.
For more information refer to the StorageWorks by Compaq SANworks Zoning
User’s Guide, PN AA-RQ6YA-TE.
• Per port statistics help technicians diagnose and isolate problem ports without
disrupting switch operations
• Error detections and fault isolation, automatically disables failing ports and
restarts when the problem is resolved
• Industry standard Management Information Base (MIB) support
• Automatic self-discovery, discovers and registers host server and storage devices.
Hardware
SAN Switch 2/16 consists of the following components:
• A 1 Unit (U) chassis, designed for mounting in a 19-inch rack, with forced-air
cooling that flows from the back of the switch to the front
• 16 optical ports, compatible with Small Form Factor Pluggable media (SFPs)
• One RS-232 Serial port (DB9 connector) on the front panel.
• One IEEE compliant RJ-45 connector on the front panel for use with 10/100 Mbps
ethernet or in-band
• A total of 36 LEDs
— One Power Switch LED on left of the front panel
— One Port Status and Port Speed LED for each of the sixteen ports
— One the Power Supply LED on the back of the Power Supply
— One Port Readiness LED on the Back Panel
• Universal input power supply with AC switches and built-in fans. (The power
supply plugs into internal blind-mate connectors when installed in the chassis.)
• Two fan trays, each containing two fans. Air is pulled in through the rear intake
and pushed out through the vents in the front panel. The fans provide adequate
cooling for the maximum switch power rating.
• Three digital thermometers, capable of sensing a temperature range from -55 °C
to +125°C, in 0.5°C increments

Overview
• A field-replaceable motherboard completely enclosed in an Electro-Magnetic
Interference (EMI) enclosure tray, with logic and chassis ground connected to the
chassis, and an embedded processor that processes frames up to 1024 bytes.
• A real-time clock (RTC) with a 10-year battery and 56 bytes of NVRAM.
SAN 2/16 Front Panel
Figure 1–1 shows the front panel of the SAN Switch 2/16. The front panel houses the
Serial port, Ethernet port, fiber optic ports with corresponding LEDs, and the power
switch LED.

Optical Ports
All switch ports support full fabric capability. Full fabric allows the Fibre Channel
SAN Switch 2/16 to link or cascade to other StorageWorks Fibre Channel switches
running v2.6x and above, building a highly scalable SAN fabric. The Fibre Channel
SAN Switch 2/16 supports F-port, FL-port, and E-port connections and Distributed
Name Server (DNS).
The ports on the front panel of the SAN Switch 2/16 are color-coded in groups, with
four purple ports alternating with four unmarked ports, to indicate which ports can be
used in the same ISL trunking group (see “ISL Trunking,” described next). Each port
automatically negotiates to the highest common speed.
The ports are capable of operating at 2.125 Gbps or 1.0625 Gbps. Each port conforms
to the American National Standards Institute (ANSI) Fibre Channel, FC-PI
specification for Fibre Channel SFP transceivers.

Overview
ISL Trunking
ISL trunking is a Fabric OS feature that enables distribution of traffic over the
combined bandwidth of up to four ISLs between two directly adjacent switches, while
preserving in-order delivery. For specific information about ISL trunking, refer to the
StorageWorks by Compaq ISL Trunking User Guide, Part Number AA-RR82A-TE.
SFPs
The ports connect to SFP media. SFPs are universal and self-configuring.
SAN 2/16 Rear Panel
Figure 1–2 shows the rear panel of the SAN Switch 2/16. The rear panel houses the
fan trays, power supply, and switch status LED. Each power supply also has an LED
that indicates the status. The power supply, fan trays, and motherboard are all Field
Replaceable Units (FRUs).

Fibre Channel SAN Switch 2/16 Installation Guide 1–5
Overview
Field-Replaceable Units
The power supply, fan trays, and motherboard can all be replaced in the field,
without the use of special tools. The switch continues operating during the
replacement of a fan tray or power supply, if they are replaced one at a time. The
switch must be turned off during replacement of the motherboard. To simplify
replacement, the switch has a minimum of internal cables and no jumpers or
hardware settings. Replacement instructions are provided with all replacement
units ordered.
The right and left fan trays are identical and fit into either fan tray slot. The fans in
the fan tray on the left (front view) are identified by the Fabric OS as fans #1 and
#2. The fans in the fan tray on the right are identified as fans #3 and #4 by the
Fabric OS.
