Overview
The SilkWorm 2000 Entry Family of switches are low cost, high-performance 8-port,
gigabit Fibre Channel switches used to interconnect storage devices, hosts, and servers in
a Storage Area Network (SAN). The switches offer full non-blocking performance for all
eight ports with each port able to deliver 100 MB/s full duplex. Cut-through routing
guarantees a maximum latency of 2 microseconds from switch port to switch port.
Seven of the eight ports on the SilkWorm 2000 Entry Family switches are fixed short-
wave length optical media for interconnecting devices at distances up to 500m. One port is
configured as a removable GBIC slot providing the flexibility to configure other physical
media such as long-wave length optical or copper.
Designed as a 1U high device, the switches may be installed in industry standard EIA
racks or in a table-top environment. Overall cost of ownership is reduced through the use
of high reliability components, continuous monitoring of environmental components (fan
status and temperature), and a Single Field Replaceable Unit (FRU) design strategy.
The SilkWorm 2010 Loop Switch
The SilkWorm 2010 Loop Switch is configured as a high-speed interconnect for fiber-
channel arbitrated loop (FC-AL) environments. As an alternative to hub-based solutions,
the SilkWorm 2010 offers a true switching environment that provides enhanced
performance, increased availability through better fault isolation, and investment
protection through migration to full fabric topologies. The SilkWorm 2010 is suited for
low-end SAN environments with hosts and devices that only support FC-AL, such as NT
clusters. By enabling the embedded software with a software license key, the SilkWorm
2010 can be upgraded to a 2050 using the already deployed hardware.
The SilkWorm 2040 Entry Fabric Switch
The SilkWorm 2040 provides a low-cost fabric alternative for entry-level SAN environ-
ments. It delivers true switch fabric scalable performance in a simple switch topology.
Using the SilkWorm 2040, an entry level SAN can be implemented using a single or dual
switch configuration. Each switch can allow one other fabric switch to be connected to
the SAN in addition to storage devices. This provides an additional expansion step to
extend fabric configurations before moving to the full fabric design.
The SilkWorm 2040 is the dominant configuration for most entry-level SANs. Its
uniqueness allows simple fabric connectivity without the intricacy of a cascaded mesh of
fabric switches. It provides all of the benefits of a switched environment while keeping
the simplicity of the entry-level SAN configuration. As the SAN connectivity
requirements grow, the SilkWorm 2040 can be upgraded to a SilkWorm 2250 by enabling
preloaded software with a software license key.

The SilkWorm 2050 Full Fabric Switch
The SilkWorm 2050 supports all of the functionality of the SilkWorm 2040 model with the
addition of Full Fabric capability. Full Fabric allows the SilkWorm 2050 to be linked or
cascaded to other SilkWorm fibre channel switches to build a highly scalable SAN fabric
capable of supporting thousands of attached storage devices. The SilkWorm 2050 supports
F, FL, and E port connections and Distributed Name Server (DNS).

Setup and Installation
Power Supply
Note: The SilkWorm 2000 Entry Family does not have a power switch. When the
power cord is connected to the switch, the switch is powered on.
The SilkWorm 2000 Entry Family switch is ready to go once the unit is plugged in. The
SilkWorm 2000 Entry Family switch meets IEC 61000-4-5 surge voltage requirements.
See Appendix A for specific information on power requirements for the SilkWorm 2000
Entry Family switch.
Figure 2-1 SilkWorm 2010/2040/2050 Switch
GBIC Modules
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 switch port’s status and
activity.
GBIC modules supported are the short wavelength (SWL) and long wavelength (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 that covers the opening.

Initialize the Switch
To initialize the switch:
1. Insert the GBICs into the the GBIC ports and connect the Fibre Channel cable to the
GBIC. This may be done before or after the switch is initialized.
2. Connect the power cord to the AC module of the switch. The switch automatically
performs a Power On Self Test (POST). The POST will take approximately 2.5 min-
utes.
Note: If a switch boot failure occurs, the switch must be taken offline for
repair or replacement. Contact your switch supplier for assistance.
3. If the factory set IP address is compatible with your network, connect the Ethernet
connection.
Note: The factory set IP address is: 10.77.77.77. The Subnet Mask is:
255.255.255.0
If the factory set IP address is not compatible with your network, connect the serial
port connection, then follow the procedure to set the IP address on page 3.
4. Monitor the status indicators for port status, see “Status Indicators” on page4.
If a malfunction occurs during POST, specific error messages are written to the system
error log and can be analyzed via a telnet session when the POST session completes. If the
malfunction prohibits the switch from completing the boot process (fatal error), the switch
stops the boot process. If the switch does not fully boot, the switch prompt will not be
displayed when the serial port is connected.
Serial Port and Ethernet Connections
The SilkWorm 2000 Entry Family contains serial port and Ethernet connections for initial
configuration and remote monitoring and testing.
Ethernet Connection
An Ethernet connection must be established to obtain access to the internal SNMP agent
in the switch and local area network. Once the connection is made remote Telnet and Web
access is made available. To establish an Ethernet connection, connect to an existing
Ethernet 10/100Base-T local area network (LAN) via the front panel RJ45 connector.
Note: Remove shipping plug from the Ethernet port before inserting
Ethernet cable.
Serial Port Connection
The SilkWorm 2000 Entry Family has a serial port for initial configuration of the IP
address. This port may also be used for service purposes. The serial port should not be
used during normal operation.
Note: Remove the dust cover from the serial port before inserting the
serial cable.
Note: Do not use the serial port during normal operation or for regular
maintenance. Remove the serial port cable and, using the dust
cover supplied with the switch, cover the port during normal opera-
tion of the switch.

SilkWorm 2000 Entry Family Reference 2-3
Setup and Installation 2
To set the IP address on the switch for normal Ethernet access, perform the following
initial procedure:
1. Attach the provided serial cable between the serial port on the switch and an RS-232
serial port on your laptop or host computer. The cable is wired with only pins 2, 3 and
5 wired straight through.
NOTE: If needed, the adapter can be removed to allow for RJ45 serial connection to
your host computer.
2. Plug in the switch and wait for the power on self test (POST) to complete. POST is
complete when all LED activity has stopped, this takes approximately 2 minutes.
3. Disable all serial communication programs running on your computer, such as sync
programs for a PDA.
4. Run a terminal emulation program such as Hyperterm on NT/W95, or TERM in a
Unix environment.
5. Configure the terminal for 9600 Baud, 8 Data Bits, No Parity, 1 Stop Bit, and no
flow control. Click OK.
6. Press <return> to get a prompt.
7. If prompted, provide a login and password. The default is login = admin and the
password = password
8. At the prompt, type the command ipAddrSet,then press <return>
9. When prompted, provide the IP Address, Subnet mask, and Gateway Address in the
standard IP form of xxx.xxx.xxx.xxx.
NOTE: For now only edit the Ethernet addresses, not the Fibre Channel address.
10. When prompted type yand press <return> to apply the new values.
11. Power down the switch and disconnect the serial cable (and adapter, if used). Connect
the switch to a 10/100BaseT Ethernet connection.
12. Power up the switch. IP based management (telnet, SNMP or WebTools) can now be
accessed by using the newly defined IP address.
13. Record the IP address on the label provided on the switch.

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. Contact your switch supplier for the optional rack installation kit.
Rackmount Safety Guidelines
In a rackmount installation, follow these safety guidelines:
•When installing a switch in a closed or multi-rack assembly, make certain the air
temperature, measured at the front panel, does not exceed 40° Cduring operation.
•Ensure that the airflow available to the switch is at least 300 cfpm.
•Verify that the switch installation, both with the slides closed and fully extended, does
not unbalance the rack or exceed the rack’s mechanical limits.
•Verify the supply circuit, line fusing, and wire size are adequate. Refer to the switch’s
nameplate for its power requirements.
•Verify that all equipment installed in the rack has a reliable ground connection. Do
not rely on connection to a branch circuit, such as power strips.
Route and support the power cord to ensure that the switch moves freely on its slides
without crimping or damaging the power cord or interfering with other equipment and
cabling installed in the rack.

Diagnostics
The Silkworm 2010/2040/2050 switch is designed for maintenance-free operation. It
contains self-diagnostic capabilities that provide switch status, operating statistics, and, in
the case of a failure, aid in isolating the problem.
Loopback paths are incorporated into the switch hardware. Internal Fibre Channel port
logic functions and the paths between the interfaces and central memory are verified by an
internal loopback path test within the switch. An external loopback path test that includes
the main board, fixed media, and the GBIC module checks installed fiber cables and port
fault isolation in cross-port configurations, requires cables to be looped from one port to
another.
