Chapter

Overview

The SilkWorm 2200 Family of switches are low cost, high-performance 16-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

sixteen 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.

All sixteen ports are configured as a removable GBIC slots, providing the flexibility to

configure physical media such as short-wave length optical, long-wave length optical or

copper.

Designed as a 1.5U 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 2210 Loop Switch

The SilkWorm 2210 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 2210 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 2210 is ideally

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 2210 can be upgraded to a 2250 using the already deployed hardware.

The SilkWorm 2240 Entry Fabric Switch

The SilkWorm 2240 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 2240, 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 2240 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 2240 can be upgraded to a SilkWorm 2250 by enabling

preloaded software with a software license key.

Overview

The SilkWorm 2250 Full Fabric Switch

The SilkWorm 2250 supports all of the functionality of the SilkWorm 2240 model with the

addition of Full Fabric capability. Full Fabric allows the SilkWorm 2250 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 2250 supports

F, FL, and E port connections and Distributed Name Server (DNS).

Setup and Installation

Note: The switch is not designed to interoperate with devices using an

Open Fibre Control optical interface.

Fiber cable connections are made to GBICs located on the front panel of the switch using

standard dual SC plug connectors as shown in Figure2-5.

Figure 2-5 Dual SC fiber optic plug connector

The connectors are keyed and must be inserted into the GBIC module connector in proper

alignment. In most cases, one of the two connector plugs is a different color to aid in

proper connector alignment.

Note: Remove the protective plug from the GBIC. Do not force the fiber

opticpluginto the GBIC module as you may damagetheconnector,

the GBIC module, or both. Make certain the fiber surface is clean,

free of dust or debris, before inserting the connector into GBIC

module.

Copper cables use a High Speed Serial Data Connection (HSSDC) connector.

SilkWorm 2200 Family Reference Manual 2-5

Setup and Installation 2

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 page7.

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

SilkWorm 2200 Family contains a serial port for initial configuration and an Ethernet

connection for 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 2200 Family of switches have 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.

2-6 SilkWorm 2200 Family Reference Manual

Setup and Installation

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. Turn on 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 2200 Family of switches is designed for maintenance-free operation. It

contains self-diagnostic capabilities that provide switch status and operating statistics. In

the case of a failure, the self-diagnostics aid in isolating the problem.

The Silkworm 2200 Family of switches have loopback paths 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.

This test requires external cables to be looped from one port to another.

Diagnostic Tests

Available tests which are run from the local telnet port are listed below, along with the

command to initiate each. See Fabric OS, for detailed information oncommands.
