1Introduction
This guide describes how to install and manage the 30-10022-01 loop switch.

Overview

The 30-10022-01 loop switch is a 12-port, speed agile switch. Enclosed in a 1U, half-rack form factor enclosure, the switch is controlled by firmware loaded into the on-board flash mem ory. The switch is designed as a central interconnect following the ANSI FC-AL standard. Devices are connected to the switch through Small Form-factor Pluggable (SFP) transceivers and cables.
Each port independently supports 1 or 2 Gb/s of Fibre Channel bandwidth. Automatic port configuration allows individual port access using automatic speed detection to connect devices based on their supported speed. Smart synchronization validates proper initialization, checking signal integrity and certain errors, such as OS and CRC, before allowing access to other Fibre Channel devices. During normal operational when a change notification (LIP) is sent, the Bad Device Recovery feature detects non-Fibre Channel compliant devices and removes them from participation. Further validation continues to either bypass the port or allow access back into the Fibre Channel network. Proper device notification is provided through the switch’s event log.
The switch also features automatic-configuration capability, which allows for IP address assignment using DHCP- compatible networks. Once the switch is operational, complete switch configuration and management is available through the intuitive, graphical-based Web Manager interface. In ad dition, the switch features granular change notification management, retained system configuration parameters, and a Command Line Interface (CLI).

Installation Preparation

After receiving the switch, perform the following steps to ensure that the switch and other contents arrived safely.
To unpack the switch:
1. Inspect the outer shipping container for any damage that may have occurred in shipp ing. Report any sign of damage to the appropriate shipping agency.
2. Remove the switch and cables from the shipping co ntainer; save the shipping container, foam, and antistatic bags—returning the switch in any other container is not advised.
Make sure the following parts are included:
• 30-10022-01 switch unit
• RS-232 null-modem serial cable
•Power cable
• Self-adhesive pads (4)
3. Inspect the switch thoroughly. If any signs of damage are present, notify a sales representative and/or the shipping agency.

Switch Installation

The switch can be installed in a rack or placed on a desktop.

Rack Installation

Guidelines for Mounting Equipment in a Rack
When installing equipment in a rack, give careful consideration to the following factors:
The operating ambient temperature of rack-mounted equipment must not exceed the maximum rated ambient temperature, which is indicated in this installation guide. (See
“Operating Conditions” on page 41.)
The air flow clearances specified in this installation guide must be maintained within the rack. (See “Operating Conditions” on page 41.)
The AC supply circuit for rack-mounted equipment must be capable of supplying the total current specified on all the labels of the rack-mounted equipment.
All AC power supply connections must be properly earthed. To ensure the integrity of the earth connection, special attention must be given to connections that are not directly connected to the branch circuit (for example, power strips).
The rack-mounting hardware has been carefully selected to properly support the equipment. Any alternate rack-mounting hardware must provide equal or superior support.
Plan the device installation starting from the bottom of the rack cabinet. Install the heaviest device in the bottom of the rack cabinet.
For information on environmental requirements, see “Operating Conditions” on page 41.

Switch LEDs

The switch incorporates three sets of Light-Emitting Diodes (LEDs) to indicate Ethernet, switch, and port status:
1. Ethernet LEDs – two separate LEDs indicating the network connection status.
2. System LEDs – three separate LEDs indicating the switch’s status.
3. Port LED – one multi-colored LED per port indicating the po rt’s status.

SFP Compatibility

SFPs are “hot-pluggable” into the switch, which allows host computers, servers, and storage devices to be added dynamically without requiring power removal from the switch or any connected devices.
The switch supports Small Form-Factor Pluggable (SFP) modules that comply with the SFP specification as produced by the MSA consortium and have passed qualification testing.
The following manufacturers offer 4Gb, 2Gb, and 1Gb optical, shortwave SFPs in both RoHS and non- RoHS versions:
Intel
Finisar
JDS Uniphase
Agilent
9101112

Installing an SFP

Plugging an SFP into the switch will automatically send a change notification to indicate that the device is ready to begin initialization.
CAUTION: Forcing an SFP into a port may damage the SFP and/or port.
To insert an SFP:
1. Remove dust covers or plugs from the SFPs, if provided .
2. Slide the SFP into the port, ensuring cor rect polarity, until the latch clicks into place.

Removing an SFP

To extract an SFP:
Determine what kind of extraction mechanism the SFP has and remove the SFP a s follows:
If the SFP has a removal tag, remove the cable from the SFP and then pull the removal tag outward and toward the side of the SFP with the tag.
30-10022-01 loop switch user guide 9
If the SFP has a small plastic slider on the top or bottom, remove the cable from the SFP and then push in the slider and hold while pulling out the SFP.
If the SFP has a bale (small metal clasp), remove the cable from the SFP and then unlatch, pivot, and pull the bale.

Attaching a Device to the Switch

To attach a device:
1. Make sure that the device is FC-AL compatible.
2. Attach a cable to the device.
3. Attach the other end of the cable to an SFP.
4. Make sure that the device and switch ar e operationa l and set to the same spe ed.
10 Switch Installation

Booting the Switch and Attached Devices

The following procedure is recommended when booting the switch and attached devices. To boot the switch and attached devices:
1. Power on the storage device s.
2. Insert the plug end of the switch’s power cord to a properly g rounded p ower source.
3. Insert the power cord’s IEC connector end into the switch’s power receptacle. The switch powers on and runs Power-On Self-Test (POST) diagnostics to verify the
fundamental integrity of the switch ports. All switch LEDs turn on (LEDs illuminate). Then, excluding the Ethernet Link and Power LEDs, the LEDs turn off (LEDs extinguish). Once the switch is operational, the LEDs display current status as described in “Switch LEDs” on
page 7.
NOTE: The power cord’s IEC connector plug serves as the switch’s disconnect device. To cycle
power to the switch, remove and reconnect the switch’s power cord.
4. Power on any other switches connected to the SAN.
5. For certain applications, switch configuration must be co mpleted befo re contin uing with the next step. For information regarding switch configuration, see : Switch Management.
6. After all switches have initialized, power on the hosts or storage contro llers. The network initializes.
NOTE: FC-AL compatible nodes must perform initialization procedures upon power-up in order to
function properly. It is the responsibility of the Fibre Channel driver software on FC-AL nodes to perform this initialization.
7. Check all port LEDs. The network should be fully operational at this point. However, it is appropriate to ensure that
proper discovery has taken place and all required devices are participating in the network. Some host bus adapters may provide this level of functionality or it might be resident in the application software on the host operating system.

3 Switch Management

The switch incorporates two distinct interfaces for managing and monitoring purposes:
The Web Manager interface provides an intuitive graphical user interface that enables users to quickly
check switch status or modify switch settings in a visual environment.
The Command Line Interface (CLI) provides flexibility and additional functionality for advanced users.
For a list of CLI commands, see : CLI Quick Reference on page 43. For additional information on the CLI, see the HP EVA 4000/6000/8000 30-10022-01 loop switch CLI reference guide.
While these interfaces provide nearly identical functionality, this guide describes how to use the Web Manager interface for switch configuration and monitoring, unless otherwise noted.

Getting Started

This section explains how to configure the switch’s Ethernet network settings prior to using the Web Manager. Once the switch’s network settings are configured, you can use the Web Manager for switch configuration and monitoring.

Configuring the Network Interface

Before using the Web Manager, ensure that the switch’s Ethernet network parameter settings are correct for the network configuration. The switch ships with the following default IP settings:
IP Address: 192.168.0.10
Netmask: 255.255.255.0
Gateway: 192.168.0.1
To adjust these settings to open the Web Manager, connect to the switch using the provided null-modem serial cable and enter the new network settings.
To connect through a serial interface:
1. Attach one end of the included null-modem cable to the co mputer’s RS-232 serial port and attach the other end to the switch’s RS-232 serial port.
2. Open a terminal session through a serial termin al emulation program (su ch as HyperTerminal®) with the appropriate serial port (for example, COM1) and the following serial port parameters:
• Bits per second: 115200
• Data bits: 8
•Parity: None
•Stop bits: 1
• Flow control: None
3. If using HyperTerminal, press E If using the tip command on a UNIX workstation, do the following:
a. View the /etc/remote file and create an alias similar to Hardware but with the serial
port parameters above (suggested name: Switch).
b. Use the tip command to establish a connection through the created alias, for
example tip switch.
4. Type li and press E
5. Type the password at the prompt and press E
6. From the serial terminal emulation pr ogram, type config network ip and press ENTER. The switch’s current IP parameters are displayed with a prompt for entering the IP address.
7. Change the IP address and p ress E

12. Attach the computer to the switch’s 10/100 Ethernet connector by doing one of the following:
• Attach an Ethernet RJ-45 cross-over cable directly between the computer and the switch.
• Attach two Ethernet RJ-45 twisted pair cables from the computer and the switch into an operational Ethernet patch panel or hub.
DHCP IP Address Assignment
For Dynamic Host Configuration Protocol (DHCP)-enabled environments, you can enable the switch to acquire an IP address from a DHCP server automatically. This feature is disabled by default.
To enable DHCP IP address assignment:
1. Use a serial terminal emulation program to connect to the switch as described in “Configuring
the Network Interface” on page 13.
2. Type the password at the prompt and press E
3. From the Root menu (root), type config network dhcp and press E
4. Enter 1 to enable DHCP and press E
NOTE: Once DHCP is enabled, the switch will automatically obtain an IP address from the DHCP
server. You will need to know this IP address in order to access the switch through the Web Manager. You can locate the new IP address by attaching a serial cable and using a serial terminal emulation program or contacting your network administrator.

Port Utilization and Health
This part of the Web page displays each port number, the port’s cu rrent health status, and a vertica l bar indicating the port utilization.
Port utilization measures the amount of traffic passing through a port over a period of time. The port utilization indicated by the vertical bar reflects the average of the sum of the transmit (Tx) and receive (Rx) utilization for that port.
A port number is displayed in one of four colors depending on the port’s current health:
Port Color Indication
Green An SFP is inserted into the port and a device is connected to the SFP. Yellow May indicate one of the following conditions:
• The port is bypassed. An SFP may be inserted in the port but there may not be a device connected to the SFP.
• The port is in loopback mode. There is no device connected to the port. The transmit and receiver are connected together on the SFP transceiver.
• The switch is receiving an F8 Failure notification, so the port is bypassed to allow remaining devices to proceed with initialization.
• The port is a failover link in a cascade and is not currently active.
Red May indicate one of the following conditions:
• An SFP transmitter fault has been detected.
• Ordered sets are being transmitted, so traffic cannot be passed through the port.
• A data timeout fault has been detected.
• A loss of received signal amplitude from the device has been detected.
• A loss of word synchronization for a specified time has been detected, which may be caused by poor signal strength, intermittent line conditions, and so on.
Gray May indicate one of the following conditions:
• The port status cannot be determined.
• There is no SFP connector inserted in the port.
or power is cycled, this value is reset.
Port utilization is measured by a vertical bar that moves upwards as utilization increases. The vertical bar has the three distinct levels of utilization:

Figure 15 Advanced Statistics Low-level Link page
Diagnostic Description
Sync Loss The number of times loss of word synchronization has occurred on the port for a
specified time. Synchronization loss occurs when the port stops receiving a signal for a period of time. Possible causes include:
• Poor connections or signal strength
• Rogue devices
• Intermittent hardware failures or line conditions.
Invalid OS The number of invalid ordered sets that have been detected. Ordered Set (OS) or word
errors can occur in bursts, which can potentially cause system performance issues. Possible causes include:
• Poor connections or signal strength
• Rogue devices
• Intermittent hardware failures. Link Failure The number of times the link on a port has failed. Link-Reset Tx The number of Link-Reset ordered sets transmitted on the port. A port enters the
Link-Reset transmit state to begin the link reset procedure. This is caused by a link timeout or a connection error.
Link-Reset Rx The number of Link-Reset ordered sets received on the port. The Link-Reset is
performed upon receiving a Link-Reset. When a port is receiving Link-Resets, it will begin transmitting idles.
OLS Tx The number of Offline-State ordered sets (OLS) transmitted on the port. A port enters
the Offline-State to perform initialization after a port has been powered on or internally reset. A port also enters Offline-State prior to powering off or performing internal diagnostics. OLSs are normal; however, high counts could indicate problems.
OLS Rx The number of Offline-State ordered sets (OLS) received on the port. A port enters the
Offline-State when it receives the OLS primitive sequence. While in this state, the port transmits the Link Reset (LR) primitive ordered set initiating a Link Reset. OLSs are normal; however, high counts could indicate problems.

Open-CLS Rx The counter for the number of CLS received to OPNs sent. This occurs when the
target device refuses to accept an OPN. If the counter increases, attempts to send data out the port will be affected and perform an ce will begin to d egrade. This ca n be a sign of congestion or a slow device.
Open-CLS Tx The counter for the number of CLS transmitted to OPNs received. This occurs when
the port does not allow a remote device to send data to it, indicating the RX buffers are full or the device is unavailable. Frames in the buffers are being held due to a destination device not servicing frames. Frames then back up the TX queue for the destination device until the switch does not allow the source device to send more frames. This can be a sign of congestion on the destination port. A slow servicing device may need tuning of the data I/O request size.
ABTS Rx The number of ABORT sequences received on the port. ABTSs are responses to the
error condition when a frame or sequence of frames are lost or out of order.
30-10022-01 loop switch user guide 33
The Frame Counts statistic page displays the following information:
Figure 17 Advanced Statistics Frame Counts page
Diagnostic Description
CRC Errors The number of Cyclic Redundancy Check (CRC) errors that are detected in frames
passing through the port since the last switch reset or since the counters were cleared. CRC errors can be caused by the following conditions:
• Connection problems with a remote device
• Link data corruption caused by a high number of Invalid TX words
• Bad cabling or other electromagnetic interference
• Partial SFP insertion Short Frames The number of frames that are shorter than the minimum allowed frame size. Long Frames The number of frames that have exceeded the maximum allowed frame size. Invalid Words The number of invalid 10-bit words received on the port. This is typically caused by a
link corruption such as a code violation (10b/8b decoding), framing error, or a disparity error.

Troubleshooting Device Connections

Problem Recommended Action
SFP installed in one or more ports, but LED is not lit
SFP installed, but only yellow LED is lit
SFP installed with green LED lit, but devices are not communicating
1. Verify that the power cord is firmly seated into switch and is connected to a properly earthed receptacle (outlet).
2. Check the Power LED to ensure that the switch is turned on.
3. Verify that the SFP is firmly seated.
1. Make sure that the device is powered on and operating properly.
2. Unplug the fiber cable from the node and verify that an optical signal is present on the cable receiver lead.
3. Verify that the fiber cable is fully seated at either end. If optical power meter is available, verify the device is transmitting a
signal. If there is no signal present, the device may require rebooting, device drivers may need to be reinstalled, or the HBA or disk controller hardware may require servicing. If a signal is present on both the cable lead and the end node, the HBA or disk controller may require service.
4. Ensure that the device and switch are operational and set to the same speed.
The switch is receiving a valid signal from the device, but no upper level protocols are active.
1. Verify that the proper HBA device drivers are loaded for the appropriate operating system and that the host has been configured to recognize attached disk devices.
2. Improper FC-AL initialization could result from a defective or inoperative adapter card or device. Run adapter diagnostics with a loopback connector to see if the adapter is working properly.
3. Unplug the fiber cable from the end node and verify that an optical signal is present on the cable receiver lead. If no signal is present, the cable’s receiver lead may be bad and the device may be streaming F8 Failure notifications.

Troubleshooting Management Connections

Problem Recommended Action
Serial cable installed, but connection does not appear on terminal
Ethernet cable installed, but Web Manager does not appear
1. Cycle power by reinstalling the power cord.
2. Check the terminal emulation program’s serial port parameters.
3. Replace the serial cable. Make sure it is a null modem cable.
4. Verify the COM port is not already in use.
1. Ensure that a crossover Ethernet cable is used (unless using an Ethernet hub).
2. Make sure the IP address and subnet mask are available and correct. This may require contacting your IT administrator.
3. If going across a router, ensure you have the gateway address entered.
4. Check the communication path between the switch and workstation as follows:
At a command line prompt, type ping DNS or IP (where “DNS or IP” is the switch’s DNS name or IP address) and press If a “Reply from…” or “...is alive...” message can communicate. If a “Request timed out” message out), the devices cannot communicate. Trace the cabling. If needed, reconnect the devices.
