1 Introduction 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 memory. 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.
Features The 30-10022-01 loop switch incorporates the following features: • High Performance Fibre Channel Switching: • 2Gb/s or 1Gb/s auto-detection per port • 12-port design with embedded SerDes • Multiple simultaneous conversations between ports • Traffic routed directly to destination ports • Fairness and prioritization ensure that all devices have guaranteed access, or explicitly have prioritized access over other devices in a system • Automatic port configuration simplifies configuration and setup pro
2 Switch Installation 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 shipping. Report any sign of damage to the appropriate shipping agency. 2.

• 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.
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 devices. 2. Insert the plug end of the switch’s power cord to a properly grounded power 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.

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.
9. Type save and press ENTER. 10. Type root reset and press ENTER. 11. Type y and press ENTER to reset the switch. 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.

Viewing Port Information The Port Information page displays the ports, their current health, the AL_PAs currently assigned to each port, and the utilization for each port. Port utilization measures the amount of traffic passing through a port over a period of time. For example, if an initiator is transmitting data to a target, the initiator port displays a transmit (Tx) port utilization value (%) while the target port displays a receive (Rx) port utilization value.
Configuring Port Settings The Port Configuration page displays the ports, their current health status, their current operating speed, and SFP serial identification information. To view the Port Configuration page, click Port Configuration. Figure 12 Port Configuration page Field Description Port Displays the current health of the port. See “Port Utilization and Health” on page 20 for additional information on port health. Enabled Indicates if the port is enabled. The default setting is “Yes”.
1. Click Port Configuration. 2. Select the specific port’s desired speed from the drop-down menu. Setting Description 1 Gb/s Set port speed to 1.0625 Gb/s. 2 Gb/s Set port speed to 2.125 Gb/s. 4 Gb/s Set port speed to 4.25 Gb/s (not supported) Auto Automatically detect and set port speed. 3. Click Submit.
Title Description Force Reset A single-instance operation that places a port in bypass mode and then immediately sets the port to auto-detect to re-insert the port. This feature may be used to diagnose device problems when a device is locked up or experiencing a high number of failures on a port. Clearing Insertion Counters To clear the counters: 1. Click Clear Insertion Counters. A message box is displayed confirming the request. 2. Click OK to clear the insertion counters.
Viewing Advanced Statistics This page displays information that may be used for the advanced troubleshooting of switch-related issues. To view the advanced statistics, click Advanced Statistics. The Advanced Statistics page appears. Figure 14 Advanced Statistics page The Advanced Statistics page displays the following information: Diagnostic Description Low-level Link Low-level FC-1 traffic information. High-level Link High-level FC-1 traffic information.
The Low-level link statistic page displays the following information: Figure 15 Advanced Statistics Low-level Link page 32 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.
The High-level link statistic page displays the following information: Figure 16 Advanced Statistics High-level Link page Diagnostic Description 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 performance will begin to degrade. This can be a sign of congestion or a slow device.
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.
Figure 18 Advanced Statistics Class 2 Traffic page Diagnostic Description Frames Rx The number of frames received for a particular class. For the All Traffic statistic page, this is the total number of frames received from all classes. Frames Tx The number of frames transmitted for a particular class. For the All Traffic statistic page, this is the total number of frames transmitted from all classes. K-octets Rx The number of Kilo-octets received for a particular class.
Managing Firmware The Firmware page displays the current and alternate firmware versions, enables users to select which firmware version to run the next time the switch is reset, and provides a means to load new firmware on the switch. To check for new firmware on the Emulex Web site, click Help. To view the firmware, click Firmware. The Firmware page is displayed. Figure 19 Firmware page Loading New Firmware To load new firmware on the switch: 1.
Configuring Date and Time Settings The Switch Date and Time page displays the switch’s current date and time.

The Change Password page is displayed. Figure 21 Change Password page 2.
4 Technical Reference Troubleshooting Device Connections Problem Recommended Action SFP installed in one or more ports, but LED is not lit 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. SFP installed, but only yellow LED is lit 1. Make sure that the device is powered on and operating properly. 2.
Port Bypass Conditions and Recovery 40 Operational Condition Recovery Rx_los is asserted by an SFP/GBIC The port stays bypassed until rx_los is de-asserted. At that time, the port insertion will be automatically retried. The port continues to stay bypassed until the port can pass the port insertion criteria. Tx_fault is asserted by an SFP/GBIC The port stays bypassed until tx_fault is de-asserted. At that time, the port insertion will be automatically retried.
