CPU subsystem

The 3534 Model F08 system board is a single-board design with a highly integrated CPU. The Intel

80960VH CPU is a RISC core processor and is the top choice for this platform. It provides over 70% of the functionality for the digital section of the system board. The system uses three types of memory devices: dynamic random access memory (DRAM), Flash File, and Boot Flash. On the Fibre Channel section of the system board, the following three components provide high-speed data transfer:

v The Bloom ASICs v The Serializer/Deserializer (SERDES) v The SFP media. SFP media interfaces support SWL and LWL.

An Intel 80960VH CPU is used for management functions and switch initialization. The CPU runs the Fabric OS and is responsible for switch initialization, configuration, and management. Switching functionality is provided by the ASIC.

The following peripherals are also supported:

v An Ethernet port v A serial port v Three digital thermometers v A real-time clock v General input/output (I/O)

The CPU subsystem is a mixed voltage system that uses 1.8 V, 2.5 V, 3.3 V, and 5 V, depending on the device. The maximum board power consumption is 50 W.

Features

The 3534 Model F08 CPU subsystem includes the following features:

v A 80960VH-100 MHz CPU v An SDRAM controller with parity check at 33 MHz v A peripheral control interconnect (PCI) bus arbiter v Main memory (SDRAM): 32 MB v Flash memory: Dual 8 MB v Boot flash memory: 512 bytes of 8-bit for system start v 10BASE-T or 100BASE-T port for management connection with RJ45 connector v One RS232 port with DB9 connector

Chapter 1. Introduction 3

v Eight light-emitting diodes (LEDs) to indicate the status for each port v Eight LEDs to indicate the link speed for each port v One LED on the front panel to indicate the overall switch status v One LED on the back panel to indicate the overall switch status v Two LEDs for the Ethernet port to indicate the port status and link speed

information

v Three digital thermometers for temperature sensing v One 3.3 V to 1.8 V dc/dc converter for the Bloom ASIC core supply v One Bloom ASIC to support up to eight nonblocking ports v Eight SERDES v One real-time clock with a battery

Embedded processor

The embedded processor is an Intel 80960VH processor with a clock speed of 100 MHz. It contains the following components:

v A high-performance RISC processor core (compatible with the 2109 and 3534

series of switches)

v An integrated EDO memory controller (for DRAM, SRAM, read-only memory

(ROM), and Flash memory)

v A PCI bus interface v A complex programmable logic device (CPLD) for SDRAM control v Two direct memory access (DMA) channels v An I2C interface v General purpose I/O

You access system memory through the local bus. The external CPLD SDRAM device provides SDRAM controller functionality at 33 MHz. It supports parity checking to enhance the data integrity of the system. The CPU communicates with the ASIC and the 10BASE-T or 100BASE-T Ethernet media access controller (MAC) through the PCI interface. An external PCI bus arbiter enables the Ethernet device to be a bus master.

You can also access the RS232 Universal Asynchronous Receiver Transmitter (UART) serial port through the local bus. Other I/O peripherals, such as the real-time clock, the LEDs, the three digital thermometers, and miscellaneous I/O are handled by the I2C bus of the CPU. The CPU is the only I2C bus master in the system. The RS232 port and drivers, Ethernet MAC/PHY, and LEDs are external components to the CPU. An RJ45 connector provides Ethernet connection to external systems. The DB9 RS232 is a ribbon-cable connection through the on-board 10-pin header.

Bus operations

The interface between the embedded processor, the ASIC, and the 10BASE-T or 100BASE-T Ethernet MAC is implemented by using a PCI bus. All PCI devices on the bus are PCI Revision 2.2 compliant. The PCI bus interface operates at 32-bit, up to 33 MHz and has a worldwide even parity bit. A slave-only PCI interface is provided by each ASIC to allow the processor to program various registers, routing tables, and so on within the chip. An external PCI bus arbiter enables the Ethernet device to be a bus master.

The local bus, a 32-bit multiplexed burst bus, provides the interface between the system memory and the I/O. Because the integrated EDO memory controller on the

4 IBM TotalStorage SAN Switch: 3534 Model F08 Installation and User’s Guide

CPU allows only direct control for DRAM, SRAM, ROM, and Flash memory, the external CPLD controller is included to provide SDRAM controller functionality.

The I2C bus provides peripheral I/O control for the LEDs, the thermometers, and general I/O functions. The 80960VH CPU serves as the master on the I2C bus.

The Bloom ASIC is an eight-port Fibre Channel switch controller. A proprietary 10-bit wide SSTL2 bus running at 106.25 MHz is used between the Bloom ASIC and the SERDES.

Memory and memory architecture

The system design uses three types of memory devices:

v DRAM v Flash File v Boot Flash

One on-board SDRAM chips provides up to 32 MB for system memory. One additional SDRAM chip provides data parity. The printed circuit board (PCB) SDRAM footprint is designed to be compatible with 64 MB, 128 MB, and 256 MB devices. An external CPLD device added to the local bus provides control functions for the 80960VH processor.

The system provides 4 MB of on-board redundant Flash File memory for software and data storage. The Boot Flash is an 8-bit Flash device socket that is used only for system start. The Boot Flash device contains a block area for startup code protection. The PLCC32 socket supports 3.3 V Boot Flash memory up to 512 KB.

As with the 2019 series of switches and the 3534 1RU switch, the 3534 Model F08 is based on a central memory architecture. In this scheme, a set of buffers in the central memory is assigned to each port to be used for receipt of frames. As an ASIC port receives and validates a frame, it stores the frame in one of its receive buffers in the central memory and forwards a routing request (a Put message) to the appropriate destination ports. When a destination port is capable of transmitting the frame, it reads the frame contents from central memory and forwards the frame to its transmit interface. It does not wait for the frame to be written in memory, unless the port is busy. After it has removed an entry for a frame from its internal transmit queue in preparation for transmitting a frame, the destination port sends a transmission complete message (a Finish message) to the port that received the frame. This allows the receiving port to reuse the buffer for subsequent frames received.

Central memory is also incorporated into the ASIC. Frames received on the ports in an ASIC are written into the portion of central memory.

The ASIC contains a RAM device plus data path crossbar logic that is used to implement the central memory. Memory blocks are accessed in a time-sliced fashion. The buffer pool can be split into 2112-byte buffers or into 312-byte mini-buffers. If frames that need to be buffered are smaller than the maximum 2112 bytes, using mini-buffers effectively expands the buffer pool and increases the efficiency of memory usage by providing more (but smaller) receive buffers.

Additionally, the Bloom ASIC provides a special memory interface (SMI). The SMI provides the firmware with a mechanism to read and write frame contents to and from the ASIC. It also supports higher throughput transfers. The SMI includes a set of two buffers that are large enough for an entire maximum-sized frame to be

Chapter 1. Introduction 5

transferred in a single operation. Additionally, because there are two buffers available, the firmware can perform a read or write on a frame in one of the buffers while the ASIC streams another frame into the other buffer.

ASIC

The ASIC provides eight Fibre Channel ports that you can use to connect to external node ports (N_ports) (as an F_port) or external loop devices (as an FL_port). You can connect one port (as an E_port) to another 3534 or 2109 series switch. With the fabric upgrade, you might have up to eight E_ports.

Each port can operate at either 1.0625 Gbps or 2.125 Gbps link speeds. The ASIC contains the Fibre Channel interface logic, message and buffer queuing logic, receive buffer memory for the eight on-chip ports, and other support logic.

The Bloom ASIC is a PCI slave to the CPU. The ASIC interfaces through an inter-chip 10-bit SSLT2 bus connection clocked at 106.25 MHz. An 8-channel SERDES is used to support eight ports. The interface between ASIC and SERDES is also a 10-bit SSTL2 bus running at 106.25 MHz. The SERDES converts the 10-bit wide parallel data from the SSTL2 bus into high-speed serial data for the SFP media and vice versa. The SERDES supports single data rate (SDR) or double data rate (DDR) transfer between the SERDES and the SFP media. Implementing the SERDES external to the ASIC reduces the risk of silicon packaging as well as the risk of running 2.125 Gbps signals on a board with a long trace length.

The SFP media interfaces with external devices and enables support for shortwave laser and longwave laser. Two LEDs for each port provide port status and link speed information.

Ports

Control Message Interface: The 3534 Model F08 Control Message Interface (CMI) consists of a set of control signals that are used to pass hardware-level messages between ports. Recipient ports use these control signals to inform transmitting ports when a new frame needs to be added to the output queue of the transmitter. Transmitting ports also use the CMI to inform recipient ports that a frame transmission has been completed. A recipient port is free to reuse a receive buffer when it receives notification that the frame has been transmitted. In the case of multicast, multiple notifications are required to determine when a receive buffer is freed.

The CMI interface for the ASIC is connected inside the ASIC. Each chip time slices its output port to each possible destination chip in the switch. If it has a message to send to a particular destination during the corresponding time slot, the chip uses the time slot to send the message. Otherwise, the output port lines are driven to indicate that no message is present.

The 3534 Model F08 supports the following port types:

v Optical ports v Ethernet port v Serial port

The ASIC in the 3534 Model F08 connects up to eight SFP modules. SFP devices are encased in metal to ensure low emissions and high thermal management. They are hot-swabble and use industry-standard local channel connectors. Each port

6 IBM TotalStorage SAN Switch: 3534 Model F08 Installation and User’s Guide

provides ISL, loop, and fabric (E, F, and FL respectively) type connectivity that the 3534 Model F08 senses automatically. No adminsitration is necessary to identify the port type.

Optical ports

For optical ports, the 3534 Model F08 uses SFP fiber-optic transceivers that convert electrical signals to optical signals (and optical signals to electrical signals). Capable of transmitting at both 1 and 2 Gbps speeds, each SFP fiber-optic transceiver supports 850 nm SWL on multimode fiber-optic cable or 1310 nm LWL on single-mode fiber-optic cable. These miniature optical transceivers provide high port density and deliver twice the port density of standard removable gigabit interface converter (GBIC) transceivers.

Ethernet port

The 3534 Model F08 provides a fully IEEE-compliant 10BASE-T or 100BASE-T Ethernet port for switch management console interface. When a device is connected to the port, both ends negotiate to determine the optimal speed. The Ethernet port uses an RJ45 connector. There are two LEDs for the port. One LED indicates transmit and receive activity and one LED indicates speed (10 Mbps or 100 Mbps). You can configure the Transmission Control Protocol/Internet Protocol (TCP/IP) address for the port from the serial port.

Serial port

An RS232 serial port is provided on the 3534 Model F08. The serial port uses a DB9 connector. The connector is a header pin block on the system board. The parameters of the serial port are fixed at 9600 baud, 8 data bits, no parity, no hardware flow control, 1 start, and 1 stop bit.

Enclosure

You use this connector to configure the internet protocol (IP) address and to recover the factory default settings of the switch should Flash memory contents be lost. The serial port connection should not be used to perform normal administration or maintenance functions. Accessible functions are limited to connecting a terminal to the port to reinitialize the switch defaults, which restores the switch to its factory configuration. This is required to restore the switch passwords to a known state and to allow you to set a specific switch IP address.

The 3534 Model F08 enclosure is designed for you to mount it in a 19-in. rack, with a height of 1 RETMA unit, but you can use it in a tabletop configuration.

The 3534 Model F08 enclosure has forced-air cooling. The fans push the air from the rear chassis intake through the enclosure and exhaust the air through venting holes in the front panel. The SFP media is hot-swappable so that it can be removed and replaced without interrupting the system power.

Other than the SFP replacement, the 3534 Model F08 has no user-serviceable parts.

On the front of the unit, there are two port connections (an RS232 connection and an RJ45 connection). The RJ45 connection provides a 10BASE-T or 100BASE-T Ethernet port for a full system management console interface. The RS232 connection provides a serial port interface for setting the IP address of the switch and for resetting the switch to factory defaults.

The fibre-optic cables, Ethernet cables, ac power input cables, and serial port cables are located on the front of the switch.

Chapter 1. Introduction 7

Power supply

The 3534 Model F08 power supply is universal and capable of functioning worldwide without using voltage jumpers or switches. It meets IEC 61000-4-5 surge voltage requirements and is auto-ranging in terms of accommodating input voltages and line frequencies.

The power supply meets the following requirements:

Specification Value

Outlet Correctly wired and earth-grounded Maximum output 75 watts Maximum system power consumption 50 watts Input voltage 90 – 264Vac Input line frequency 47 – 63 Hz Harmonic distortion Active power factor correction per

IEC1000-3-2

British thermal unit (BTU) rating 60 watts x 3.412 BTU/hr/watts = 204.72

BTU/hr Inrush current 40 amps maximum, cold start at 25°C (77°F) Input line protection Fused in hot line

LEDs

The 3534 Model F08 provides several LEDs to indicate status on the switch. Each of the eight ports has two status indicators. The first LED for the port is a two-color (green and yellow) LED, and indicates the status for the port. Green indicates normal status, and yellow indicates an error. The second LED is a single-color (green) LED and indicates the link speed for the port. Green indicates 2 Gbps. If the green LED is not lit (dark), it indicates 1 Gbps.

A single-color (green) LED is located on the front of the switch and indicates system power-on status. On the back of the switch, there is a two-color (green and yellow) LED driven by an I2C I/O expander that indicates the mode of the unit. Green indicates normal mode, and yellow indicates diagnostic mode. All LEDs are surface mount components with on-board light pipe and are visible externally with full chassis enclosure.

There are two LEDs for the Ethernet port located on the front panel. One LED indicates the transmit and receive activity, and one LED indicates speed (10 Mbps or 100 Mbps).

Software components

The 3534 Model F08 is supported by the Fabric OS version 3.1 or later.

| | | |

Fabric OS is implemented in firmware and manages the operation of the 3534 Model F08. The switch firmware is designed to make a 3534 Model F08 easy to install and use while retaining the flexibility needed to accommodate your requirements. The Fabric OS is made up of two major software components:

v Firmware that initializes and manages the switch hardware v Diagnostics that perform component self-testing algorithms for fault isolation

Fabric Manager

Fabric Manager provides a GUI that allows the administrator to monitor and manage a fabric from a standard workstation. For more information, see the Brocade Fabric Manager User’s Guide.

Extended fabrics

Extended fabrics activation extends SAN fabrics beyond the Fibre Channel standard 10 km, which enables high performance applications over extended distances for storage consolidation, data protection, disaster tolerance, and data sharing.

Remote switch

Remote switch activation extends the distance of the SAN fabric by enabling two Fibre Channel switches to interconnect over an asychronous transfer mode (ATM) wide area network (WAN).

Note: To activate these features, go to the following Web site:

Switch initialization

When you start or restart the switch, the following operations are performed:

1. Early power-on self test (POST) diagnostics are run. POST is run before VxWorks is running.

2. VxWorks is initialized.

3. The hardware is initialized. The system is reset, the internal addresses are assigned to Loom chips, the Ethernet port is initialized, the serial port is initialized, and the front panel is initialized.

4. A full POST is run.

5. The links are initialized. Receiver and transmitter negotiation is run to bring the connected ports online.

6. A fabric exploration is run. This determines whether any ports are connected to other switches. If so, it determines the principal switch.

7. Addresses are assigned. After the principal switch is identified, port addresses are assigned. Each 3534 Model F08 tries to keep the same addresses that it used previously. Previous addresses are stored in the configuration Flash memory.

8. The routing table is constructed. After the addresses are assigned, the unicast routing tables are constructed.

9. Normal node port or node loop port (Nx_port) operation is enabled.

www.ibm.com/storage/key/

10 IBM TotalStorage SAN Switch: 3534 Model F08 Installation and User’s Guide

Routing

The embedded processor maintains two routing tables, one for unicast and one for multicast. The unicast routing tables are constructed during fabric initialization. The multicast tables are initially empty, except for broadcast. After the tables have been constructed, they are loaded into each ASIC.

The unicast tables change if ports or links come online or go offline, or if some other topology changes occur. When new paths become available, the embedded processor can change some routes in order to share the traffic load. The multicast tables change as ports register with the alias server to create, join, or leave a multicast group. Each time a table changes, it must be reloaded into the ASICs.

Service functions

The ASIC interrupts the embedded processor when a frame arrives that has an error (for example, incorrect source ID), when a frame times out, or when a frame arrives for a destination that is not in its routing tables. In the latter case, the frame might be addressed to an illegal destination ID, or it might be addressed to one of the service functions that the embedded processor provides, such as SNMP, name server, or alias server.

SNMP

Simple Network Management Protocol (SNMP) allows network devices to be monitored, controlled, and configured remotely from a network management station running a network manager program.

SNMP agent code in the network device allows management by transferring data that is specified by a management information base (MIB).

The 3534 Model F08 agent supports the following functions:

v SNMPv1 manager v Command-line utilities to access and command the agent v MIB-II system group, interface group, and SNMP group v Fabric-element MIB v IBM-specific MIBs v Standard generic traps v IBM-specific traps

Diagnostics

The 3534 Model F08 supports a set of POSTs, as well as tests that you can run by using Telnet commands. These diagnostics are used during the manufacturing process as well as for fault isolation of the product in your installation.

For more information, see the Brocade Diagnostic and System Error Message Reference.

Diagnostic environment

Most diagnostics are written to run in the VxWorks environment. However, as VxWorks does not run without a working SDRAM, a SDRAM/boot EEPROM test is run as part of the pre-VxWorks startup code to verify that the basic processor-connected memories are functioning properly.

Chapter 1. Introduction 11

Hardware support

Loop-back paths for frame traffic are provided in the hardware for diagnostic purposes. A loop-back path within the ASIC, at the final stages of the Fibre Channel interface, can be used to verify that the internal Fibre Channel port logic is functioning properly, as well as paths between the interface and the central memory. Additionally, the SERIALLINK macro within the ASIC includes a serial data loop-back function that can be enabled through a register in the corresponding ASIC.

Diagnostics are provided to allow traffic to be circulated between two switch ports that are connected with an external cable. This allows the diagnostics to verify the integrity of the final stage of the SERDES interface, as well as the media interface module.

Diagnostic coverage

The POST and diagnostic commands concentrate on the Fibre Channel ports and verify switch functionality of the 3534 Model F08.

Interoperability

This section includes information about interoperability.

Switch interoperability

The 3534 Model F08 supports both 1 Gbps and 2 Gbps transmit and receive rates with auto-negotiation. The actual data signaling rate that is used on a port is automatically sensed and is set to the rate that is supported by a device or devices that are attached to the port. The 3534 Model F08 has been tested and is compliant with the current FC standards. The 3534 Model F08 is compatible with most current-generation switches N_ports, NL_ports, and E_ports, as well as host adapters, Redundant Array of Independent Disks (RAIDs) storage devices, hubs, and Fibre-SCSI bridge devices, including the 3534 and 2109 series of switches.

Implementation in existing environments

Because the 3534 Model F08 has a compatible 1 Gbps auto-negotiated signaling rate on each port, you can use it as a replacement for current 3534 and 2109 series switches. As newer technology is added to existing systems that support 2 Gbps signaling, the ports can accept these devices and interoperate with existing 1 Gbps devices. If the 3534 Model F08 is connected to a third-party device but is unable to negotiate the signaling rate, the 3534 Model F08 allows you to manually set the speed of each port through the management interfaces.

Heterogeneous interswitch operations

Fabric OS version 3.1 or later supports interoperability for the following functions: v Basic switch functions

– Link initialization – Principal switch selection – Routing Fibre Channel shortest path first (FSPF)

v Basic services

– Simple name service – State change notification – WWN zoning (typically referred to as soft zoning or name server zoning)

12 IBM TotalStorage SAN Switch: 3534 Model F08 Installation and User’s Guide

The following facilities are switch-based facilities and will continue to function on any 3534 switch:

v SNMP facilities v Simple QuickLoops with no zoning v Translative mode (private target support on fabrics) v Trunking (only functions between two IBM switches) v Enhanced performance metrics

The following facilities are IBM value-added facilities that are not supported in a multi-vendor fabric. Use of these facilities causes the Fabric to segment.

v QuickLoop zones v QuickLoop Fabric assist mode v Port, protocol, or LUN zoning

IBM is not aware of any areas of noncompliance with any ratified standards at this time.

Host bus adapter interoperability

For a list of host bus adapters (HBAs) that have been tested and approved for use with the 3534 Model F08, go to the following Web site: www.storage.ibm.com/ibmsan/products/2109/san_switch_solu.html

Operating system support

Fabric OS versions 2.x and 3.x have no specific OS dependencies. The Fabric OS in the switches allows for any Fibre Channel-compliant device to attach to the switches as long as it conforms to the standards for device login, name service, and related Fibre Channel features. Regardless of the operating environment, proper interface to the fabric requires a Fibre Channel HBA with a standards-compliant driver.

Reliability

The 3534 Model F08 provides the following features to ensure reliability:

v POST v Error detection and fault isolation (internal and external CRC checking, parity

checking, checksum, and illegal address checking)

v Continuous monitoring of environmental components (fan status and

temperature)

v DC power in proper range monitoring v Low component count

Because buffering is integrated into the ASICs in the 3534 Model F08, you do not need external SRAM chips on the system board.

The 3534 Model F08 utilizes a highly integrated 80960VH processor that incorporates a memory controller, PCI bus arbiter, and I2C controller in the processor chip, reducing the parts count for the processor functions. Because a single system board contains all circuitry, the 3534 Model F08 requires no interboard connections.

Chapter 1. Introduction 13

How to manage the 3534 Model F08

For system debugging and performance analysis, you can manage the 3534 Model F08 using either the in-band or the out-of-band management method. In-band uses Fibre Channel protocol and out-of-band connects to the Ethernet port. You can monitor the following attributes:

v Fabric topology v Port status v Physical status

Note: The switch automatically performs power-on self-test (POST) diagnostics

each time you turn it on and records any detected errors in the error log. For more information about POST, see “Interpreting POST” on page 28.

Table 2 shows the management interfaces that are compatible with the 3534 Model F08 and whether you can use these interfaces in-band, out-of-band, or both.

Chapter 2. Installing and configuring the 3534 Model F08

You can install the 3534 Model F08 as a stand-alone unit or in a rack that meets Electronic Industries Association (EIA) standards.

This chapter describes how to install and configure the 3534 Model F08 and includes the following information:

v Installation and safety considerations v Installing the 3534 Model F08 as a stand-alone unit v Installing the 3534 Model F08 in an EIA rack v Configuring, connecting, and accessing the 3534 Model F08

For information about the features of the 3534 Model F08 and what is included in each 3534 Model F08 package, see “Overview of the 3534 Model F08” on page 1.

Installation and safety considerations

You must follow these guidelines when you install the switch: v Verify that the supply circuit, line fusing, and wire size that will be used are

adequate according to the electrical rating on the switch nameplate.

v The switch is designed for an internet protocol (IT) power system with

phase-to-phase 230 V. The power supply might still be energized, even if internal power supply over current protection devices have opened.

DANGER

When powering the unit with a line-to-line connection greater than 200 V ac, a potential shock hazard can arise during a fault condition. Therefore, double-pole protection is required. (5)

v Ensure the ambient air temperature does not exceed 40°C (104°F). This is

particularly important if the switch is to be installed in a closed or multirack assembly.

v Ensure the volume of air flow available to the switch is at least 300 cubic feet per

minute, and that the front and rear air vents are not blocked.

If you are installing the switch in a rack: v Ensure the ambient air temperature does not exceed 40°C (104°F). This is

particularly important if the switch is to be installed in a closed or multirack assembly.

v Ensure the volume of air flow available to the switch is at least 300 cubic feet per

minute, and that the front and rear air vents are not blocked.

v The switch requires a rack space that is 1 unit high, 48.26 cm (19 in.) wide, and

60.96 cm (24 in.) deep.

v Verify that all equipment installed in the rack has a reliable branch circuit ground

connection. Do not rely on a connection to a branch circuit, such as a power strip.

v Verify that the additional weight of the switch does not unbalance the rack or

exceed the weight limits of the rack.

v Secure the rack to ensure stability in the event of an earthquake.

Chapter 3. Operating the 3534 Model F08

This chapter describes how to operate the 3534 Model F08 and includes the following information:

v Turning the 3534 Model F08 on and off v Interpreting LED activity v Interpreting POST v Running diagnostic tests

Turning the 3534 Model F08 on and off

To turn on the 3534 Model F08, plug it into a power outlet. The power supply does not have an ac switch. To turn the switch off, unplug it from the power outlet.

Note: Unplugging the switch triggers a system reset. When the switch is plugged

in, all devices are returned to the initial state and the switch runs a POST. For information about the POST, see “Interpreting POST” on page 28.

Interpreting LED activity

You can determine system activity and status by monitoring the activity of the LEDs on the switch.

Note: The LEDs might flash yellow during diagnostic tests and green, orange, or

yellow during a POST. This is normal. This does not indicate that there is a problem unless the LEDs do not return to a normal pattern after the POST is complete.

The 3534 Model F08 has the following LEDs:

Port Status LED

These LEDs indicate the status of each port. There are eight port status LEDs that are located above and to the left of each port on the front panel.

Port Speed LED

These LEDs indicate the speed of each port. There are eight port speed LEDs that are located above and to the right of each port on the front panel.

Switch Status LED

These LEDs indicate whether the switch is on and has successfully started. There are two switch status LEDs, one on the front panel and one on the back.

Ethernet port LED

These LEDs indicate the speed and status of the Ethernet link. There are two Ethernet port LEDs that are located to the left of the Ethernet port on the right side of the front panel.

Errors might be listed in the error log. Refer to the

Brocade Diagnostic and System Error Message Reference for more

information.

SJ000354

Interpreting POST

The 3534 Model F08 automatically performs a POST when the switch is plugged in, restarted, or the system is reset. A POST includes a number of diagnostic tests. You can monitor test results through the LED activity, error log, Telnet command, from a terminal screen, and so on.

A POST completes in 4.5 minutes. A slightly longer version of the memory test is performed after cold starts. A cold start occurs after a complete power cycle, when

28 IBM TotalStorage SAN Switch: 3534 Model F08 Installation and User’s Guide

the switch is unplugged, then plugged back in. A warm start is any other type of startup, such as an operating system restart or switch panic.

A POST consists of the following steps:

1. Preliminary POST diagnostics are run.

2. The operating system is initialized.

3. The hardware is initialized.

4. Diagnostic tests are run on a number of the following functions:

v Internal connections and circuitry v Port functionality v Ability to send and receive frames v Ability to implement QuickLoop functionality v All aspects of memory, parity, statistics counters, and correct serialization

5. A universal port configuration is performed.

6. The links are initialized.

7. The fabric is analyzed. If ports are connected to other fabric elements, the principal switch in the fabric is identified.

8. The port addresses are assigned. The switch attempts to keep any previously assigned port addresses.

9. The unicast routing tables are constructed.

10. The port is enabled. To determine whether a POST has completed without errors, verify that all LEDs

return to a normal state after the POST is complete. If one or more LEDs continue to flash, see “Interpreting LED activity” on page 25. Verify that the flashing is not due to the switch being configured to beacon.

Note: The switchBeacon command sets the switch beaconing mode on or off if

the operand is 1 or 0 respectively. When beaconing mode is turned on, the port LEDs flash orange in a running pattern from port 0 - port 7, port 7 - port 0, and then back to port 7 again.

For more information about beaconing, see the Brocade Fabric OS Procedures Guide.

Note: When POST completes, verify that the switch prompt displays on a computer

terminal that is connected to the switch. If the prompt does not display, press the Enter key. If the prompt still does not display, contact IBM.

If errors are detected during a POST, error messages are written to the system error log. You can view this error log by using the errShow command. For information about error messages, see the Brocade Diagnostic and System Error Message Reference.

Running diagnostic tests

Diagnostic tests are provided to help you to identify problems in the hardware and the firmware. The diagnostic tests include tests of internal connections and circuitry, fixed media, and any SFP modules and fiber-optic cables that are in use. You can run the tests either using Telnet or through a terminal that is set up for a serial connection to the switch. Some tests require that you connect the ports with

Chapter 3. Operating the 3534 Model F08 29

external cables. This enables the diagnostics to verify the serializer or deserializer interface, as well as the attached SFP and cable.

All diagnostic tests are run at link speeds of 1 Gbps and 2 Gbps. As a result, the transmit and receive speed of the links can be temporarily locked at one speed or the other while the diagnostic tests are running. For information about the specific diagnostic tests and how to run them, see the Brocade Diagnostic and System Error Message Reference.

Appendix B. Standards and protocol compliance

IBM is committed to providing products that comply with industry standards and protocols.

Standards

The 3534 Model F08 is compliant with the following standards: v Fibre Channel ANSI Specifications

– FC-PH, version 4.3 (Fibre Channel Physical) – FC-PH-2, version 7.4 (Fibre Channel Physical, Enhanced) for Multicast and

Broadcast functions

– FC-PH-3, version 9.4 – FC-SW-2, version 4.4 (Fibre Channel Switched Fabric) – FC-FG Revision 3.5 (Fabric Generic Requirements) – FC-AL, version 4.5 (Arbitrated Loop) – FC-AL-2, version 5.7 (Arbitrated Loop Extensions) – FC-FLA, version 2.7 (Fabric Loop Attach) – FC-GS-2, version 5.3 (Generic Services) – FC-GS-3, version 6.42 or later (Generic Services) – FC-PLDA, version 2.1 (Private Loop Direct Attach) – FC-Tape Fibre Channel Tape (FC-Tape) – FCP-2Rev4 (Fibre Channel Protocol) – FC-FS Revision 0.2 or later – FC-IP

v SCSI Enclosure Services, Rev 8a v EA/TIA RS-232 Serial Port specification v Gigabit Interface Converter Definition Document, Sun, and so on v IEEE 802.3 for Ethernet

Protocol compliance

The 3534 Model F08 complies with the following standards and protocols.

Support for Fibre Channel ports

All ports on the 3534 Model F08 are universal ports and support F_port (point-to-point), FL_port (loop), and E_port (switch-to-switch) port connections.

Fibre Channel class operation

The 3534 Model F08 supports Fibre Channel Class 2, Class 3, and Class F operations on all ports.

Auto-configuration

All ports support E_ports to allow for cascading switches to form larger fabrics. E_ports are auto-configuring. Linking ports from any two switches automatically configures an E_port connection to form the fabric. The 3534 Model F08 supports a trunking option that binds up to four ports together as a high-performance trunk group. In this trunking configuration, interswitch data transfers can occur at an

aggregate rate of 800 MBps in both directions. The trunk group is automatically configured on the ports of the switch as the links between the switches are connected.

In-order delivery

The 3534 Model F08 guarantees in-order delivery of frames between source F_port or FL_port and destination F_port or FL_ port. In-order delivery is supported across any arbitrary switch configurations or fabric topologies.

Flexibility of fabric topology and operation

The 3534 Model F08 implements the FSPF routing protocol as specified in the T11 FC-SW-2 standard. Fabric topology and operation are automatically adjusted and dynamically distributed to the fabric as new switches and links are added to the fabric. This is completed with no operator intervention. When a link is added or removed, the routes are recalculated. The switch adopts a minimal disruption algorithm to minimize the impact of the route recalculation. To minimize disruption, the switch only reroutes traffic due to a new shortest path (if one has been established) or if new load sharing is required.

Fibre Channel simple name service

Fabric OS includes support for the Fibre Channel simple name service as specified in FC-GS-3 version 6.42 or the latest published standard.

Fibre Channel state change notification service

Fabric OS supports the Fibre Channel state change notification service as specified in FC-GS-3 version 6.42 or the latest published standard.

Fibre Channel alias and multicast services

Fabric OS supports the alias and multicast services as specified in FC-GS-3 version

6.42 or the latest published standard.

Support for Fibre Channel protocol

The 3534 Model F08 supports the FCP-2Rev4 standard.

Support for FC-IP

Fabric OS supports FC-IP (as defined by IETF), including the address resolution protocol (ARP) service for IP nodes that are connected to the switch.
