network and the number of users increases continually.

The switch features include:

• Up to a 16-to-1 reduction in networking cables and connections, concentration of sixteen Gigabit

Ethernet server ports down to as little as one Gigabit Ethernet port. This switch has the unique feature to provide both one Gigabit and ten Gigabit ports to the network, allowing the user the ultimate in network flexibility

• Fully supported on the HP c-Class BladeSystem server blade enclosure and infrastructure compatible

with any combination of HP c-Class BladeSystem server blades

• Ability to replace an existing switch without having to power down the server blades or the server

blade enclosure

• Pre-configured for immediate use with the HP c-Class BladeSystem server blade enclosure

• System security including SSH, SCP, 255 port-based IEEE 802.1Q tagged VLANs per switch,

RADIUS user authentication and authorization, or TACACS+ AAA

• An extensive list of industry standard protocol support, compatible with widely-used networking

components

Introduction 6

• 9K jumbo frames that improve performance by increasing application throughput and decreasing

server processor utilization

• Robust configuration and management from any switch port using the included browser-based and

scriptable command line user interfaces.

• Support for Telnet, SNMP, SCP, FTP, and TFTP file transfer, human read/write configuration file,

XModem, and an extensive list of MIB objects further enhance the management capabilities

• Fully redundant end-to-end architecture maximizing server availability from the network

• Support for IGMP snooping for multicasting

• Support for UFD for network path resiliency. It works in conjunction with NIC teaming functionality

that is supported on the blade servers. This feature tracks the link state on uplink ports. When an uplink port goes down or is in STP blocking state, this feature will enable the switch to auto disable the downlinks which are connected to the blade server NICs. This enables NIC teaming software to detect link failure on the primary NIC port and fail over to the secondary NIC in the team. As a result, the secondary path is enabled for continued blade server access.

When used in conjunction with UFD, NIC teams on the blade server must be configured for switch redundancy. That is, the team will span ports on both Switch 1 and Switch 2. See the HP network

adapter teaming: load balancing in ProLiant servers running Microsoft Windows operating systems

white paper for additional information. To locate this white paper:

a. Go to the HP website (http://www.hp.com/support). b. Enter "nic" in the product search box. c. A product list displays. Select one of the NIC products. d. Select the "Manuals" link to display the documentation list. This white paper will be under the

"White papers" category.

• RMON feature, which allows network devices to exchange network monitoring data. RMON

performs these major functions:

o Gathers cumulative statistics for Ethernet interfaces o Tracks a history of statistics for Ethernet interfaces o Creates and triggers alarms for user-defined events

• An administrator can define end user accounts that permit limited access to the switch. The switch

requires username/password authentication for end users.

• Fast Uplink Convergence that enables the switch to quickly recover from the failure of the primary

link or trunk group in a Layer 2 network using Spanning Tree Protocol.

• Support for SSH version 2. SSH is a protocol that enables remote administrators to log securely into

the switch over a network to execute management commands.

• Switch software provides SNMP support for access through any network management software, such

as HP OpenView.

• Support for HTTP software upgrade using the BBI. FTP or TFTP server is not required to perform a

software upgrade.

• Port Fast Forwarding that allows a port that participates in Spanning Tree to bypass the Listening and

Learning states and enter directly into the Forwarding state.

• Allows secure browser access (HTTPS) to management functions

Introduction 7

Switch redundancy

In a dual switch configuration, the switches offer several redundancy and failover features. With these features, the network configuration is designed to allow for continued network access to each server blade in case of a component or link failure. The switch redundancy and failover features include:

• Up to eight separate switches per one HP c-Class BladeSystem server blade enclosure

• Up to four, one Gigabit Ethernet uplink ports and three, ten Gigabit Ethernet uplink ports (ports 19-

21), per switch, for designing fully meshed uplink paths to the network backbone

• Server networking connections routed to each of the separate switches for redundant paths to

tolerate a switch or port malfunction

• Redundant data path ten Gigabit Ethernet cross connection between switches

• STP support that eliminates potential problems caused by redundant networking paths and provides

for failover with a secondary path in case of primary path failure; supports IEEE 802.1D Spanning Tree Protocol and is compatible with Cisco configured as untagged or configured to use 802.1q tagging. The switch also supports IEEE 802.1s MSTP and IEEE 802.1w RSTP.

• Redundant power supplies and redundant cooling fans within the server blade enclosure

PVST+ and Cisco PVST, when the other device is

• Redundant firmware images and configuration settings on switch flash memory

• Redundant, configurable DNS clients, syslog servers, gateways, and community strings and SNMP

trap manager hosts

Configuration and management

The switch provides these configuration and management interfaces and tools:

• A scriptable CLI allows local, Telnet, or SSH access.

• An iSCLI that is software selectable.

• A BBI allows remote access using a Web browser such as Microsoft® Internet Explorer or Netscape

Navigator.

• SNMP manageability and monitoring are supported.

• The switch functionality allows uploading and downloading of switch configurations through TFTP

and SCP, thus allowing the rapid deployment of multiple server blade systems, and providing robust backup and restore capabilities.

• NTP is supported, allowing the switch to display and record the accurate date and time as provided

by an NTP server.

• Two firmware images, either of which can be selected to be the current runtime image, can be held

in memory.

• RADIUS provides support for user authentication and authorization.

• TACACS+ provides support for Cisco TACACS+ server compatible authentication, authorization,

and accounting.

• Ability to set NVRAM diagnostic flags

Switch architecture

The HP c-Class BladeSystem provides Ethernet switching technology for network cable reduction. The switch does not affect or determine NIC enumeration and the associated mapping of NIC interfaces

to switch ports. The numbering of the NICs on the server (for example, NIC 1, NIC 2, NIC 3) is

Port Mapping

Dual switches

determined by the server type, the server operating system, and what NICs are enabled on the server.

For detailed port mapping information, see the HP BladeSystem enclosure installation poster or the HP BladeSystem enclosure setup and installation guide on the HP website (http://www.hp.com/go/bladesystem/documentation

In a dual switch configuration, two switches in the server blade enclosure provide switch redundancy and redundant paths to the network ports on the server blades. Each switch has four, one Gigabit and three,

Introduction 9

ten Gigabit external Ethernet ports and sixteen internal Gigabit Ethernet ports providing connectivity to the blade servers within the enclosure.

Redundant crosslinks

In a dual switch configuration, the two switches are connected through a single ten gigabit crosslink. This crosslink provides throughput of ten Gb/s for traffic between the switches.

This crosslink is disabled by default. This crosslink must be enabled for use.

Redundant paths to server bays

In a dual switch configuration, redundant Ethernet signals from each blade server are routed through the enclosure backplane to separate switches within the enclosure. This configuration provides redundant paths to each server bay.

Redundant Ethernet signals from each blade server are routed through the enclosure backplane to separate switches within the enclosure. However, specific switch port to server mapping varies depending on which type of server blade is installed.

On a heavily used system, using a single uplink port for 32 Ethernet signals causes a traffic bottleneck. For optimum performance, HP recommends using at least one uplink port per switch.

Supported technologies

Layer 2 switching

The switch uses Gigabit Layer 2 switching technology. Layer 2 refers to the Data Link layer of the OSI model, which is concerned with moving data packets across a network by enforcing CSMA/CD. This layer performs:

• Ethernet packet framing

• MAC addressing

• Physical medium transmission error detection

• Medium allocation (collision avoidance)

• Contention resolution (collision handling)

Layer 2 switching technology allows the switch to look into data packets and redirect them based on the destination MAC address. This reduces traffic congestion on the network because packets, instead of being transmitted to all ports, are transmitted to the destination port only.

Layer 3 switching

In addition to Layer 2 features, the switch also supports Layer 3 switching. Layer 3 switching features include:

• IP forwarding

• Static routing

• Dynamic routing based on RIP V1/V2 or OSPF protocols

Introduction 10

• High availability VRRP

Layer 3 switching provides more power, flexibility, and security capabilities to network administrators. Network traffic is managed much more efficiently and broadcast traffic between servers remains within the enclosure. Security features provide added protection for switch configuration data, while packet filtering helps secure and segment sensitive traffic or network access.

IEEE 802.1 Q-based VLAN

The switch provides support for a total of 1000 IEEE 802.1Q VLANs for server grouping and isolation. A VLAN is a network segment configured according to a logical scheme rather than a physical layout. VLANs are used to combine any collection of LAN segments into an autonomous user group that appears as a single LAN.

VLANs also logically segment the physical network into different broadcast domains so that packets are forwarded only between ports within the VLAN. This technology enhances performance by conserving bandwidth and improves security by limiting traffic to specific domains. For example, isolate the server blade iLO ports from the rest of the NICs. The iLO ports on Switch 2 are assigned to their own VLAN and go to a dedicated uplink or share an uplink using VLAN tagging.

IMPORTANT: The greater the number of VLANs, the greater the switch CPU utilization. For

maximum switch performance, HP recommends being judicious when configuring the number of VLANs.

NOTE: VLAN 4095 is reserved for future functionality.

Spanning Tree Protocol

The switch supports IEEE 802.1D STP, which allows the blocking of links that form loops between switches in a network. When multiple links between switches are detected, a primary link is established. Duplicated links are blocked from use and become standby links. If the primary link fails, the standby link is activated.

In addition, the switch provides a spanning tree domain per VLAN. The switch is compatible with Cisco PVST+ and Cisco PVST, when the other device is configured as untagged or configured to use 802.1q tagging. Thirty-two spanning tree domains are supported per switch.

NOTE: STP 32 is reserved for future functionality.

The switch also provides IEEE 802.1s-based MSTP and IEEE 802.1w-based RSTP.

SNMP

The switch is configured and monitored remotely from an SNMP-based network management station. The switch supports industry-standard SNMP MIBs and proprietary HP enterprise switch MIBs for fault detection and monitoring of switch functionality. In addition, the switch supports various environmental traps such as temperature and fan failure traps.

To secure the management interface, the switch administrator configures community strings with two levels of access: Read and Read/Write. Access to the switch is also restricted to only management stations that

Introduction 11

are members of a specific IP network. This is achieved by configuring the address/mask of that specific network as a restricted management network address/mask.

Port mirroring

The switch allows mirroring of one or multiple ports (source ports) to another port (destination port) for network monitoring and troubleshooting purposes. This technology offers a way for network packet analyzers to view the traffic moving through the switch by providing a copy of the traffic that is currently being passed through any other port. The packets are sent to a network packet analyzer or other monitoring device attached to the mirror port.

Port trunking and load balancing

The switch supports EtherChannel compatible IEEE 802.3ad (without LACP) port trunking allowing several ports to be grouped together and act as a single logical link called a trunk. This feature provides a bandwidth that is a multiple of the bandwidth of a single link. It also improves reliability since load balancing is automatically applied to the ports in the trunked group. A link failure within the group causes the network traffic to be directed to the remaining links in the group.

TFTP support

TFTP support allows the switch firmware to be upgraded by downloading a new firmware file from a TFTP server to the switch. Firmware images of the switch are also uploaded to a TFTP server, a configuration file is downloaded into a switch from a TFTP server, and configuration settings are saved to the TFTP server.

Store and forward switching scheme

The switch provides a store and forward switching scheme that allows each packet to be buffered (stored) before it is forwarded to its destination. While this method creates latency, it improves reliability in a heavily used switch. Packets that cannot be forwarded are saved immediately, rather than dropped, so that packets behind them are less likely to be dropped in periods of heavy usage.

BOOTP

By default, the switch is configured to obtain an IP address from a BOOTP server during the boot process. The IP settings are also manually configured by means of the serial interface. The IP settings are configurable from the browser-based interface, but because the connection is based on an IP address for these interfaces, users will have to reconnect with the newly assigned IP address.

NTP

The switch maintains the current date and time. This information displays on the management interfaces and is used to record the date and time of switch events. Current date and time information are manually set on the switch or are obtained through NTP. NTP allows the switch to send a request to a primary NTP server in each polling period asking for GMT.

Introduction 12

RADIUS

The switch supports the RADIUS method to authenticate and authorize remote administrators for managing the switch. This method is based on a client/server model. The RAS, the switch, is a client to the back-end database server. A remote user (the remote administrator) interacts only with the RAS, not the back-end server and database.

RADIUS authentication consists of:

• A protocol with a frame format that utilizes UDP over IP, based on RFC 2138 and 2866

• A centralized server that stores all the user authorization information

• A client, in this case, the switch

The switch, acting as the RADIUS client, communicates to the RADIUS server to authenticate and authorize a remote administrator using the protocol definitions specified in RFC 2138 and 2866. Transactions between the client and the RADIUS server are authenticated using a shared key that is not sent over the network. In addition, the remote administrator passwords are sent encrypted between the RADIUS client (the switch) and the back-end RADIUS server.

The benefits of using RADIUS are:

• Authentication of remote administrators

• Identification of the administrator using name/password

• Authorization of remote administrators

• Determination of the permitted actions and customizing service for individual administrators

TACACS+

The switch supports the TACACS+ method to authenticate, authorize, and account for remote administrators managing the switch. This method is based on a client/server model. The switch is a client to the back-end TACACS+ AAA server. A remote user (the remote administrator) interacts only with the client, and not with the back end AAA server.

The TACACS+ AAA method consists of:

• A protocol with a frame format that utilizes TCP over IP

• A centralized AAA server that stores all the user authentication, authorization, and accounting (of

usage) information

• A NAS or client (in this case, the switch)

The switch, acting as the TACACS+ client or NAS, communicates to the TACACS+ server to authenticate, authorize, and account for user access. Transactions between the client and the TACACS+ server are authenticated using a shared key that is not sent over the network. In addition, the remote administrator passwords are sent encrypted between the TACACS+ client (the switch) and the back-end TACACS+ server.

The switch supports:

• Only standard ASCII inbound login authentication. PAP, CHAP, or ARAP login methods are not

supported. One-time password authentication is also not supported.

• Authorization privilege levels of only 0, 3, and 6. These map to management levels of user, oper,

and admin, respectively.

Introduction 13

• The accounting attributes of protocol, start_time, stop_time, and elapsed_time. For BBI users,

accounting stop records are only sent if the user presses the QUIT button.

SSH and SCP

SSH and SCP use secure tunnels to encrypt and secure messages between a remote administrator and the switch. Telnet does not provide this level of security. The Telnet method of managing a switch does not provide a secure connection.

SSH is a protocol that enables remote administrators to log securely into the switch over a network to execute management commands.

SCP is used to copy files securely from one machine to another. SCP uses SSH for encryption of data on the network. On a switch, SCP is used to download and upload the switch configuration via secure channels.

XModem

The switch supports XModem for transferring files during direct dial-up communications. XModem sends blocks of data in 128-byte blocks, and includes an error-detection system called a checksum. When the data is received, the error detection system ensures that the entire message reached its destination. If not, the receiving computer sends a request for retransmission of the data.

IGMP Snooping

The switch supports IGMP Snooping for multicasting. Version 1-, Version 2-, and Version 3-based IGMP Snooping are supported. In addition, auto detection of the multicast router port and manual configuration of the multicast router port is supported. For efficient multicast traffic management, the IGMP Filtering option is supported.

Jumbo frames

By default, the switch supports jumbo frames up to 9216 bytes, which help reduce server CPU utilization and increase application throughput. No configuration is required. The switch does not fragment frames as they exit, or assemble packets into jumbo frames as they enter the switch.

Auto-MDI/MDIX

The switch RJ-45 Ethernet ports are MDI/MDI crossover capable. MDI/MDIX is a type of Ethernet port connection using twisted pair cabling. The MDI is the component of the MAU that provides the physical and electrical connection to the cabling medium. An MDIX is a version of MDI that enables connection between like devices. MDI ports connect to MDIX ports via straight-through twisted pair cabling whereas both MDI-to-MDI and MDIX-to-MDIX connections use crossover twisted pair cabling. The switch has the capability to automatically detect the cable selection/type, making the distinction between a straightthrough cable and a crossover cable unimportant.

Auto-negotiation of duplex mode and speed on 1 Gigabit ports

Auto-negotiation of duplex mode and speed are configured on the switch. Network adapters that support multiple data speeds, such as Fast Ethernet and Gigabit Ethernet, choose the speed at which they run

Introduction 14

through a procedure called auto-negotiation. Auto-negotiation involves probing the capability of the network using low-level signaling techniques to select compatible Ethernet speeds. Auto-negotiation was originally developed to make the migration from traditional Ethernet to Fast Ethernet products easier.

Redundant images in firmware

The switch stores up to two different software images, called image1 and image2, as well as boot software, called boot. When downloading new software, the ability to specify where it is to be placed (into image1, image2, or boot) is activated.

For example, if the active image is currently loaded into image1, load the new image software into image2. This allows a test of the new software and the option to revert back to the original image stored in image1, if needed.

CAUTION: Unlike the firmware that has two images, there is only one image of boot

supported. Upgrading the boot image replaces the original boot image.

Preparing for installation

IMPORTANT: Before installing the switch, make a record of the MAC address (printed on the

MAC address label attached to the switch). This address is needed when configuring the switch.

Planning the switch configuration

The switch ships with a default configuration in which all downlink and uplink ports are enabled and assigned a default VLAN with a VID equal to 1. This default configuration simplifies the initial setup by allowing use of a single uplink cable (from any external Ethernet connector) to connect the server blade enclosure to the network. Assess the particular server environment to determine any requirements for other considerations.

The switch does not affect or determine NIC numeration and the associated mapping of NIC interfaces to switch ports. The numbering of the NICs on the server (for example, NIC 1, NIC 2, NIC 3) is determined by the server type, the server operating system, and which NICs are enabled on the server.

NOTE: Port 18 is reserved for connection to the Onboard Administrator module for switch

management. This allows a user to enable the functionality of future firmware upgrade

The Onboard Administrator module controls all port enabling. Enabling is based on matching ports between the server and the interconnect bay. Before power up, the Onboard Administrator module verifies that the server NIC option matches the switch bay that is selected and enables all ports for the NICs installed.

releases.

Default settings

When planning the configuration, consider the default settings for these parameters:

Installing the switch 18

• Switch IP settings

• VLAN settings

• XFP settings

• Port names and types

• Port trunking settings

• Interswitch X-Connect port settings

• SNMP settings

• User name and password settings

• Default access to various management interfaces

• NTP settings

IMPORTANT: See "Runtime switching software default settings (on page 33)" for a complete

list of default configuration settings.

Switch security

When planning the switch configuration, secure access to the management interface by:

• Creating users with various access levels

• Enabling or disabling access to various management interfaces to fit the security policy

• Changing default SNMP community strings for read-only and read-write access

User, operator, and administrator access rights

To enable better switch management and user accountability, three levels or classes of user access have been implemented on the switch. Levels of access to CLI, Web management functions, and screens increase as needed to perform various switch management tasks. Conceptually, access classes are defined as:

• User interaction with the switch is completely passive. Nothing can be changed on the switch. Users

can display information that has no security or privacy implications, such as switch statistics and current operational state information.

• Operators can only effect temporary changes on the switch. These changes will be lost when the

switch is rebooted/reset. Operators have access to the switch management features used for daily switch operations. Because any changes an operator makes are undone by a reset of the switch, operators cannot severely impact switch operation.

• Administrators are the only ones that can make permanent changes to the switch configuration,

changes that are persistent across a reboot/reset of the switch. Administrators can access switch functions to configure and troubleshoot problems on the switch. Because administrators can also make temporary (operator-level) changes as well, they must be aware of the interactions between temporary and permanent changes.

Access to switch functions is controlled through the use of unique user names and passwords. Once connected to the switch via the local console, Telnet, or SSH, a password prompt appears.

Installing the switch 19

NOTE: It is recommended to change the default switch passwords after initial configuration

and as regularly as required under the network security policies. For more information, see the

The default user name and password for each access level are:

HP 1:10Gb Ethernet BL-c Switch Command Reference Guide.

User account Description and tasks performed Password

User The user has no direct responsibility for switch management. He or she

can view all switch status information and statistics, but cannot make any configuration changes to the switch.

user

Operator The operator manages all functions of the switch. The operator can

reset ports or the entire switch. By default, the operator account is disabled and has no password.

Administrator The super user administrator has complete access to all menus,

information, and configuration commands on the switch, including the ability to change both the user and administrator passwords.

Manually configuring a switch

The switch is configured manually using a command line interface, a browser-based interface, or an SNMP interface. See the HP 1:10Gb Ethernet BL-c Switch Command Reference Guide for more information on using these management interfaces to configure the switch.

After a switch is configured, back up the configuration as a text file to a TFTP server. The backup configuration file is then downloaded from the TFTP server to restore the switch back to the original configuration. This restoration is necessary if one of these conditions apply:

• The switch configuration becomes corrupted during operation.

• The switch must be replaced because of a hardware failure.

Configuring multiple switches

admin

Configure multiple switches by using scripted CLI commands through Telnet or by downloading a configuration file using a TFTP server.

Using scripted CLI commands through Telnet

The CLI, provided with the switch, executes customized configuration scripts on multiple switches. A configuration script is tailored to one of the multiple switches, and then that configuration can be deployed to other switches from a central deployment server.

Using a configuration file

If planning for the base configuration of multiple switches in a network to be the same, manually configure one switch, upload the configuration to a TFTP server, and use that configuration as a base configuration template file.

Installing the switch 20

Switch IP addresses are acquired by default using BOOTP, therefore, each switch has a unique IP address. Each switch is remotely accessed from a central deployment server and an individual switch configuration is downloaded to meet specific network requirements. See the HP 1:10Gb Ethernet BL-c Switch Command Reference Guide for additional information on using a TFTP server to upload and download configuration files.

Installing the switch

CAUTION: Do not cable the switch until after configuration.

IMPORTANT: Make sure that the server NIC configuration matches the switch bay selected.

NOTE: When installing two switches, there is one switch interconnect port between adjacent

I/O bays. Port 17 is disabled by default. The port must be manually enabled to use.

Installing the switch 21

A successful installation is indicated by a green Health LED. If the Health LED is amber or power is not applied to the switch, see the "Troubleshooting" section of the HP BladeSystem enclosure setup and installation guide for more information.

Accessing the switch

The switch is accessed remotely using the Ethernet ports or locally using the DB-9 management serial port. To access the switch remotely:

1. Assign an IP address. By default, the switch is set up to obtain its IP address from a BOOTP server

existing on the attached network.

2. From the BOOTP server, use the switch MAC address to obtain the switch IP address.

3. From a computer connected to the same network, use the IP address to access the switch using a

Web browser or telnet application, which enables access to the switch BBI or CLI. The switch logon prompt appears.

Installing the switch 22

NOTE: If the switch does not obtain the IP address by means of the BOOTP service, access the

switch locally and configure the IP address manually. After assigning the IP address to the switch, then access the switch remotely.

To access the switch locally:

1. Connect the switch DB-9 serial connector, using a null-modem serial cable to a local client device

(such as a laptop computer) with VT100 terminal emulation software.

2. Open a VT100 terminal emulation session with these settings: 9600 baud rate, eight data bits, no

parity, one stop bit, and no flow control.

Logging on and configuring the switch

To log on to the switch:

1. Access the switch ("Accessing the switch" on page 22). After connecting to the switch console, the

2. Enter admin as the default administrator password.

The Main Menu appears and displays all administrator privileges:

See the HP 1:10Gb Ethernet Blade Switch for c-Class BladeSystem Command Reference Guide for information on configuring the IP address, changing configuration settings, and monitoring switch operation using one of the following interfaces:

• Local RS-232 serial console management interface

• Remote telnet console management interface

See the HP 1:10Gb Ethernet Blade Switch for c-Class BladeSystem Browser-based Interface Reference Guide for information on using the embedded HTML interface to manage the switch from anywhere on

the network using a standard browser, such as Netscape Navigator or Microsoft

Internet Explorer.

See "SNMP MIBs support (on page 48)" for more information on the SNMP agents. This section also describes how to use the MIBs to configure and monitor the switch using a generic SNMP manager, such as HP OpenView Network Node Manager or HP Systems Insight Manager.

CAUTION: Removing and installing an XFP transceiver can shorten the useful life. Do not

remove and insert XFP transceivers more often than is necessary.

CAUTION: HP recommends attaching an ESD-preventative wrist strap to your wrist and to a

bare metal surface on the chassis to prevent electrostatic discharge.

CAUTION: Do not remove the dust plugs from the fiber-optic XFP transceiver or the rubber caps

from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the XFP transceiver ports and cables from contamination and ambient light.

Performing a serial download

In this section

Introduction ........................................................................................................................................... 42

Serial upgrade of boot code firmware image procedure............................................................................. 42

Serial upgrade of operating system firmware procedure ............................................................................. 45

Introduction

Perform a serial download of the switch operating system firmware, or boot code firmware if upgrading a switch directly from any existing OS or boot code images.

This procedure requires:

• A computer running terminal emulation software

• A standard null modem cable with a female DB-9 connector

• A switch OS firmware and/or boot code images

Serial upgrade of boot code firmware image procedure

To perform a serial upgrade of the switch boot code firmware image, usually named GbE2c-1- 10G_b_100.bin:

1. Using the null modem, connect the console port of the switch to the serial port of a PC that supports

XModem/1K XModem.

2. Start HyperTerminal (part of Microsoft Windows) or equivalent terminal emulation application

(depending on the computer operating system), and set the parameters for the terminal emulation console:

Parameter Value

Baud rate 9600 Date bits 8 Parity None Stop bits 1 Flow control None

3. Power on the switch.

Performing a serial download 42

Hold down the Shift key and press the D key repeatedly during the Memory Test, until this message appears:

NOTE: To perform serial downloads at 57600 baud rate, press the Shift-F keys. To perform

serial downloads at 115200 baud rate, press the Shift-D keys.

5. After the message in Step 4 appears, reconfigure the terminal emulation console using these

parameters.

Parameter Value

Baud rate 115200 Data bits 8 Parity None Stop bits 1 Flow control None

6. Press the Enter key several times on the PC that is connected to the console port of the switch. When

the console port is successfully communicating with the PC, indicating readiness for image transfer, continuous C's appear:

7. Be sure that the new switch boot code firmware file is available on the computer. This file can be

downloaded from the CD that is shipped with the switch or from the HP website (http://www.hp.com/go/bladesystem/documentation

Performing a serial download 43

Select <Transfer-Send File> from the menu and choose these options in the Send File window:

The Send File window displays progress of the file transfer. The file transfer might take up to seven minutes.

NOTE: Although slower, XModem also works if 1K MODEM is not used.

9. After completing the transfer, a message displays how many bytes transferred, followed by another

message displaying the status of image extraction. Do not power cycle the switch during this process. After extracting the image, it is updated to flash and a message with a progress indicator displays as shown.

CAUTION: Do not power off the switch until the message: "Change your baud rate to 9600

Serial upgrade of operating system firmware procedure

To perform a serial upgrade of the switch operating system firmware image, usually named GbE2c-1- 10G_100.bin:

1. Using the null modem cable, connect the console port of the switch to the serial port of a PC that

supports XModem/1K XModem.

2. Start HyperTerminal (part of Microsoft Windows) or equivalent terminal emulation application

(depending on the computer operating system) and set the parameters for terminal emulation console:

Parameter Value

Baud rate 9600 Data bits 8 Parity None Stop bits 1 Flow control None

3. Power on the switch.

4. Hold down the Shift key and press the D key repeatedly during the Memory Test, until this message

appears:

Performing a serial download 45

NOTE: To perform serial downloads at 57600 baud rate, press the Shift-F keys. To perform

serial downloads at 115200 baud rate, press the Shift-D keys.

5. After the message in Step 4 appears, reconfigure the terminal emulation console using these

parameters.

Parameter Value

Baud rate 115200 Data bits 8 Parity None Stop bits 1 Flow control None

6. Press the Enter key several times on the PC that is connected to the console port of the switch. When

the console port is successfully communicating with the PC, indicating readiness for image transfer, continuous C's appear:

7. Be sure that the new switch operating system firmware file is available on the computer. This file can

be downloaded from the CD that is shipped with the switch or from the HP website (http://www.hp.com/go/bladesystem/documentation

8. Select <Transfer-Send File> from the menu and choose these options in the Send File window:

The Send File window displays the progress of the file transfer. The file transfer might take up to five minutes.

NOTE: Although slower, XModem also works if 1K MODEM is not used.

9. After completing the transfer, a message displays how many bytes transferred, followed by another

message displaying the status of image extraction. Do not power cycle the switch during this process.

CAUTION: Do not power off the switch until the message: "Change your baud rate to 9600

bps and power cycle the switch," is displayed, otherwise, the switch will be inoperable.

10. After extracting the image, the system prompts to select which current operating system image

(image1 or image2) needs to be updated by the new operating system image. It also provides an option (n) not to update any and to quit the update procedure.

Performing a serial download 46

Depending on the selection, 1 or 2, the system updates image1 or image2 on the flash and a message with a progress indicator displays as shown below. If selecting n, the system aborts the update procedure and prompts to reset the baud rate and power cycle the switch.

11. Change the baud rate to 9600 and power off the switch. Wait for a few seconds, and power on the

switch. During bootup the switch the following prompt appears:

To use the other operating system image, press the Ctrl-o keys.

MIB overview

Management and statistics information is stored in the switch in the MIB. The switch supports several standard MIBs. Values for MIB objects are retrieved with any SNMP-based network management software.

In addition to the standard MIBs, the switch also supports its own proprietary enterprise MIB as an extended MIB. The proprietary MIB is retrieved by specifying the MIB OID at the network manager station.

MIB values are either read-only or read/write variables.

• Read-only MIB variables are constants that are programmed into the switch or variables that change

while the switch is in operation. Examples of read-only constants include the number and types of ports. Examples of read-only variables are the statistics counters, such as the number of errors that have occurred or how many kilobytes of data have been received and forwarded through a port.

• Read/write MIB variables are usually related to user-customized configurations. Examples include

the IP address of the switch, Spanning Tree Algorithm parameters, and port status.

SNMP Manager software

Using third-party vendor SNMP software to manage the switch allows access to proprietary enterprise MIBs for the switch. The MIBs are found in the utilities on the HP website (http://www.hp.com/go/bladesystem/documentation

If the software provides functions to browse or modify MIBs, the MIB values (if the MIB attributes permit the write operation) are changeable. This process can be quite involved, because the MIB OIDs (available in the MIB files) must be used and retrieved one by one.

Use an SNMP manager, such as HP OpenView Network Node Manager or HP Systems Insight Manager, to access the enterprise-specific MIBs. Compile the MIBs into the MIB database and then use a MIB browser to navigate through them. For detailed information, access the individual descriptions of each MIB or see the documentation that came with the SNMP manager software.

The switch SNMP agent supports SNMP Version 1. Security is provided through SNMP community strings. The default community strings are "public" for SNMP GET operation and "private" for SNMP SET operation.

Users can specify up to two trap hosts for receiving SNMP traps. The agent sends the SNMP trap to the specified hosts when appropriate. Traps are not sent if there is no host specified.

Preventing electrostatic discharge............................................................................................................. 51

Grounding methods to prevent electrostatic discharge ................................................................................ 51

Preventing electrostatic discharge

To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

To prevent electrostatic damage:

• Avoid hand contact by transporting and storing products in static-safe containers.

• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.

• Place parts on a grounded surface before removing them from their containers.

• Avoid touching pins, leads, or circuitry.

• Always be properly grounded when touching a static-sensitive component or assembly.

Grounding methods to prevent electrostatic discharge

Several methods are used for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:

• Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist

straps are flexible straps with a minimum of 1 megohm ±10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet

when standing on conductive floors or dissipating floor mats.

• Use conductive field service tools.

• Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an authorized reseller install the part.

For more information on static electricity or assistance with product installation, contact an authorized reseller.
