Figure 1-4 PCM — Back Plate

Each blade is capable of simultaneously driving all six fans in both PCMs. Normally, only one blade controls both fans, running them at a normal speed. However, if the system detects higher than expected temperature on either side of the blade, it forces the fans to run at full speed. Once the temperature is back to normal, the fans resume running at their normal speed.

CPU1	60°C	55°C	68°C	55°C

CPU2	60°C	55°C	68°C	55°C

The following paragraphs describe the fan speed and temperature parameters listed in Table 1-1.

High Fan Speed Temperature – When a sensor detects a temperature that exceeds this value, the fan speed will run at their maximum RPM. The system logs the event and the system fault LED blinks five times every two seconds.

Low Fan Speed Recovery Temperature – When the fans are running at their maximum RPM and all sensors report values less than this value, the fan speed resets to normal.

Critical Temperature – When a sensor detects a temperature that exceeds this value, the system powers down the blade. When this happens, the CPUs enter sleep state 5; the system sets the PCI power state of capable devices to D3 and turns off the power supplies not essential to wake up the CPUs. When the temperature goes below the Recovery Temperature value, the sensor that reported the over temperature value will generate an SMB_ALERT.

Recovery Temperature – Value at which a sensor will generate an SMB_ALERT to wake up the CPU and cause the blade to reboot.

Introduction

iSR6250 Router Blades

Input Power LED (Green)

The power LED shows the voltage status of the router logic circuit board. During normal operation, this LED lights up to show that the router logic circuit board is receiving the DC voltage from the power supply.

Beacon Indicator (Blue)

The iSR6250 router blade’s PCB has a blue beacon light installed near the center vent hole between the FC ports (Figure 1-6). This light enables you to locate the physical blade when monitoring the iSR6250 routers using the SANsurfer Router Manager. If you enable the Beacon On option for a selected blade in the Router Manager, the blue beacon light flashes through the vent hole on the chassis blade’s face plate.

Maintenance Button

The maintenance button shown in Figure 1-7 is the only router blade control. Press this button to reset the router blade or to recover it if it becomes disabled.

Reset a Router Blade

To reset the router blade, use a pointed, nonmetallic tool to momentarily press and release (less than two seconds) the maintenance button. The router responds as follows:

1.All the router blade LEDs illuminate.

2.After about 2 seconds, the POST begins, turning off the heartbeat and system fault LEDs.

3.When the POST is complete, the power LED is on and the heartbeat LED flashes once per second.

Reset and Select Boot Image

You can reset the router using either the primary or secondary boot image:

Primary Image – To reset the router and select the primary boot image, use a pointed, nonmetallic tool to press and hold the maintenance button until the heartbeat LED flashes once, then release the button. The router will boot from the primary boot image. The boot time is less than one minute.

Secondary Image – To reset the router and select the secondary boot image, use a pointed, nonmetallic tool to press and hold the maintenance button until the heartbeat LED flashes twice, then release the button. The heartbeat LED flashes twice. The router boots from secondary boot image. The boot time is less than one minute.

Reset IP Address

To reset the router and restore the maintenance port IP address to the default (10.0.0.1), use a pointed, nonmetallic tool to press and hold the maintenance button until the heartbeat LED flashes six times, then release the button. The router boots and sets the maintenance port to IP address 10.0.0.1. The boot time is less than one minute.

The IP address set by this method is not persistent; to make the change persistent, use the command line interface (CLI) or SANsurfer Router Manager to set the IP address. For more information, see the iSR6200 Router Manager User's Guide and the iSR6200 Router CLI User's Guide.

Enable DHCP

To reset the router and configure the maintenance port to use DHCP to acquire its IP address, use a pointed, nonmetallic tool to press and hold the maintenance button until the heartbeat LED flashes seven times, then release the button. The router boots and configures the maintenance port for DHCP. The boot time is less than one minute.

Enabling DHCP by this method is not persistent; to make the change persistent, use the command line interface (CLI) or SANsurfer Router Manager to enable DHCP. For details, see the iSR6200 Router Manager User's Guide and the iSR6200 Router CLI User's Guide.

Restore Factory Defaults

To reset the router and restore it to the factory default configuration, use a pointed, nonmetallic tool to press the maintenance button and hold it until the heartbeat LED flashes 20 times, then release the button. The router boots and is restored to the factory defaults. The boot time is less than one minute.

The router does the following when restored to the factory defaults:

Clears all router log entries.

Resets all passwords.

Resets the maintenance port IP address to 10.0.0.1.

Disables the iSCSI ports and sets the IP address to 0.0.0.0.

Erases all presentations.

Introduction

iSR6250 Router Blades

Fibre Channel Transceivers

Each port is served by a small form-factor pluggable (SFP) optical transceiver and is capable of 1-, 2-, 4-, or 8-Gbps transmission. SFPs are hot-pluggable. User ports can self-discover both the port type and transmission speed when connected to public devices or switches.

The iSR6250 router supports SFP optical transceivers for the Fibre Channel ports. A transceiver converts electrical signals to and from optical laser signals to transmit and receive data. Duplex fiber optic cables plug into the transceivers, which then connect to the devices. For example, a 1-Gbps/2-Gbps Fibre Channel port can transmit at 1-Gbps or 2-Gbps; however, the transceiver must also be capable of delivering these rates.

The SFP transceivers are hot pluggable. You can remove or install a transceiver while the router is operating without harming the router or the transceiver. However, this interrupts communication with the connected device. See page 3-7 for information about installing and removing SFP optical transceivers.

Gigabit Ethernet Port LEDs

The Gigabit Ethernet ports shown in Figure 1-9 are RJ-45 connectors that provide connection to an Ethernet SAN through a 100/1000 Base-T Ethernet cable. The ports are labeled GE1 and GE2. Each of these ports supports connections that run the iSCSI high-level TCP protocol.

2 Planning

This section describes how to plan for the iSR6250 router. The following sections describe the devices and services you need to consider when planning to use the iSR6250 router:

“Devices” on page 2-1

“Device Access” on page 2-2

“FC Switches Required for VPGroups” on page 2-2

“FC Performance” on page 2-2

“iSCSI Performance” on page 2-3

“Performance Tuning” on page 2-4

“High Availability” on page 2-7

“Management” on page 2-7

“Recovery” on page 2-7

“Services” on page 2-8

“Security” on page 2-8

Devices

When planning to use the router, consider the number of devices and the anticipated demand. This determines the number of ports required and in turn the number of routers.

The router uses SFP transceivers in the 8-Gbps Fibre Channel (FC) ports, but some FC devices may not use the same transceivers. Consider whether the FC device you want to connect the router to uses SFP or gigabit interface converters (GBIC) transceivers, and choose fibre optic cables accordingly. Use LC-type cable connectors for SFP transceivers and SC-type cable connectors for GBIC transceivers. Also consider the transmission speed compatibility of your devices, host bus adapters (HBAs), switches, and SFPs.

SN0051103-00 A

2-1

Planning

Device Access

Consider device access needs within the FC and iSCSI SANs. Controlling access to FC device LUNs requires mapping FC device LUNs to specific iSCSI initiators. You may map LUNs to more than one initiator. Giving multiple initiators access to a LUN requires access management.

Fibre Channel

The Fibre Channel ports automatically discover all FC target devices, whether connected directly (loop) or by fabric (switch).

iSCSI

The iSCSI ports automatically present targets discovered on the Fibre Channel ports. If the FC target’s LUN 0 is a controller LUN, it becomes accessible (mapped) to all iSCSI initiators. All data LUNs are inaccessible until mapped. The exception to this is if LUN 0 is a controller LUN, then it is mapped automatically to allow for management of the FC target controller.

When an iSCSI initiator logs on, the router records the initiator’s iSCSI name and IP address. The management interface [command line interface (CLI) and SANsurfer Router Manager] uses the initiator information to simplify the mapping process.

FC Switches Required for VPGroups

iSR6250 uses QLogic HBA technology and is compatible with all Fibre Channel switches from Brocade, Cisco, McData, and QLogic. If you want to use more than one VPGroup, you must use Fibre Channel Switches.

FC Performance

The iSR6250 router supports Fibre Channel service at transmission rates of 2, 4, or 8 Gbps with a maximum frame size of 2148 bytes. Related performance characteristics include the following:

Distance (see page 2-3)

Bandwidth (see page 2-3)

Latency (see page 2-3)

2-2	SN0051103-00 A

Planning

iSCSI Performance

Distance

Consider the physical distance between Fibre Channel devices. Choose SFP transceivers that are compatible with the cable type and distance.

Each Fibre Channel port is supported by a data buffer with a three-credit capacity; that is, three maximum sized frames. For fibre optic cables, this enables full bandwidth over the following approximate distances:

5 kilometers at 1 Gbps (0.6 credits/Km)

2.5 kilometers at 2 Gbps (1.2 credits/Km)

Beyond these distances, however, the connection loses some efficiency because the transmitting port must wait for an acknowledgement before sending the next frame.

Bandwidth

Bandwidth is a measure of the volume of data that can be transmitted at a given transmission rate. A 1-Gbps/2-Gbps FC port can transmit or receive at nominal rates of 1- or 2-Gbps, depending on the device to which it is connected. This corresponds to actual bandwidth values of 106 MB and 212 MB, respectively.

Latency

Latency is a measure of how fast a transaction travels through the router.

iSCSI Performance

The iSR6250 router supports Ethernet service at transmission rates of 1000-, 100or 10-Mbps with an MTU size of 1500 or 9000 (jumbo frames).

NOTE:

An MTU size greater than 1500 should only be used when the router is connected to a 1000 Mbps Ethernet network.

Related performance characteristics include the following:

Distance

Bandwidth

Latency

Distance

Consider the physical distance between routers.This is usually measured in round-trip delay. Round-trip delays range anywhere from less than 1 millisecond to as great as 250 milliseconds.

Planning

Performance Tuning

Bandwidth

Bandwidth is a measure of the volume of data that can be transmitted at a given transmission rate. WAN data rates range from 1.5 megabits per second (T1) to greater than 600 megabits per second (OC-12).

Latency

Latency is a measure of how fast a transaction travels through the router and LAN/WAN.

Performance Tuning

Proper configuration maximizes the router’s performance. Knowing the round trip delay (distance between the router and iSCSI initiators) and WAN effective data rate (connection type) allows you to tune the router for optimal performance. The following tables provide TCP Window Size settings for specific WAN environments. The TCP Window Size is configured as two parameters: Window Size and Scaling Factor. See the iSR6200 Router Manager User's Guide and the iSR6200 Router CLI User's Guide for configuring the TCP window size.

Planning

High Availability

A dual-blade iSR6250 router supports high availability, which provides link-level, switch-level, and blade-level failure protection. To make this effective, you must connect the iSCSI hosts to both iSR6250 blades. For details, see “Connecting iSCSI Hosts to your iSR6250” on page 4-13.

Management

The SANsurfer Router Manager application and CLI run on a management workstation used to configure, control, and maintain the router. Support platforms include Windows, Solaris, and Linux. The SANsurfer Router Manager application is installed and executed on the workstation.

The router supports the following management interfaces:

SANsurfer Router Manager – Graphical user interface (GUI) application, which runs on a management workstation (see the iSR6200 Router Manager User's Guide).

CLI – Command line interface, which runs on the router; users can access the CLI via telnet or the serial port (see the iSR6200 Router CLI User's Guide).

SNMP – Provides router status, traps, and alerts (see Appendix B).

Recovery

You should have a process in place to recover from a possible router failure. Consider the following when developing a recovery process for the router:

Save all firmware image files (updates) in a safe, well-known place, because you may:

Want to revert to a previous firmware version.

Need the firmware image when adding a router to your site.

Save the router’s configuration (as a new file) after every configuration change, because you may want to revert to a previous configuration.

Save the router’s LUN mappings (as a new file) after every mapping change, because you may:

Want to revert to a previous LUN mapping.

Want to duplicate the LUN mapping on a second router (for redundancy).

SN0051103-00 A

Planning

Services

NOTE:

For more details on recovering a router blade, see “iSR6250 Chassis Blades” on page 6-2.

Services

You can configure your router to suit the demands of your environment using a variety of router services. Familiarize yourself with the following router services and determine which ones you need:

Telnet – Enables you to manage the router over a telnet connection.

Router management – Provides for out-of-band management of the router with the SANsurfer Router Manager.

Simple network management protocol (SNMP) – Enables you to monitor the router using third-party applications that use SNMP.

Network time protocol (NTP) – Enables you to synchronize the router and the workstation dates and times with an NTP server. NTP is disabled (not configured) by default.

File transfer protocol (FTP) – Enables you to transfer files rapidly between the workstation and router using FTP.

Secure SHell (SSH) – Provides secure and encrypted connections to traditionally non-encrypted services.

Security

Passwords provide router security. The SANsurfer Router Manager requires a password each time a user logs into the application. Once connected, the SANsurfer Router Manager prompts for an administrative password before it accepts configuration changes.

The CLI also requires the user to enter a user ID and password to start. CLI must be in an admin session to perform any set operations. An admin session requires a password.

The default password for both these management tools is password for the default user ID of guest. The default administrative password is config.

Once logged on, you can change the password using the application’s security features.

An electrical outlet that is not correctly wired could place hazardous voltage on metal parts of the router chassis. The customer must make sure the outlet is correctly wired and grounded to prevent electrical shock.

You may require a different power cable in some countries because the plug on the cable supplied with the equipment will not fit your electrical outlet. In this case, you must supply your own power cable. The cable must meet the following requirements:

For 125 Volt electrical service: the cable must be rated at 10 Amps and be approved by UL and CSA.

For 250 Volt electrical service: the cable must be rated at 10 Amps, meet requirements of H05VV-F, and be approved by VDE, SEMKO, and

DEMKO.

Figure 3-1 shows the front and back plates of an iSR6250 router chassis that contains two router blades with add-in ports installed for its model. Each power cooling module (PCM) provides a power connector, as well as a Status LED.

Installation

Installing the iSR6250 Router

To power on the router:

1.Attach the AC power cord to the power connector, located on the back side of the PCM connected directly behind the router blade.

2.Connect the opposite end of the power cord to a grounded AC wall outlet or power strip.

3.Check the PCM power LED to make sure the fan is operational (green = OK, yellow = no AC power).

Figure 3-2 shows the location of the ports and LEDs on one of the blades contained within the iSR6250 unit that are referenced in the following instructions.

4.Verify that the router’s input power LED is illuminated. The iSR6250 router runs its self test and begins normal operation—this may take a minute.

5.Verify that the heartbeat LED is blinking (once per second) and that the system fault LED is not illuminated.

If an error has occurred, the system fault LED will blink a pattern that indicates the fault reason. For more information about error blink patterns, see page 5-3.

Connect the Management Workstation to the Router

You can manage the router using the SANsurfer Router Manager or the command line interface (CLI). SANsurfer Router Manager requires an Ethernet connection to the router. CLI can use an Ethernet connection or a serial connection. Choose the router management method, then connect the management workstation to the router in one of the following ways:

Indirect Ethernet connection from the management workstation to the router RJ-45 connector through an Ethernet switch or hub. This requires a 10/100 Base-T straight cable.

Installation

Installing the iSR6250 Router

Direct Ethernet connection from the management workstation to the router RJ-45 Ethernet connector. This requires a 10/100 Base-T crossover cable.

Serial port connection from the management workstation to the router RS-232 serial port connector. This requires a 10/100 Base-T straight cable and a dongle.

Configure the Management Workstation

The router comes from the factory with a default IP address (10.0.0.1). Prior to product installation, follow the procedures based on your configuration method:

If you plan to configure the router through the management Ethernet port (using the SANsurfer Router Manager or CLI via telnet), you must initially configure the workstation as described in “Setting the Workstation IP Address” on page 3-10.

If you plan to configure the router using the management COM port, configure the workstation as described in “Configuring the Workstation Serial Port” on page 3-11.

Setting the Workstation IP Address

The IP address of a new router is 10.0.0.1. To ensure that your workstation is configured to communicate with the 10.0.0 subnet, refer to the following instructions for your workstation:

Steps for different versions of Windows vary. For a Windows 2000 workstation, do the following:

a.From the Windows Start menu, select Settings>Control Panel>Network and Dial-up Connections.

b.Click Make New Connection.

c.Click Connect to a private network through the Internet, then click Next.

d.Enter 10.0.0.253 for the IP address.

For different versions of Windows, consult the Windows Help files.

For Linux or Solaris workstation, open a command window and enter the following command, where <interface> is your interface name: ifconfig <interface> ipaddress 10.0.0.253 netmask 255.255.255.0 up

Configuring the Workstation Serial Port

To configure the workstation serial port:

1.Connect the cable with RJ45 to DB9F adapter from a COM port on the management workstation to the serial port on the router.

2.Configure the workstation serial port according to your platform. These steps may vary according to the version of operating system you use:

For Windows:

a.Open the HyperTerminal application. From the Windows Start menu, select Programs> Accessories>HyperTerminal>HyperTerminal.

b.Enter a name for the router connection, choose an icon in the Connection Description window, then click OK.

c.Enter the following COM Port settings in the COM Properties window and click OK.

Bits per second – 115200 Data Bits – 8

Parity – None Stop Bits – 1

Flow Control – None

For Linux:

a.Set up minicom to use the serial port. Create or modify the /etc/minirc.dfl file with the following content:

pr portdev/ttyS0 pu minit

pu mreset pu mhangup

pr portdev/ttyS0 specifies port 0 on the workstation. Choose the pr setting to match the workstation port to which you connected the router.

b.Verify that all users have permission to run minicom. Review the /etc/minicom.users file and confirm that the line ALL exists or that there are specific user entries.

For Solaris – Modify the /etc/remote file to include the following lines. /dev/term/a refers to serial port a. Choose the “dv” setting to match the workstation port to which you connected the router.

\:dv=/dev/term/a:br#115200:el=^C^S^Q^U^D:ie=%$:oe=^ D:

3.Connect the router to the power (see page 3-13).
