Rack safety

Rack installation

DANGER

Observe the following precautions when working on or around your IT rack system:

v Heavy equipment—personal injury or equipment damage might result if

mishandled.

v Always lower the leveling pads on the rack cabinet.

v Always install stabilizer brackets on the rack cabinet.

v To avoid hazardous conditions due to uneven mechanical loading, always install

the heaviest devices in the bottom of the rack cabinet. Always install servers and optional devices starting from the bottom of the rack cabinet.

v Rack-mounted devices are not to be used as shelves or work spaces. Do not

place objects on top of rack-mounted devices.

v Each rack cabinet might have more than one power cord. Be sure to disconnect

all power cords in the rack cabinet when directed to disconnect power during servicing.

v Connect all devices installed in a rack cabinet to power devices installed in the

same rack cabinet. Do not plug a power cord from a device installed in one rack cabinet into a power device installed in a different rack cabinet.

v An electrical outlet that is not correctly wired could place hazardous voltage on

the metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock.

(R001 part 1 of 2) CAUTION:

v Do not install a unit in a rack where the internal rack ambient temperatures will

exceed the manufacturer’s recommended ambient temperature for all your rack-mounted devices.

v Do not install a unit in a rack where the air flow is compromised. Ensure that air

flow is not blocked or reduced on any side, front, or back of a unit used for air flow through the unit.

v Consideration should be given to the connection of the equipment to the supply

circuit so that overloading of the circuits does not compromise the supply wiring or overcurrent protection. To provide the correct power connection to a rack, refer to the rating labels located on the equipment in the rack to determine the total power requirement of the supply circuit.

v (For sliding drawers) Do not pull out or install any drawer or feature if the rack

stabilizer brackets are not attached to the rack. Do not pull out more than one drawer at a time. The rack might become unstable if you pull out more than one drawer at a time.

v (For fixed drawers) This drawer is a fixed drawer and must not be moved for

servicing unless specified by the manufacturer. Attempting to move the drawer partially or completely out of the rack might cause the rack to become unstable or cause the drawer to fall out of the rack.

(R001 part 2 of 2)

xviii IBM x-series of Ethernet Switches Installation and User Guide

Rack relocation (19″ rack)

CAUTION: Removing components from the upper positions in the rack cabinet improves rack stability during relocation. Follow these general guidelines whenever you relocate a populated rack cabinet within a room or building:

v Reduce the weight of the rack cabinet by removing equipment starting at

the top of the rack cabinet. When possible, restore the rack cabinet to the configuration of the rack cabinet as you received it. If this configuration is not known, you must do the following:

– Remove all devices in the 32U position and above. – Ensure that the heaviest devices are installed in the bottom of the rack

cabinet.

– Ensure that there are no empty U-levels between devices installed in the

rack cabinet below the 32U level.

– If the rack cabinet you are relocating is part of a suite of rack cabinets,

detach the rack cabinet from the suite.

– Inspect the route that you plan to take when moving the rack to

eliminate potential hazards.

– Verify that the route that you choose can support the weight of the

loaded rack cabinet. Refer to the documentation that came with your

rack cabinet for the weight of a loaded rack cabinet. – Verify that all door openings are at least 760 x 2030 mm (30 x 80 in.). – Ensure that all devices, shelves, drawers, doors, and cables are secure. – Ensure that the four leveling pads are raised to their highest position. – Ensure that there is no stabilizer bracket installed on the rack cabinet

during movement. – Do not use a ramp inclined at more than 10 degrees. – Once the rack cabinet is in the new location, do the following:

- Lower the four leveling pads.

- Install stabilizer brackets on the rack cabinet.

- If you removed any devices from the rack cabinet, repopulate the rack cabinet from the lowest position to the highest position.

– If a long distance relocation is required, restore the rack cabinet to the

configuration of the rack cabinet as you received it. Pack the rack cabinet in the original packaging material, or equivalent. Also, lower the leveling pads to raise the casters off of the pallet and bolt the rack cabinet to the pallet.

Attaching a PC or terminal

To assign an IP address, you must have access to the Command Line Interface (CLI). The CLI is a text-based interface that can be accessed through a direct serial connection to the device or through Telnet connections.

Chapter 2. Installing the B24X 15

You will need to assign an IP address using the CLI. You can access the CLI by attaching management station through a serial cable to the Console port. After you assign an IP address, you can access the system through Telnet or IronView Network Manager.

Complete the following steps to attach a management station using the serial port:

1. Use a straight-through cable to connect a PC or terminal to the male DB-9 serial port connector.

Note: You need to run a terminal emulation program on the PC.

2. Open the terminal emulation program and set the session parameters as follows:

v Baud: 9600 bps v Data bits: 8 v Parity: None v Stop bits: 1 v Flow control: None

When you establish the serial connection to the system, press Enter to display the CLI prompt in the terminal emulation window. For example:

TurboIron>

When you see one of these prompts, you are connected to the system and can proceed to “Assigning permanent passwords” on page 19.

You can customize the prompt by changing the system name. Refer to the FastIron and TurboIron 24X Configuration Guide.

If you do not see a prompt:

v Make sure the cable is securely connected to your PC and to the device. v Check the settings in your terminal emulation program. In addition to the session

settings listed above, make sure the terminal emulation session is running on the same serial port you attached to the device.

The EIA or TIA 232 serial communication port serves as a connection point for management by a PC or SNMP workstation. The switches come with a standard male DB-9 connector, shown in Figure 8 on page 17.

By default, the CLI is not protected by passwords. To secure CLI access, IBM strongly recommends assigning passwords.

Note: You can assign passwords using IronView Network Manager if an enable

password for a Super User has been configured on the device.

The CLI contains the following access levels: v User EXEC-The level you enter when you first start a CLI session. At this level,

you can view some system information but you cannot configure system or port parameters.

v Privileged EXEC-Also called the Enable level, and can be secured by a

password. At this level, you can perform tasks such as manage files on the flash module, save the system configuration to flash, and clear caches.

v CONFIG-This level lets you configure the system IP address, and switching and

routing features. To access the CONFIG mode, you must already be logged into the Privileged level of the EXEC mode (the Enable level).

You can set the following levels of Enable passwords: v Super User - Allows complete read-and-write access to the system. This is

generally for system administrators and is the only password level that allows you to configure passwords.

Note: You must set a super user password before you can set other types of

passwords.

v Port Configuration - Allows read-and-write access for specific ports but not for

global (system-wide) parameters.

v Read Only - Allows access to the Privileged EXEC mode and CONFIG mode but

only with read access.

Complete the following steps to set passwords:

1. At the opening CLI prompt, enter the following command to change to the Privileged level of the EXEC mode.

TurboIron> enable

2. Access the CONFIG level of the CLI by entering the following command.

TurboIron# configure terminal TurboIron(config)#

3. Enter the following command to set the super-user password.

TurboIron(config)# enable super-user-password <text>

Note: You must set the super user password before you can set other types of

passwords.

4. Enter the following commands to set the port configuration and read-only passwords.

TurboIron(config)# enable port-config-password <text> TurboIron(config)# enable read-only-password <text>

Note: If you forget your super user password, refer to “Recovering from a lost

password.”

Syntax: enable super-user-password | read-only-password | port-config-password <text>

Passwords can be up to 32 characters long.

Recovering from a lost password

By default, the CLI does not require passwords. However, if someone has configured a password for the device but the password has been lost, you can regain super-user access to the device using the following procedure.

Note: Recovery from a lost password requires direct access to the serial port and a

system reset.

Complete the following steps to recover from a lost password:

1. Start a CLI session over the serial interface to the device.

2. Reboot the device.

3. While the system is booting, before the initial system prompt appears, enter b to enter the boot monitor mode.

4. Enter no password at the prompt. (You cannot abbreviate this command.)

5. Enter boot system flash primary at the prompt. This command causes the device to bypass the system password check.

6. After the console prompt reappears, assign a new password.

Configuring IP addresses

You must configure at least one IP address using the serial connection to the CLI before you can manage the system using the other management interfaces. In addition, routers require an IP subnet address for the subnet in which you plan to place them in your network.

The x-series devices support both classical IP network masks (Class A, B, and C subnet masks, and so on) and Classless Interdomain Routing (CIDR) and network prefix masks as follows:

v To enter a classical network mask, enter the mask in IP address format. For

example, for an IP address with a Class-C subnet mask enter the following:

209.157.22.99 255.255.255.0

v To enter a prefix number for a network mask, enter a forward slash(/)andthe

number of bits in the mask immediately after the IP address. For example, enter the following for an IP address that has a network mask with 24 significant (“mask”) bits:

209.157.22.99/24

By default, the CLI displays network masks in classical IP address format (example:

255.255.255.0). You can change the display to the prefix format. Refer to the

FastIron and TurboIron 24X Configuration Guide.

20 IBM x-series of Ethernet Switches Installation and User Guide

Devices running Layer 2 software

Complete the following steps to configure an IP address on a device running Layer 2 software:

1. At the opening CLI prompt, enter enable.

TurboIron> enable

2. Enter the following command at the Privileged EXEC level prompt (for example, TurboIron Switch#), then press Enter. This command erases the factory test configuration if still present.

TurboIron# erase startup-config

3. Access the configuration level of the CLI by entering the following command.

TurboIron# configure terminal Privileged EXEC Level TurboIron(config)# Global CONFIG Level

4. Configure the IP address and mask for the switch.

TurboIron(config)# ip address 192.22.3.44 255.255.255.0

5. Set a default gateway address for the switch.

TurboIron(config)# ip default-gateway 192.22.3.1

Note: You do not need to assign a default gateway address for single subnet

networks.

Syntax: enable [<password>]

Syntax:configure terminal

Syntax:[no] ip address <ip-addr> <ip-mask>

Syntax:[no] ip address <ip-addr>/<mask-bits>

Syntax: ip default-gateway <ip-addr>

Connecting network devices

IBM devices support connections to routers, switches, and hubs from other vendors, as well as other IBM devices.

Connectors and cable specifications

Refer to “Cable specifications” on page 46 for cable lengths and types supported on the B24X devices. For port pinouts, refer to “10/100/1000 Gigabit port pinouts” on page 46.

Connecting to Ethernet or fast Ethernet hubs

For copper connections to Ethernet hubs, a 10/100Base-TX or 1000Base-T switch, or another device, a crossover cable is required (Figure 10 on page 22 and

Chapter 3. Connecting Network Devices and Checking Connectivity 21

UTP crossover cable 10/100BaseTX

Figure 11). If the hub is equipped with an uplink port, it will require a straight-through cable instead of a crossover cable.

Note: The 802.3ab standard (automatic MDI or MDIX detection) calls for automatic

negotiation of the connection between two 1000Base-T ports. Therefore, a crossover cable may not be required; a straight-through cable may work as well. For more information about this feature, refer to the FastIron and TurboIron 24X Configuration Guide.

Connecting to workstations, servers, or routers

Straight-through UTP cabling is required for direct UTP attachment to workstations, servers, or routers using network interface cards (NICs).

Fiber cabling is required for direct attachment to Gigabit NICs or switches and routers through fiber ports. Refer to “Connecting a network device to a fiber port.”

Automatic MDI or MDIX detection

All 10/100/1000 Copper ports on the B24X devices support automatic Media Dependent Interface (MDI) and Media Dependent Interface Crossover (MDIX) detection. This feature is enabled on all Gigabit copper ports by default. For each port, you can disable auto MDI or MDIX, designate the port as an MDI port, or designate the port as an MDIX port.

For more information about this feature and how configure it, refer to the FastIron and TurboIron 24X Configuration Guide.

Connecting a network device to a fiber port

For direct attachment from the device to a Gigabit NIC, switch, or router, fiber cabling with an LC connector is required.

To connect the device to another network device using a fiber port, you must do the following:

v Install a fiber optic module (SFP transceiver or mini-GBIC for Gigabit Ethernet

ports, or SFP+ transceiver for 10-Gigabit Ethernet ports)

v Cable the fiber optic module

The following sections provide information about performing these tasks.

Installing a fiber optic module: You must install a fiber optic module (SFP or SFP+ transceiver) in each Gigabit Ethernet and 10-Gigabit Ethernet fiber port you want to use.

You can install a new fiber optic module in a port while the device is powered on and running.

To install a fiber optic module, you will need an ESD wrist strap with a plug for connection to a metal surface.

CAUTION: For safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor.

Complete the following steps to install a fiber optic module:

1. Put on the ESD wrist strap and ground yourself by attaching the clip end to a metal surface (such as an equipment rack) to act as ground.

2. Remove the new module from its protective packaging.

3. Gently insert the fiber optic module into the port until the module clicks into place. The module is keyed to prevent incorrect insertion.

Cabling a fiber optic module: Complete the following steps to cable a fiber optic module:

Chapter 3. Connecting Network Devices and Checking Connectivity 23

1. Remove the protective covering from the fiber-optic port connectors and store the covering for future use.

2. Before cabling a fiber optic module, clean the cable connectors and the port connectors thoroughly. For more information, refer to “Cleaning the fiber-optic connector.”

3. Gently insert the cable connector or connectors (a tab on each connector should face upward) into the port connector or connectors until the tabs lock into place.

4. Observe the link and active LEDs to determine if the network connections are functioning properly. Refer to Table 8 on page 25.

Cleaning the fiber-optic connector: To avoid problems with the connection between the fiber optic module (SFP (mini-GBIC) or SFP+) and the fiber cable connectors, clean both connectors thoroughly each time you disconnect and reconnect them. In particular, dust can accumulate in the connectors and cause problems such as reducing the optic launch power.

When not using an SFP or SFP+ connector, make sure to keep the protective covering on.

Testing connectivity

After you install the network cables, you can test network connectivity to other devices by pinging those devices. You also can observe the LEDs related to network connection and perform trace routes.

Pinging an IP address

To verify that a device can reach another device through the network, enter a command such as the following at any level of the CLI on the device.

TurboIron> ping 192.33.4.7

Syntax: ping <ip addr> | <hostname> [source <ip addr>] [count <num>] [timeout <msec>] [ttl <num>] [size <byte>] [quiet] [numeric] [no-fragment] [verify] [data <1-to-4 byte hex>] [brief]

Note: If you address the ping to the IP broadcast address, the device lists the first

four responses to the ping.

Observing LEDs

After you install the network cables, you can observe certain LEDs to determine if the network connections are functioning properly. Table 8 on page 25 describes the LEDs related to network connections, the desired state of each LED, possible abnormal states of each LED, and what to do if an LED indicates an abnormal state.

24 IBM x-series of Ethernet Switches Installation and User Guide

Table 8. Network connection-related LED states

LED Desired State Meaning

Link (Lnk) On (Green) A link is

established with the remote port.

Active (Act) On or blinking

(Yellow)

The port is transmitting and receiving user packets.

Abnormal State Meaning or Action

Off A link is not established with the remote

port. You can do the following: v Verify that the connection to the other

network device has been properly made. Also, make certain that the other network device is powered on and operating correctly.

v Verify that the transmit port on the

device is connected to the receive port on the other network device, and that the receive port on the device is connected to the transmit port on the other network device. If you are uncertain, remove the two cable connectors from the port connector and reinsert them in the port connector, reversing their order.

v Dust may have accumulated in the cable

connector or port connector. For information about cleaning the connectors, refer to “Cleaning the fiber-optic connector” on page 24.

v If the other actions don’t resolve the

problem, try using a different port or a different cable.

Off for an extended period.

The port is not transmitting or receiving user packets. You can do the following:

v Check the Link LED to make sure the

link is still established with the remote port. If not, take the actions described in the Meaning or Action column for the Link LED.

v Verify that the port has not been

disabled through a configuration change. You can use the CLI. If you have configured an IP address on the device, you also can use IronView Network Manager.

If a problem persists after taking these actions, contact IBM technical support.

Tracing a route

To determine the path through which a device can reach another device, enter a command such as the following at any level of the CLI on the device.

TurboIron> traceroute 192.33.4.7

Syntax:traceroute <host-ip-addr> [maxttl <value>] [minttl <value>] [numeric] [timeout <value>] [source-ip <ip addr>]

The CLI displays trace route information for each hop as soon as the information is received. Traceroute requests display all responses to a given TTL. In addition, if there are multiple equal-cost routes to the destination, the device displays up to three responses by default.

Chapter 3. Connecting Network Devices and Checking Connectivity 25

Troubleshooting network connections

v For the indicated port, verify that both ends of the cabling (at the device and the

connected device) are snug.

v Verify that the device and the connected device are both powered on and

operating correctly.

v Verify that you have used the correct cable type for the connection:

– For twisted-pair connections to an end node, use straight-through cabling. – For fiber-optic connections, verify that the transmit port on the device is

connected to the receive port on the connected device, and that the receive port on the device is connected to the transmit port on the connected device.

v Verify that the port has not been disabled through a configuration change. You

can use the CLI. If you have configured an IP address on the device, you also can use IronView Network Manager.

v For copper ports, you can test the cable using Virtual Cable Testing (VCT). Refer

to “Monitoring Hardware Components” in the FastIron and TurboIron 24X Configuration Guide.

v If the other procedures don’t resolve the problem, try using a different port or a

different cable.

Support for digital optical monitoring

You can configure your device to monitor optical transceivers in the system, either globally or by specified port. When this feature is enabled, the system monitors the temperature and signal power levels for the optical transceivers in the specified ports. Console messages and syslog messages are sent when optical operating conditions fall below or rise above the SFP+ or SFP manufacturer recommended thresholds. For more information about digital optical monitoring, refer to the FastIron and TurboIron 24X Configuration Guide.

26 IBM x-series of Ethernet Switches Installation and User Guide

Chapter 4. Managing the B24X

This chapter contains information about how to manage temperature settings and how to remove MAC address entries.

Managing temperature settings

This section describes how to display temperature settings on the B24X and how to change the temperature warning levels.

Using the temperature sensor

The B24X comes with two built-in temperature sensors; one at the air intake, and the other at the exhaust (refer to Figure 27 on page 44). The temperature sensor at the air intake monitors the incoming air temperature. The temperature sensor at the air exhaust monitors the air temperature as it exits the device. The temperature sensors cause the device to generate a Syslog message and SNMP trap if the temperature exceeds a specified warning level The software reads the temperature sensors according to the device poll time, which is 60 seconds by default. If the temperature equals or exceeds the warning temperature the software generates a Syslog message and SNMP trap.

You can use the CLI to perform the following:

v “Displaying the temperature” v “Changing the temperature warning level” on page 28 v “Changing the device temperature polling interval” on page 28

Displaying the temperature

By default, the software polls the temperature sensor every 60 seconds to get the current temperature. This poll rate is controlled by the device poll time, which also controls how often the software polls other system components.

To display the temperature of a device, enter the show chassis command at any level of the CLI. The following shows an example output.

TurboIron#show chassis Power supply 1 (NA - NA - Regular) present, status ok Power supply 2 not present

Fan 1 ok, speed (auto):
