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)

xvi Ethernet y-series Installation and User Guide: 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.

Chapter 1. Product overview 3

Serial management interface (DB9 Console port)

The serial management interface allows you to configure and manage the device using a third-party terminal emulation application on a directly-connected PC. A straight-through EIA or TIA DB9 serial cable ships with the device. The serial management interface (DB9 Console port) is located on the left side of the front panel.

Out-of-band 10/100/1000 MbE RJ45 management interface

The out-of-band 10/100/1000 MbE RJ45 management interface enables you to configure and manage the device on an Ethernet management network. The device can be managed using a variety of methods including the CLI via Telnet or SSH, using the web-based GUI via HTTP/HTTPS, and 3rd party SNMP applications such as IBM Systems Director.

Note: This port interfaces with the CPU only and not the data plane.

Network interfaces for 4002-Y2B and 4002-Y4B

The 4002-Y2B and 4002-Y4B models contain the following interfaces:

v 10/100/1000 MbE ports with RJ45 copper connectors v 100/1000 MbE ports with mini-GBIC slots for MSA-compliant SFP transceivers v Optional 2-port 10 GbE XFP module v 16/10 Gbps CX4 ports

Network interfaces for 4002-Y2A, Y4A, Y2C, and Y4C

The 4002-Y2A ,Y4A, Y2C, and Y4C models contain the following interfaces:

v 10/100/1000 ports with RJ45 copper connectors v 100/1000 ports with mini-GBIC slots for MSA-compliant SFP transceivers v Optional 4-port 100/1000 MbE SFP module v Optional 4-port 10 GbE SFP+ module

IBM y-series 10/100/1000 BASE-T ports: The RJ45 ports operate at 10 Mbps or 100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. Because all ports support automatic MDI or MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. In addition, it is ideal and preferred to use straight-through cable for switch-to-switch connections.

Each of these ports supports auto-negotiation, so the optimum transmission mode (half or full duplex), and the data rate (10, 100, or 1000 Mbps) can be selected automatically. If a device connected to one of these ports does not support auto-negotiation, the communication mode of the port can be configured manually.

Combination ports: The y-series devices can contain four combination ports, which are four Small Form Factor Pluggable (SFP) network interfaces (1F~4F) that are shared with four of the RJ45 ports (ports 1~4). In the default configuration, if an SFP transceiver is installed in a slot and has a valid link on its port, the associated RJ45 port is disabled and cannot be used. The switch can also be configured to force the use of a combination RJ45 port or SFP slot, as required.

Note: The 4002-Y2A, Y4A, Y2C, and Y4C devices do not ship with SFP ports. You

can install an optional 4-port 10/100/1000 MbE SFP module which operate as combination ports, or an optional 4-port 10 GbE SFP+ module which

4 Ethernet y-series Installation and User Guide: Installation and User Guide

operates as uplinks to support optical connectivity. The 4002-Y2B and 4002-Y4B models contain four combination ports on the base device.

Note: The two left ports (ports <stack id>/2/1 and <stack id>/2/2) on the

four-port 10 Gbps SFP+ module do not pass regular Ethernet traffic by default. If you want all four ports on the four-port 10 Gbps SFP+ module to pass regular traffic, the global CLI command, stack disable, must be configured on the device to disable stacking. For more information, see the FastIron Configuration Guide.

16/10 Gbps Ethernet CX4 stacking ports

The 4002-Y2B and 4002-Y4B devices include two 16/10 Gbps Ethernet CX4 ports on the rear panel. The device can perform data transmission directly through copper links of up to 3 meters.

These CX4 ports are configured by default as 16 Gbps stacking ports which can connect to other 4002-Y2B and 4002-Y4B devices in a stack of up to eight members. Stacking simplifies deployment, management, and allows for data traffic to traverse over these high-speed stack links. The CX4 ports can also be configured to operate as 10 Gbps Ethernet ports by either disabling stacking on the device (stack disable) or configuring other ports to be the default stack ports (default-ports), and then setting the speed-duplex settings to 10 Gbps (speed-duplex). See the FastIron Configuration Guide for additional details on stacking and configuration.

The Up Link and Down Link LEDs on the front panel indicate operational status. If the Up Link or Down Link LED is on, the port is connected. If the Up Link or Down Link LED is off, no connection exists, or the link is down.

Chapter 1. Product overview 7

Cable specifications for CX4 stacking ports: The following cable specifications apply to the CX4 stacking ports:

v Support for 802.3ak or 10 Gbps Ethernet CX4 standard and 16 Gbps inter-unit

Power supplies

The y-series switches have two power receptacles on the rear panel. Each device ships with one power supply unit (PSU) installed. The 4002-Y2A, Y4A, Y2C, and Y4C devices use a 210W PSU. The 4002-Y2B and 4002-Y4B devices use a 620W PSU.

Note: The 4002-Y2A and 4002-Y4A power supplies have an arrow with an "E" to

indicate airflow from port side to non-port side (front to back). The 4002-Y2C and 4002-Y4C power supplies have an arrow with an "I" to indicate airflow from non-port side to port side (back to front). These power supplies must be matched with fan trays that also have the same corresponding "E" and "I" arrows on them (see Table 2 on page 3).

Each power supply has one standard (IEC-C14 inlet) power receptacle for the AC power cable, and AC and DC status LEDs for easy monitoring and troubleshooting.

Connecting devices in a stack

4002-Y2B and 4002-Y4B devices

Figure 22 on page 20 shows how the stack cables are connected between switches in a stack. The connection is based on 16/10 Gbps Ethernet, using CX4 cables. y-series devices support linear and ring stack topologies and can also operate as standalone devices.

In a linear stack topology there is a single stack cable connection between each switch that carries two-way communications across the stack. In ring stack topology, an extra cable is connected between the top and bottom switches forming a "ring" or "closed-loop." The closed-loop cable provides a redundant path for the stack link, so if one link fails, stack communications can be maintained. Figure 22 on page 20 illustrates a ring-topology stacking configuration.

You can form a stack containing up to eight y-series units. To connect switches in a stack, do the following steps:

1. Plug one end of a stack cable into one of the CX4 stacking ports of the top unit.

2. Plug the other end of the stack cable into one of the stacking ports of the next

unit.

3. Repeat steps 1 and 2 for each unit in the stack. Form a simple chain starting with a stacking port on the top unit and ending at a stacking port on the bottom unit (stacking up to eight units).

4. To form a ring stack topology, plug one end of a stack cable into the remaining stacking port on the bottom unit and the other end into the remaining stacking port on the top unit.

Chapter 2. Installing a y-series switch 19

Figure 22. Connecting switches in linear (top) and ring (bottom) topology stacks

5. One device in the stack will operate as the Active Controller, one will operate as Standby Controller, with the rest of the units operating as stack members. For information about how to configure your stack, see the FastIron Configuration Guide.

4002-Y2A, Y4A, Y2C, and Y4C devices

Figure 23 on page 21 and Figure 24 on page 21 show how stacking cables are connected between 4002-Y2A, Y4A, Y2C, and Y4C devices in a stack. The connection is based on 10 Gbps SFP+ using LC-LC MM fiber cables. These devices support linear and ring stack topologies with the optional SFP+ modules installed, and can also operate in standalone mode.

Note: 4002-Y2A, Y4A, Y2C, and Y4C devices must have a 4-port 10 Gbps SFP+

module (optional) installed to operate in a stack.

You can form a stack containing up to 4002-Y2A, Y4A, Y2C, and Y4C units. The first two ports on the 4-port 10 GbE SFP+ module are pre-configured to support stacking.

Note: If you want to use all four ports on the four-port 10 Gbps SFP+ module to

pass regular traffic the global CLI command, stack disable, must be configured on the device to disable stacking.

nety026

To connect switches in a stack, complete the following steps:

20 Ethernet y-series Installation and User Guide: Installation and User Guide

1. Plug one end of an LC-LC MM fiber cable into one of the SFP+ stacking ports of the top unit.

2. Plug the other end of the cable into one of the stacking ports of the next unit.

3. Repeat steps 1 and 2 for each unit in the stack. Form a simple chain starting

with a stacking port on the top unit and ending at a stacking port on the bottom unit (stacking up to eight units). See Figure 23.

4. (Optional) To form a ring stack topology, plug one end of an LC-LC MM Fiber cable into the remaining stacking port on the bottom unit and the other end into the remaining stacking port on the top unit. See Figure 24.

Use the following procedure to install an optional module into the switch.

1. Power off the device by removing all power cords connected to the power supplies.

2. Remove the blank metal plate (or a previously installed module) from the slot by removing the two screws with a Phillips #2 screwdriver.

3. Before opening the package that contains the module, touch the bag to the switch casing to discharge any potential static electricity. Using an ESD wrist strap during installation is recommended.

4. Remove the module from the antistatic shielded bag.

5. Holding the module level, guide it into the carrier rails on each side and gently

push it all the way into the slot, ensuring that it firmly engages with the connector.

6. When you are sure the module has properly engaged the connector, tighten the retainer screws to secure the module in the slot.

7. Power on the switch by plugging in the power cords into the power supplies. When the switch is powered on, the LEDs will follow the LED status as described in “Port, system, and power status LEDs for the 4002-Y2B and 4002-Y4B” on page 8.

Attention: If you do not install a module in a slot, you must keep the slot panel in place. If you run the device with an uncovered slot, the system will overheat.

Installing an optional module on the 4002-Y2A, Y4A, Y2C, and Y4C

The 4002-Y2A, Y4A, Y2C, and Y4C switches support an optional four-port 100/1000 Mbps SFP module or four-port 10 Gbps SFP+ module. The 10 Gbps SFP+ module allows you to use your device in a stack. Figure 30 shows how to install an optional SFP or SFP+ module.

nety034

Figure 30. Installing an optional module on the 4002-Y2A, Y4A, Y2C, and Y4C

Attention: The optional SFP and SFP+ modules are not hot-swappable. Be sure to power-down your device before you install or replace a module.

Use the following procedure to install an optional module into the switch.

1. Remove the blank metal plate (or a previously installed module) from the slot by removing the two screws with a Phillips #2 screwdriver.

2. Before opening the module package, touch the bag to the switch casing to discharge any static electricity. Using an ESD wrist strap during installation is recommended.

3. Remove the module from the antistatic shielded bag.

4. Hold the module level, guide it into the carrier rails and gently push it into the

slot until it firmly engages with the connector.

5. When the module is engaged, tighten the retainer screws to secure the module in the slot.

6. Power on the switch by plugging in the power cords into the power supplies. When the switch is powered on, the LEDs will follow the LED status as described in “Port, system, and power status LEDs for the 4002-Y2A, Y4A, Y2C, and Y4C” on page 10.

Note: The two left ports (ports <stack id>/2/1 and <stack id>/2/2) on the

four-port 10 Gbps SFP+ module do not pass regular Ethernet traffic by default. If you want all four ports on the four-port 10 Gbps SFP+ module to pass regular traffic the global CLI command, stack disable, must be configured on the device to disable stacking. For more information, see the FastIron Configuration Guide.

Attention: If you do not install a module in a slot, you must keep the slot panel in place. If you run the device with an uncovered slot, the system will overheat.

Chapter 2. Installing a y-series switch 27

28 Ethernet y-series Installation and User Guide: Installation and User Guide

Chapter 3. Checking network devices and testing connectivity

The procedures in this chapter are for qualified system administrators and users.

Assigning permanent passwords

By default, the CLI is not protected by passwords. To secure CLI access, it is strongly recommended that you assign passwords. See the FastIron Configuration Guide.

Note: You cannot assign a password using the Web management interface. 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:

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.

Privileged EXEC

This level is also called the Enable level and can be secured by a password. You can perform tasks such as manage files on the flash module, save the system configuration to flash, and clear caches at this level.

CONFIG

The configuration level. This level lets you configure the system IP address and configure switching and routing features. To access the CONFIG mode, you must already be logged into the Privileged level of the EXEC mode.

You can set the following levels of Enable passwords:

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.

Port Configuration

Allows read-and-write access for specific ports but not for global (system-wide) parameters.

Read Only

Allows access to the Privileged EXEC mode and CONFIG mode but only with read access.

Setting passwords

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

FCX648SHPOE Switch> enable

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

FCX648SHPOE Switch# configure terminal FCX624 Router(config)#

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

FCX648SHPOE Switch(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:

FCX648SHPOE Switch(config)# enable port-config-password <text> FCX648SHPOE Switch(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.

Use the following procedure to recover from a lost password.

1. Start a CLI session over the serial interface to the y-series 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.

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.

y-series devices support both classical IP network masks (Class A, B, and C subnet masks, and so on) and Classless Interdomain Routing (CIDR) network prefix masks.

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

example, enter “209.157.22.99 255.255.255.0” for an IP address with a Class-C subnet mask.

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 “209.157.22.99/24” for an IP address that has a network mask with 24 significant (“mask”) bits.

30 Ethernet y-series Installation and User Guide: Installation and User Guide

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. See the FastIron Configuration Guide.

Devices running Layer 2 software

Use the following procedure to configure an IP Address on a device running Layer 2 software.

1. At the opening CLI prompt, enter enable.

FCX648SHPOE Switch> enable

2. Access the configuration level of the CLI by entering the following command:

FCX648SHPOE Switch# configure terminal (Privileged EXEC Level) FCX648SHPOE Switch(config)# (Global CONFIG Level)

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

FCX648SHPOE Switch(config)# ip address 192.22.3.44 255.255.255.0

4. Set a default gateway address for the switch.

FCX648SHPOE Switch(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>

Devices running Layer 3 software

Before attaching equipment to a y-series Layer 3 Switch, you must assign an interface IP address to the subnet on which the router will be located. You must use the serial connection to assign the first IP address. For subsequent addresses, you also can use the CLI through Telnet or the Web management interface.

By default, you can configure up to 24 IP interfaces on each port, virtual interface, and loopback interface. You can increase this amount to up to 64 IP subnet addresses per port by increasing the size of the subnet-per-interface table.

The following procedure shows how to add an IP address and mask to a router port.

1. At the opening CLI prompt, enter enable.

FCX624 Router> enable

2. Access the configuration level of the CLI by entering the following command:

FCX624 Router# configure terminal Privileged EXEC Level FCX624 Router(config)# Global CONFIG Level

3. Configure the IP addresses and mask addresses for the interfaces on the router.

FCX624 Router(config)# int e 2 FCX624 Router(config-if-e1000-2)# ip address 192.22.3.44 255.255.255.0

Note: You can use the syntax ip address <ip-addr>/<mask-bits> if you know the

subnet mask length. In the above example, you could enter ip address

192.22.3.44/24.

Chapter 3. Checking network devices and testing connectivity 31

Syntax: enable [<password>] Syntax: configure terminal Syntax: [no] ip address <ip-addr> <ip-mask> [secondary]

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

Use the secondary parameter if you have already configured an IP address within the same subnet on the interface.

Configuring IP parameters for devices running Layer 3 software

This section describes how to configure IP parameters for devices running Layer 3 software.

Configuring IP addresses: You can configure an IP address on the following types of Layer 3 switch interfaces:

v Ethernet port v Virtual routing interface (also called a Virtual Ethernet or “VE”) v Loopback interface

By default, you can have up to 24 IP addresses on each interface except the out-of-band management port, but you can increase this number to 128 IP addresses.

Note: Once you configure a virtual routing interface on a VLAN, you cannot

configure Layer 3 interface parameters on individual ports in the VLAN. Instead, you must configure the parameters on the virtual routing interface itself.

y-series devices support both classical IP network masks (Class A, B, and C subnet masks, and so on) and Classless Interdomain Routing (CIDR) network prefix masks.

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

example, enter “209.157.22.99 255.255.255.0” for an IP address with a Class-C subnet mask.

v To enter a prefix network mask, enter a forward slash(/)andthenumber of

bits in the mask immediately after the IP address. For example, enter “209.157.22.99/24” for an IP address that has a network mask with 24 significant bits (ones).

By default, the CLI displays network masks in classical IP address format (for example: 255.255.255.0). You can change the display to prefix format.

Assigning an IP address to an Ethernet port: Enter the following commands to assign an IP address to port 1/1/1.

FCX624 Router(config)# interface ethernet 1/1/1 FCX624 Router(config-if-1/1/1)# ip address 192.45.6.1 255.255.255.0

Note: You also can enter the IP address and mask in CIDR format, as follows:

FCX624 Router(config-if-1/1/1)# ip address 192.45.6.1/24 Syntax: [no] ip address <ip-addr> <ip-mask>

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

32 Ethernet y-series Installation and User Guide: Installation and User Guide

Assigning an IP address to a loopback interface: Loopback interfaces are always

up, regardless of the states of physical interfaces. They can add stability to the network because they are not subject to route flap problems that can occur due to unstable links between a Layer 3 Switch and other devices. You can configure up to four loopback interfaces on a Layer 3 switch.

You can add up to 24 IP addresses to each loopback interface.

Note: If you configure the y-series switch to use a loopback interface to

communicate with a BGP4 neighbor, you must also configure a loopback interface on the neighbor and configure the neighbor to use that loopback interface to communicate with the y-series switch.

To add a loopback interface, enter commands such as those shown in the following example:

FCX624 Router(config)# exit FCX624 Router(config)# int loopback 1 FCX624 Router(config-lbif-1)# ip address 10.0.0.1/24 Syntax: interface loopback <num>

The <num> parameter specifies the virtual interface number. You can specify from 1 to the maximum number of virtual interfaces supported on the device. To display the maximum number of virtual interfaces supported on the device, enter the show default values command. The maximum is listed in the System Parameters section, in the Current column of the virtual-interface row.

Assigning an IP address to a virtual routing interface: A virtual interface is a logical port associated with a Layer 3 Virtual LAN (VLAN) configured on a Layer 3 switch. You can configure routing parameters on the virtual interface to enable the Layer 3 switch to route protocol traffic from one Layer 3 VLAN to the other, without using an external router.

This section describes how to configure an IP address on a virtual interface.

Note: The switch uses the lowest MAC address on the device (the MAC address of

port 1 or 1/1/1) as the MAC address for all ports within all virtual interfaces you configure on the device.

Enter commands similar to the following to add a virtual interface to a VLAN and configure an IP address on the interface.

FCX624 Router(config)# vlan 2 name IP-Subnet_1.1.2.1/24 FCX624 Router(config-vlan-2)# untag 1/1/1 to 1/1/4 FCX624 Router(config-vlan-2)# router-interface ve1 FCX624 Router(config-vlan-2)# interface ve1 FCX624 Router(config-vif-1)# ip address 1.1.2.1/24

The first two commands in this example create a Layer 3 protocol-based VLAN name “IP-Subnet_1.1.2.1/24” and add a range of untagged ports to the VLAN. The router-interface command creates virtual interface 1 as the routing interface for the VLAN. The last two commands change to the interface configuration level for the virtual interface and assign an IP address to the interface.

Syntax: router-interface ve <num> Syntax: interface ve <num>

Deleting an IP address

Enter a command similar to the following to delete an IP address.

FCX624 Router(config-if-1/1/1)# no ip address 1.1.2.1

Chapter 3. Checking network devices and testing connectivity 33

This command deletes IP address 1.1.2.1. You do not need to enter the subnet mask.

To delete all IP addresses from an interface, enter the following command:

FCX624 Router(config-if-1/1/1)# no ip address * Syntax: no ip address <ip-addr> | *

Connecting network devices

y-series devices support connections to other vendors' routers, switches, and hubs, as well other IBM devices.

Connectors

For port pinouts, refer to “Pinouts and signaling” on page 52.

Cable specifications

Refer to “Cable specifications” on page 53 for cable lengths and types.

Connecting to Ethernet or fast Ethernet hubs

For copper connections to Ethernet hubs, a 10/100BaseTX or 1000BaseT switch, or another device, a crossover cable is required. SeeFigure 31. If the hub is equipped with an uplink port, it will require a straight-through cable instead of a crossover cable. See Figure 32 on page 35.

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

negotiation of the connection between two 1000Base-T ports. In this case a straight-through cable may work just as well as a crossover cable. For more information about this feature, see the FastIron Configuration Guide.

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 Mbps Ethernet Copper ports on the devices support automatic Media Dependent Interface (MDI) and Media Dependent Interface Crossover (MDIX) detection. This feature is enabled on all 10/100 and 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.

net_com011

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

Connecting a network device to a fiber port

For direct attachment from the device to a Gbps NIC, switch, or router, using a fiber optic transceiver, you will need fiber cabling with an LC connector.

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

v Install a fiber optic transceiver (XFP, SFP, or SFP+) v Cable the fiber optic transceiver

The following sections describe these tasks.

Fiber Optic transceivers

Table 18 lists supported XFP transceivers (for stacking and non-stacking y-series models). Table 19 on page 36 shows supported SFP and SFP+ transceivers. For information about cabling for transceivers, see Table 28 on page 53.

10GSFPP-LR 10km No

Note: Distances supported on -SR optics depends on type of multi-mode fiber

cabling used. OM3, 50 micometer (2000 MHz*km) fiber is required to support maximum distances.

Installing a transceiver

You can install a new transceiver in an XFP, SFP, or SFP+ slot while the device is powered on and running.

While installing a transceiver, wear an ESD wrist strap with a plug for connection to a metal surface.

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

resistor.

CAUTION: Data processing environments can contain equipment transmitting on system links with laser modules that operate at greater than Class 1 power levels. For this reason, never look into the end of an optical fiber cable or open receptacle. (C027)

Use the following steps to install a transceiver.

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 transceiver from the protective packaging.

3. Gently insert the transceiver into the slot until it clicks into place. Transceivers

are keyed to prevent incorrect insertion.

Cabling a fiber optic transceiver

Use the following steps to cable a fiber optic transceiver.

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

2. Before cabling a fiber optic transceiver, it is strongly recommended that you clean the cable connectors and the port connectors. For more information, refer to “Cleaning the fiber optic connectors.”

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

4. Observe the link and active LEDs to determine if the network connections are functioning properly. For more information about the LED indicators, refer to Table 20 on page 38.

Cleaning the fiber optic connectors

To avoid problems with the connection between the fiber optic transceiver (SFP, SFP+, or mini-GBIC) and the fiber cable connectors, it is strongly recommended that you clean both connectors each time you disconnect and reconnect them. Dust can accumulate in the connectors and cause problems such as reducing the optic launch power.

Chapter 3. Checking network devices and testing connectivity 37

To clean the fiber cable connectors, it is recommended that you use a fiber optic reel-type cleaner. You can purchase this type of cleaner from the following Web site:

http://www.fisfiber.com/Home_Page.asp

When not using an SFP connector, make sure to keep the protective covering in place.

Testing connectivity

Test for connectivity by observing the LEDs related to network connection.

Pinging an IP address

To verify that a y-series device can reach another device through the network, enter a command similar to the following at any level of the CLI.

FCX648SHPOE Switch> ping 192.33.4.7

Syntax: ping <ip addr> [source <ip addr>] [count <num>] [timeout <msec>] [ttl <num>] [verify] [no-fragment] [quiet] [data <1-to-4 byte hex#, e.g. abcdef00>] [numeric] [size <byte>] [brief [max-print-per-sec <num 0-2047>]]

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

four responses.

Observing LEDs

After you install the network cables, you can observe certain LEDs to determine if the network connections are functioning properly. Table 20 outlines the LEDs related to the 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. For the locations of the LEDs, see “Control features” on page 3.

Tracing a route

To determine the path through which a y-series device can reach another device, enter a command similar to the following at any level of the CLI on the device.

FCX648SHPOE Switch> 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 y-series device displays up to two responses by default.

Troubleshooting network connections

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

connected device) are snug.

40 Ethernet y-series Installation and User Guide: Installation and User Guide

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 Use the CLI to verify that the port has not been disabled through a

configuration change. If you have configured an IP address on the device, you also can use the Web management interface or IronView Network Manager.

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

different cable.

Using Virtual Cable Testing to diagnose a cable

These devices support Virtual Cable Test (VCT) technology. VCT technology enables you to diagnose a conductor (wire or cable) by sending a pulsed signal into the conductor, then examining the reflection of that pulse. This method of cable analysis is referred to as Time Domain Reflectometry (TDR). By examining the reflection, the device can detect and report cable statistics such as local and remote link pair, cable length, and link status.

Configuration notes

v This feature is supported on copper ports only. It is not supported on fiber ports. v The port to which the cable is connected must be enabled when you issue the

command to diagnose the cable. If the port is disabled, the command is rejected.

v If the port is operating at 100 Mbps half-duplex, the TDR test on one pair will

fail.

v If the remote pair is set to forced 100 Mbps, any change in MDI or MDIX may

cause the device to interpret the Multilevel Threshold-3 (MLT-3) as a reflected pulse, in which case, the device will report a faulty condition. In this case, it is recommended that you run the TDR test a few times for accurate results.

To diagnose a cable using TDR, enter a command such as the following at the Privileged EXEC level of the CLI.

FCX648SHPOE Switch# phy cable-diag tdr 1/1/1

This command diagnoses the cable attached to port 1/1/1.

Syntax: phy cable-diag tdr <port-num>

Viewing the results of the cable analysis

To display the results of the cable analysis, enter a command similar to the following at the Privileged EXEC level of the CLI.

FCX648SHPOE Switch# show cable-diag tdr 1/1/1 Syntax: show cable-diag tdr <port-num>

Pair status The status of the link. This field displays one of the following:

v Terminated: The link is up. v Shorted: A short is detected in the cable. v Open: An opening is detected in the cable. v ImpedMis: The impedance is mismatched. v Failed: The TDR test failed.

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 XFP, SFP, and SFP+ manufacturer's recommended thresholds. For more information about digital optical monitoring, refer to FastIron Configuration Guide.

Managing temperature settings

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

Using the temperature sensor

The device ships with three built-in temperature sensors that cause the device to generate a Syslog message and SNMP trap if the temperature exceeds a specified warning level or shutdown level. If the device temperature exceeds the safe threshold (shutdown level), the device will reboot.

The software reads the temperature sensors based on the device poll time, which is by default 60 seconds. If the temperature equals or exceeds the shutdown temperature for five consecutive polls by the software, the software will reboot the device to prevent damage.

You can use the CLI or Web management interface to perform the following tasks:

v Display the temperature of the device v Change the warning and shutdown temperature levels v Change the device poll time

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.
