Data Center Deployment

In many data center configurations, Ethernet connections link servers and data networks, and Fibre Channel connections link servers to storage networks. This switch enables the creation of a converged network, which employs lossless Ethernet connections between FCOE storage, servers, and other data network switches.

Figure 4: Converged Ethernet Data Center Deployment

Rack Cooling The top-of-rack switch is a high-performance, high-density unit that generates a

substantial amount of heat. When mounted in a rack with other equipment, it is important that the switch has the same airflow direction to avoid “hot loops” in the data center ailses. Hot loops increase cooling requirements since warm air is drawn into rack devices instead of cool air.

Most rack-mounted blade servers draw cool air from the front and expel hot air at the rear. The top-of-rack switch includes two fan trays that have a front-to-back (F2B) airflow direction that maintains cool ailses in the data center.

6. If installing multiple switches, repeat steps 1 to 4 to mount the switches

following your rack plan.

Switch Cooling Requirements

Wherever the switch is located, be sure to pay close attention to switch cooling requirements. The location should be well ventilated and provide unrestricted air flow at the front, back, and sides of the switch. If the air flow is insufficient, it may cause the switch to overheat and possibly fail.

The switch includes two removable fan trays located in the rear of the switch. The fan tray options may have either a front-to-back (F2B) airflow direction or a back-tofront (B2F) airflow direction. For proper switch cooling, all installed fan trays must have a matching airflow direction.

The following figure shows the airflow through the switch.

Figure 16: Switch Cooling

F2B Airflow B2F Airflow

Chapter 3

Switch Cooling Requirements

| Switch Chassis

Rack Cooling When mounting the switch in an enclosed rack or cabinet, be sure to check the

following guidelines to prevent overheating:

◆ Make sure that enough cool air can flow into the enclosure for the equipment it

contains.

◆ Check that the rack or cabinet allows the hot air to exit the enclosure (normally

from the top) without circulating back into equipment.

◆ If the enclosure has sides or doors with ventilation holes, make sure they are

not blocked by cables or other obstructions.

◆ Route cables within the rack or cabinet to maximize the air flow.

◆ When possible, do not completely fill the rack or cabinet with equipment, allow

some unused space within the enclosure for better air flow.

Fan Trays The fan trays are an important part of the switch air cooling system. Two fan trays

must be installed in the switch at all times. If a fan should fail, the entire fan tray must be replaced as soon as possible.

The fan trays used must have matching airflow direction. You must only install and use either two front-to-back airflow or two back-to-front airflow fan trays :

◆ AS4600-54TS-FANTRAY (front-to-back airflow)

◆ AS4600-54TSR-FANTRAY (back-to-front airflow)

The airflow direction of the fan tray is indicated by labels attached to the fan tray (see Figure 17 on page 29).

Caution:

All installed fan trays must have a matching airflow direction. Installing a front-to-back (F2B) tray with a back-to-front (B2F) fan tray may result in overheating and subsequent damage to the switch.

Each of the removable fan trays, located at the rear of the switch, include dual inline fans and support fan speed control. The fan speed is dynamically controlled as a function of temperature: the higher the internal temperature, the faster the speed of the fans. The fan trays do not include LED indicators.

4 Power and Grounding

This chapter focuses on the switch power supplies, how to install them, and how to power-on the switch. Connecting the switch to ground is also covered.

This chapter includes these sections:

◆ “Power Supply Units” on page 32

◆ “Grounding the Chassis” on page 34

◆ “How to Connect to AC Power” on page 35

Power Supply Units

The switch supports hot-swappable power supply units (PSUs). You can install up to two PSUs with matching airflow direction in the switch. When two PSUs are installed, the PSUs operate in a load-sharing mode and provide 1+1 redundancy.

Note:

1+1 redundancy is a system where a switch power supply is backed up by another switch power supply in a load-sharing mode. If one power supply fails, the other power supply takes over the full load of the switch.

The AC PSUs require power from an external AC power supply that can meet the requirements as listed in Table 2. A standard AC power socket is located on the rear panel of the PSU. The power socket is for the AC power cord.

Cable Labeling and Connection Records

When planning a network installation, it is essential to label the opposing ends of cables and to record where each cable is connected. Doing so will enable you to easily locate inter-connected devices, isolate faults and change your topology without need for unnecessary time consumption.

To best manage the physical implementations of your network, follow these guidelines:

◆ Clearly label the opposing ends of each cable.

◆ Using your building’s floor plans, draw a map of the location of all network-

connected equipment. For each piece of equipment, identify the devices to which it is connected.

◆ Note the length of each cable and the maximum cable length supported by the

switch ports.

Chapter 5

Cable Labeling and Connection Records

| Port Connections

◆ For ease of understanding, use a location-based key when assigning prefixes to

your cable labeling.

◆ Use sequential numbers for cables that originate from the same equipment.

◆ Differentiate between racks by naming accordingly.

◆ Label each separate piece of equipment.

◆ Display a copy of your equipment map, including keys to all abbreviations at

each equipment rack.

to be powered off before installing or removing a transceiver.

Note:

SFP/SFP+/QSFP+ transceivers are not provided in the switch package.

Transceiver slots used for 10G or 40G DAC connections are described in the

section “DAC Connections” on page 49.

To install an SFP/SFP+/QSFP+ transceiver, do the following:

1. Consider network and cabling requirements to select an appropriate

transceiver type that is also compatible with the switch transceiver support.

2. If the SFP/SFP+/QSFP+ slot is covered with a rubber protective cap, remove the

cap and keep it for later replacement.

3. Insert the transceiver with the optical connector facing outward and the slot

connector facing down. Note that SFP/SFP+/QSFP+ transceivers are keyed so they can only be installed in the correct orientation.

4. Slide the transceiver into the slot until it clicks into place. If you do not

immediately connect a cable to the port, use a rubber protective cap to keep the transceiver optics clean.

How to Connect to Twisted-Pair Copper Ports

The RJ-45 management port on the switch supports automatic MDI/MDI-X pinout configuration, so you can use standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).

The connection requires an unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable with RJ-45 connectors at both ends.

Assignments

To ensure proper operation when installing the switch into a network, make sure that the current cables are suitable for 10BASE-T, 100BASE-TX, or 1000BASE-T operation. Check the following criteria against the current installation of your network:

◆ Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables

with RJ-45 connectors; Category 5, 5e or better cable for 1000BASE-T connections, Category 5 or better for 100BASE-TX connections, and Category 3 or better for 10BASE-T connections.

◆ Protection from radio frequency interference emissions

◆ Electrical surge suppression

◆ Separation of electrical wires (switch related or other) and electromagnetic

fields from data based network wiring

◆ Safe connections with no damaged cables, connectors or shields

All 100BASE-TX RJ-45 ports support automatic MDI/MDI-X operation, so you can use straight-through or crossover cables for all network connections to PCs, switches, or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable.

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations, Category 5e (enhanced Category 5) or Category 6 cable should be used. The Category 5e and 6 specifications include test parameters that are only recommendations for Category 5. Therefore, the first step in preparing existing Category 5 cabling for running 1000BASE-T is a simple test of the cable installation to be sure that it complies with the IEEE 802.3-2008 standards.

Direct Attach Cable (DAC) is a method of connecting two SFP+/QSFP+ interfaces without using optics and fiber cable. A fixed length of twinax copper cable is terminated at each end with physically-compliant SFP+/QSFP+ transceivers that do not include all their normal electronic and optical components. The result is a low cost, low-latency, 10G/40G Ethernet solution for short distances, ideal for connections within the data center.

A 10G DAC connection is also known as twinax copper or 10GBASE-CR. DAC copper cables are available in pre-terminated lengths up to 7 m (22.9 ft).

For 40G DAC, or 40GBASE-CR4, copper cables are also available in pre-terminated lengths up to 7 m (22.9 ft).

Follow these steps to connect to the Console port:

1. Attach one end of the included RJ-45-to-DB-9 serial cable to a DB-9 COM port

connector on a management PC.

2. Attach the other end of the serial cable to the Console port on the switch.

3. Configure the PC’s COM port required settings using VT-100 terminal emulator

software (such as HyperTerminal) running on the management PC. The switch’s default console port settings are:

■

115200 bps, 8 characters, no parity, one stop bit, 8 data bits, and no flow control

4. Log in to the command-line interface (CLI) using default settings:

■

User—admin

■

Password—null (there is no default password)

For a detailed description of connecting to the console and using the switch’s command line interface (CLI), refer to the Administrator’s Guide.

How to Connect to the Mgmt Port

The port on the switch’s front panel labeled “Mgmt” provides an out-of-band network connection to the management agent of the switch using TCP/IP over Ethernet. You can access the switch from anywhere in the attached network using Telnet, a web browser, or other network management tools.

When using the switch’s command-line interface (CLI), the Mgmt port is identified as the "serviceport" and there is no default IP address. The "serviceport protocol" is set to DHCP enabled as default.

Note:

The management port provides direct TCP/IP over Ethernet access to the switch’s configuration. To prevent unauthorized access, it is recommended that it only be connected to a secure private network.

see the Administrator’s Guide.

2. Connect a management PC or network to the Mgmt port. (See “How to

Connect to Twisted-Pair Copper Ports” on page 41 for details.)

3. Use an appropriate software tool to access the switch management interface.

4. Log in using the default username and password.

System Self-Diagnostic Test Failure

If the Diag LED indicates a failure of the system power-on-self-test (POST), you can use a console connection to view the POST results. The POST results may indicate a failed component or help troubleshoot the problem. For more information on connecting to the console port and using the CLI, refer to the Administrator’s Guide.

Note a POST failure normally indicates a serious hardware fault that cannot be rectified or worked around. If you encounter a POST failure, you should contact your dealer for assistance.

Power and Cooling Problems

If a power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or PSU. However, if the switch powers off after running for a while, check for loose power connections, power losses or surges at the power outlet. If you still cannot isolate the problem, the PSU may be defective.

Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.

Chapter A

Power and Cooling Problems

| Troubleshooting

In-Band Access

You can access the management agent in the switch through a connection to any port using Telnet, a web browser, or other network management software tools. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then verify that you entered the correct IP address. Also, be sure the switch port has not been disabled. If it has not been disabled, then check the network cabling that runs between your remote location and the switch.

Note:

It is recommended that you use the out-of-band Management port as described in the section: “How to Connect to the Mgmt Port” on page 55.
