EXTREME 5120-24XT-4Y-AC-F (01) PDF DOCUMENT

The following tools are needed to install the EXTREME 5120-24XT-4Y-AC-F switch:

1. A #2 Phillips screwdriver (a magnetic screwdriver is recommended).

2. An ESD-protective wrist strap.

The installation site for the EXTREME 5120-24XT-4Y-AC-F must meet the following requirements:

• Appropriately grounded power receptacles located within 1.8 m (6 ft.).

• A readily accessible device for disconnecting power, such as a breaker or master switch.

• Network cabling within reach.

• Ensure that the vent openings on the front panel and the rear fan modules are not blocked for proper ventilation.

• Temperature between 0°C (32°F) and 50°C (122°F), or as noted in “Operating Conditions”, with fluctuations of less than 10°C (18°F) per hour.

After unpacking the box for your EXTREME 5120-24XT-4Y-AC-F, verify that all of the following components are included:

1. Switch

2. Quick reference guide

3. Accessory box

4. Rack mount ears (2), accessory bag: Rail screws (12), rack screws (6), rack nuts (6)

Console cables can be ordered separately.

You can install the EXTREME 5120-24XT-4Y-AC-F switch in a standard 19-inch equipment rack. The rack mount kit supports flush-mounting and mid-mounting in a two-post rack.

1. Attach a mounting bracket to each side of the switch. You can attach the brackets at the front of the switch (front flush-mount or front mid-mount) or at the middle of the switch (rear flush-mount or rear mid-mount).

2. Secure the brackets to the rack posts using the provided rack-mounting screws and nuts that are appropriate for the rack. The switch can be mounted to the two front posts or the two rear posts.

The EXTREME 5120-24XT-4Y-AC-F runs on AC power. To connect the switch to a primary power source, follow these steps:

1. Connect the AC power cord to the AC power input socket on the power supply and an AC power outlet.

2. When power is connected, verify that the switch’s PWR LED turns green. If the PWR LED does not turn green, refer to the Extreme 5120 Hardware Installation Guide for troubleshooting information.

Note on grounding: In some cases, it may be necessary to use an alternative grounding method. A 14 AWG wire can be connected between the grounding lug on the chassis and a nearby building ground point.

You should upgrade to a generally available (GA) version of the software before you use the EXTREME 5120-24XT-4Y-AC-F. Switch Engine is the default operating system (OS) for the 5120 Series. To connect the switch to the network, upgrade it, and configure it for use, follow the steps in the Extreme 5120 Hardware Installation Guide.

Please observe the following safety notices when working with the EXTREME 5120-24XT-4Y-AC-F switch:

• Electrical Hazard: Only qualified instructed or skilled personnel should perform installation, repair, or disassembly procedures.

• Power Supplies: The power supplies do not have switches for turning the unit on and off. Before servicing, disconnect all power cords to remove power from the device. Make sure that these connections are easily accessible.

• Installation Location: This equipment is designed for installation in restricted access locations and suitable for installation in Information Technology Rooms, not suitable for use in locations where children are likely to be present.

• Circuit Breaker: A dedicated Listed circuit breaker rated at 15A is to be used for each power supply connection.

• Mounting: Before mounting the device, ensure that the rack can support it without compromising stability. Otherwise, personal injury or equipment damage may result.

• ESD: Follow appropriate ESD procedures when unpacking and handling the switch. These include unpacking the switch in an ESD-safe environment and wearing appropriate ESD protective gear, such as ESD-safe footwear and ESD wrist straps where appropriate.

• Indoor Use: This unit must be installed indoors. The unit, AC power adapter, and its cables are not designed for outdoor use.

• Radiation Exposure: Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

• Optical Safety: Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases eye hazard. Use only UL/CSA, IEC/EN60825-1/-2 recognized pluggable modules.

• Shock Hazard: Disconnect all power inputs before servicing.
