EXTREME 5120-44X-4Y-2C (01) PDF DOCUMENT

The necessary tools to set up the EXTREME 5120-44X-4Y-2C are:

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

2. ESD-protective wrist strap

The installation site for the EXTREME 5120-44X-4Y-2C 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 EXTREME 5120-44X-4Y-2C, 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.

The EXTREME 5120-44X-4Y-2C can be installed in a standard 19-inch equipment rack. The provided two-post mounting kit accommodates rack posts 3 inches or 6 inches wide and supports both flush- and mid-mounting.

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 rack-mounting screws and nuts that are appropriate for the rack (provided). The switch can be mounted to the two front posts or the two rear posts as shown.

The EXTREME 5120-44X-4Y-2C runs on AC power. To connect the switch to a primary power source:

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 hardware installation guide for troubleshooting information.

Note: Installing the system as described meets the protective earth grounding requirements of the National Electrical Code (NEC) UL 62368-1 and IEC 62368-1 standards. However, in some cases, it may be necessary to use an alternative grounding method. In these cases, a 14 AWG wire can be connected between the grounding lug on the chassis and a nearby building ground point.

Upgrade to a generally available (GA) version of the software before you use the EXTREME 5120-44X-4Y-2C. 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.

Each Extreme 5120 Series switch includes a Micro-B USB serial console port, an RJ-45 serial console port, a 100/1000BASE-T out-of-band management port, and a USB Type A storage port. 5120 Series switches are pre-loaded with the Switch Engine OS.

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

Warning: Extreme Networks 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.

Warning: This equipment is designed for installation in restricted access locations and suitable for installation in Information Technology Rooms in accordance with Article 645 of the National Electrical Code and NFPA 75, not suitable for use in locations where children are likely to be present.

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

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

Caution: 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.

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

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

Warning: 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.

Caution! Shock hazard! Disconnect all power inputs before servicing.

Warning: The battery should be replaced by service personnel only. The battery used must be a lithium battery of the correct type. Dispose of expended battery in accordance with local disposal regulations.
