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

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

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

2. ESD-protective wrist strap

The installation site for the EXTREME 5120-24XT-4Y-AC-R 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, you should 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-R in a standard 19-inch equipment rack. The switch can be installed in a two-post rack or in a four-post rack using just the two front posts for forward mounting or two back posts for rear mounting. The rack mount kit supports flush-mounting and mid-mounting.

Follow these steps for a two-post mount:

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

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 5120-24XT-4Y-AC-R runs on AC power. To attach the switch to a power source, do the following:

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: Installing the system as described meets protective earth grounding requirements. 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 5120-24XT-4Y-AC-R. 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.

The front panel components include:

1. 1Gb/10Gb SFP+ ports (1Gb/10GBase-T non-PoE ports for 5120-24XT-4Y)

2. 10Gb/25Gb SFP28 ports
