Choose A Suitable Location - Xirrus X2120 Quick Installation Manual


All Xirrus XD2 APs are Type 2, Class 4 POE-802.3at devices. If your switch vendor provides a setting for
the type of powered-device detection with options such as Legacy, 4-Point, or BOTH, set the port to BOTH
or 4-Point. Do not use settings intended for legacy devices.

Access to a Web browser to configure the AP via the Xirrus Management System or directly via the AP's
Windows Management Interface (WMI).

For a suspended ceiling mount, you need a 7/16" nut driver to attach the mounting plate to the T-Bar clips.
(See "Install Mounting Hardware and AP" on page 3.) Do not use old T-bar clips or studs from XN or XS APs
with the X2 and XD2 Series—they will damage the AP case.

For a locked installation, supply a zip-tie, small lock, or other locking hardware.
NOTE: Leave protective plastic film on the AP until installation is complete, to avoid leaving marks on the AP.
Mounting Options

Direct Ceiling Mount—for the ability to lock the AP in place or detect tampering, use the furnished mounting
plate with at least two user-supplied screws.

Choose a Suitable Location


Choose an indoor location that is central to your users, that is away from heat sources. To ensure good air flow,
it is essential that the AP's vents are not blocked.

The AP should be installed parallel to the ground (i.e., in a horizontal position, not tilted on its side). The AP
should not be more than 30 feet above the ground (or the level at which receiving devices will be used). For
atypical installations, please verify the resulting signal coverage.

The location must be capable of supporting the weight of the AP and the mounting bracket (about 2 lb total).

For optimal placement, we recommend that a predictive survey be performed by a qualified Xirrus partner.

Maintain a distance of at least 50 feet between additional APs.

Keep the unit away from electrical devices or appliances that generate RF noise-at least 3 to 6 ft (1m - 2m).
