hole on the Altitude 300-2 should line up with the lock hasp hole on the universal mounting bracket
when the unit is slid all the way forward (Figure 5).
3Lock and secure the Altitude 300-2. The Altitude 300-2 and the universal mounting bracket are
designed to use a Master Lock 120T or similarly sized padlock to secure the wireless port from theft
or removal from the bracket (Figure 5).
WARNING!
The Altitude 300-2 is not secured to the bracket unless a padlock is used. If a padlock is not used the
unit should be secured to the bracket by a cable tie through the lock hasp to keep it from falling. Failure
to secure the unit is hazardous.
4For wall and ceiling installations skip this step. For table and shelf installations, attach the stick-on
feet. The Altitude 300-2 kit comes with four stick-on feet for use when the unit is installed on top of
a table or shelf. The feet are not needed for wall and ceiling installations.
WARNING!
The stick-on feet have not been tested for use in a plenum space. Do not use them for
above-the-ceiling installations.
5Connect the Ethernet cable to the Altitude 300-2 and to a powered, 10/100BaseT Ethernet cable from
a Summit 300-48.
NOTE
While the Altitude 300-2 uses standard 10/100BaseT signals and PoE power, it should only be
connected to a Summit 300-48 port for the proper operation of the management and configuration
features of the Extreme Networks Unified Access System.
6(Optional) Connect the computer cable lock. If the universal mounting bracket is not used, the
Altitude 300-2 can be locked with a computer cable. The unit has a standard computer cable lock
hole located at the rear of the box (Figure 1).
7For the Altitude 300-2i skip to step 8. For the Altitude 300-2d, connect the external antennas
(Figure 2). The unit should be located within the reach of the antenna cables. The large RP-TNC
connectors are used for 2.4 GHz 802.11b/g antennas and the small RP-SMA connectors are used for 5
GHz 802.11a antennas. Two connectors of each type are supplied to support antenna diversity. When
this step is completed, go to step 10.
8Attach the antenna shrouds (Altitude 300-2i). If the plastic cover is to be used, attach the antenna
shrouds to the antennas (Figure 8).
9Adjust the Integrated antennas, Altitude 300-2i. The Altitude 300-2i is equipped with two integrated
dual band antennas that connect to both the 802.11a and 802.11b/g radios. Selecting the proper angle
for the antennas is important to achieve the best performance from the system. For this reason the
Altitude 300-2i is equipped with antennas that can be rotated. Once the proper angle has been set,
the Altitude 300-2i is outfitted with antenna shrouds that work with the plastic cover to lock in the
proper angle. This prevents the antennas from being accidentally misaligned after installation.
10 (Optional) Attach the optional plastic cover to the box (Figure 9). After the cover has been secured,
push on each antenna to make sure its shroud is locked in position. This ensures that the teeth on
the shroud are engaged with the teeth on the cover.

The best location for the Altitude 300-2 is at the center of the wireless coverage area within line of sight
of as many wireless devices as possible. In general, the higher the wireless port is placed, the better the
overall performance. The Altitude 300-2 and its mounting hardware are designed for installation in a
variety of places inside a building. Select the installation site to conform to RF performance, aesthetics,
convenience criteria.
WARNING!
The Altitude 300-2 must be used in settings that meet the environmental specifications. It is not
designed for outdoor use.
Mounting Below a Hard Ceiling
The Altitude 300-2 can be installed underneath a hard ceiling with wall anchors used to mount the
bracket.
Select the orientation for the bracket, keeping in mind that the integrated antennas are on the side and
to the back of the Altitude 300-2i. Use the bracket as a template to mark the holes on the ceiling. For
each of the four plastic anchors supplied with the unit, drill 4.8 mm (3/16”} pilot holes, 24.5 mm (1”)
deep. If wall anchors are not being used drill 3.2 mm (1/8”) holes, 25.4 mm (1”) deep. Install the bracket
using the screws from the kit. The Altitude 300-2 is designed to slip into the mounting slots on the
bracket and slide all the way to the front, (Figure 5). The unit should be secured with a padlock (not

antenna adjustments are made and the unit is locked or secured.tegrated antennas, and the plastic
cover.
WARNING!
The Altitude 300-2 is not secured to the bracket unless a padlock is used. If a padlock is not used the
unit should be secured to the bracket by a cable tie through the lock hasp.
Mounting Below a Hanging Ceiling
The Altitude 300-2 can be suspended from the T-bars of a hanging ceiling. The mounting kit contains
two T-bar fasteners that can be adjusted for a variety of T-bar widths. The round holes on the bracket
can be used for the T-bar fasteners. Orient the bracket on the T-bar so that the antennas face the desired
direction. Use the bracket to lightly mark where the T-bar fasteners should be placed. Install the two
T-bar fasteners on the T-bar, see Figure 6. Some ceilings have ceiling tiles that hang down below the
bottom of the T-bar. Spacers are provided with the kit for these types of tiles. The spacers should be
placed between the T-bar fasteners and the bracket with the spacer face against the bracket (Figure 7).
Mount the bracket and confirm that the fasteners are tight and the bracket is secure. You can now slip
the Altitude 300-2 into the bracket mounting slots and slide it to the back (Figure 5). Secure the unit
with a padlock (not supplied) or a cable tie (supplied). Follow standard procedures for connecting the
Ethernet cable, antenna shrouds for integrated antennas, and the plastic cover.
