2. Attach the two T-bar clips to the suspended ceiling T-bar at the desired mounting
position, either 9.2 cm (3 5/8 inches) or 13 cm (5 1/8 inches) apart on center.
3. Attach the bracket to the two T-bar clips, then secure each with a second nut.
4. Connect the Ethernet cable to the MSM422 Ethernet port.
5. Position the MSM422 against the bracket so that its feet are next to the retention tabs.
6. Slide the MSM422 so that the feet are held in place by the retention tabs.
7. Using the retention screw, secure the MSM422 to the bracket. Optionally, you also can
use a cable lock.
8. Verify that the MSM422 is firmly anchored before letting go of it.
Installing in a plenum
See Plenum installation on page 3-7.
Antenna position
The antenna flaps can be adjusted to optimize radio performance. Start with the following
positions, then adjust as needed. (See also the MSM422 Antenna Technical Note.)
For wall mount, close or fully open the flaps.
For ceiling mount, close the flaps or point them toward the floor (90
o
).
Powering the MSM422
The MSM422 can be powered by:
A 10/100 or 10/100/1000 PoE-enabled switch. PoE-enabled switches are available from HP.
An HP 1-Port Power Injector (J9407A).
An HP MSM422 Power Supply (J9406A).
Caution If the MSM422 will be powered by a user-supplied PoE power injector, use only a gigabit-
compatible power injector. PoE injectors designed for 10/100 networks only are NOT
compatible with the MSM422.
