Cisco Aironet 1250 Series Access Point Hardware Installation Guide
OL-8247-03
Chapter 1 Overview
Hardware Features
Console Port
The console port is located on the bottom of the unit in the access point connector area (see
Figure 1-3
).
The console port provides access to the access point’s command-line interface (CLI) using a terminal
emulator program. Use an RJ-45 to DB-9 serial cable to connect your computer’s COM port to the access
point’s serial console port. Assign the following port settings to a terminal emulator to open the
management system pages: 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control.
Note
After completing your configuration changes, you must remove the serial cable from the access point.
The serial cable can be purchased from Cisco (part number AIR-CONCAB1200) or can be built using
the pinouts in
Appendix E, “Console Cable Pinouts.”
Power Sources
The access point can receive power from a 1250 series DC power module or from inline power using the
Ethernet cable. The access point supports the IEEE 802.3af inline power standard and Cisco CDP Power
Negotiation. Using inline power, you do not need to run a power cord to the access point because power
is supplied over the Ethernet cable.
The access point supports the following power sources:
•
Cisco Aironet 1250 series DC power module (AIR-PWR-SPLY1)
•
Inline power:
–
Cisco Aironet 1250 series power injector (AIR-PWRINJ4)
–
IEEE 802.3af power source (access point with only one radio module installed)
Note
Current switches and patch panels do not provide enough power to operate the access point with both
2.4-GHz and 5-GHz radios. At power-up, if the access point is unable to determine that the power source
can supply sufficient power, the access point automatically deactivates both radios to prevent an
over-current condition. The access point also activates a Status LED low power error indication and
creates an error log entry (refer to the
“Checking the Autonomous Access Point LEDs” section on
page 3-2
or the
“Checking the Lightweight Access Point LEDs” section on page 4-3
).
UL 2043 Compliance
The access point has adequate fire resistance and low smoke-producing characteristics suitable for
operation in a building's environmental air space, such as above suspended ceilings, in accordance with
Section 300-22(c) of the NEC, and with Sections 2-128, 12-010(3) and 12-100 of the
Canadian
Electrical Code
, Part 1, C22.1.
Caution
The 1250 series power injector (AIR-PWRINJ4), the 1250 series DC power module
(AIR-PWR-SPLY1), and the antennas are not tested to UL 2043 and should not be placed in a building’s
environmental air space, such as above suspended ceilings.
