The AIR-WLC4112-K9, AIR-WLC4124-K9, and AIR-WLC4136-K9 Cisco 4100 Series Wireless
LAN Controllers contain Class 1 Lasers (Laser Klasse 1) according to EN 60825-1+A1+A2.
The Cisco 1000 Series lightweight access points with or without external antenna ports are only
intended for installation in Environment A as defined in IEEE 802.3af. All interconnected
equipment must be contained within the same building including the interconnected
equipment's associated LAN connections.
For Cisco 1000 Series lightweight access points provided with optional external antenna ports,
be sure that all external antennas and their associated wiring are located entirely indoors. Cisco
1000 Series lightweight access points and their optional external antennas are not suitable for
outdoor use.
Be sure that plenum-mounted Cisco 1000 Series lightweight access points are powered using
Power over Ethernet (PoE) to comply with safety regulations.
For Cisco Wireless LAN Controllers, verify that the ambient temperature remains between 0 to
40° C (32 to 104° F), taking into account the elevated temperatures when installed in a rack.
When multiple Cisco Wireless LAN Controllers are mounted in an equipment rack, be sure that
the power source is sufficiently rated to safety run all of the equipment in the rack.
Verify the integrity of the ground before installing Cisco Wireless LAN Controllers in an
equipment rack with other equipment.
