Install wiring
To install local are network (LAN) ethernet cable
LAN ethernet cabling is intended for high-speed communications between the CPU, the
switch and the access points.
1. Install unshielded twisted-pair (4 pair) cabling (Category 5 or 5E) between the CPU,
the switch and the access points.
Maximum cable distance between the CPU and the switch: 300 feet.
Maximum cable distance between the switch and each AP: 300 feet.
Minimum installation distance between APs: 6 feet. Maximum: 40 feet.
Minimum installation distance between AP/AP antennas: 2 feet.
2. Leave at least 15 feet of extra cable at the location where each AP is to be installed.
This allows you to adjust AP locations during network testing to enable you to identify
the best AP locations for communication with the monitors.
Do not install the AP mounting brackets. They will be installed later when the APs are
permanently installed.
3. Install a network terminal for the CPU.
To aid in troubleshooting, label network terminal ports for data cables that will be
plugged into the switch from the CPU and the APs.
4. Terminate the cabling per TIA/EIA-568 standards.
To install telephone/data cabling
Telephone/data cabling is intended for serial communication between the CPU and the
Welch Allyn Technical Support department, via an external modem.
1. Install dedicated, analog, stand-alone direct inward dial (DID) telephone line.
The line must not be controlled by the local PBX or switchboard or routed through the
telephone switchboard.
2. Terminate cabling with a standard telephone jack.
Caution All wiring must be installed in compliance with local and state safety
guidelines and the following instructions and specifications.
WARNING Do not install an access point or access point antenna closer than
two feet from any location where people frequent. Installation closer than two
feet could result in exposure to levels of radio frequency energy that are higher
than recommended by the Federal Communications Commission (FCC).
Installation above a nurses station is not acceptable.
