Figure 2: Single-Site Repeater Configuration 1

If the distance between the first non-colocated base radio and subsequent non-colocated base radios
is less than 328 ft (100 m), a single Ethernet LAN switch can be used to distribute the site controllers
call control signaling to those non-colocated base radios. The stated distance limit for a shielded
twisted pair Ethernet cable (CAT5) is 328 ft (100 m) before the signal degrades too much to be used.
See Figure 3: Single Site Repeater Configuration 2 on page 33.

Once the site controller link is extended, the control plane could be open to access from elements
other than the base radios. Each Ethernet LAN switch must be manually configured to provide MAC
Port lockdown to make sure that only the proper devices can communicate with each other. MAC Port
lockdown may also be applied on any unused Expansion Ports on the site controller. See the MAC
Port Lockdown manual to lock down the site controller. The switch ports may be enabled or disabled
according to specific security guidelines. See "Enabling/Disabling Ports on HP Switches Using Local
Access" in the System LAN Switches manual.
