Wireless LAN ArrayInstalling the Xirrus Array 43Important Notes About Network ConnectionsRead the following notes before making any network connections.Mounting the UnitMost offices have drop-down acoustical ceiling tiles set into a standard grid. TheXirrus Array has been designed to enable mounting to a tiled ceiling via amounting plate and clamps that attach to the grid. Once the mounting plate isattached, the Array simply rotates onto the plate (similar to a smoke detector).Once the unit is mounted it can be removed and re-attached easily, without theneed for tools or modifications to the original installation.This section assumes that you are mounting the Array to a tiled ceiling. If yourceiling is not tiled, the mounting plate can be attached directly to the ceiling withthe screws and anchors provided (without using the tile grid mounting clamps).! The Array’s Ethernet ports should be plugged into an Ethernet switch, not anEthernet hub—if a hub is used, we recommend that you connect only oneEthernet port.! The Gigabit1 Ethernet interface is the primary port for both data andmanagement traffic. If a single Ethernet connection is used, it must beconnected to the Gigabit1 Ethernet interface.The 10/100 Ethernet Port can be used for managing the Array, and will onlybridge management traffic. See also, “Port Failover Protection” on page 33.# When the unit’s IP address is unknown or a network connection has not beenestablished, the serial cable is used for connecting directly with the CommandLine Interface (CLI) via HyperTerminal. When a network connection isestablished, the Array can be managed from any of the available networkconnections, either Fast Ethernet, Gigabit 1 or Gigabit 2.
