Chapter 3: Initial Installation and Configuration28Use a USB flash drive: Requirement: A FAT32- or supperfloppy-formatted USB flash drivecontaining special configuration files is required. Procedure: Plug this USB drive into the PX3TS. When a happy smileyis shown on the front panel display, press and hold one of the controlbuttons on the front panel until the display turns blank.SeeConfiguration or Firmware Upgrade with a USB Drive (onpage 666).Cascading Multiple PX3TS Devices for Sharing Ethernet ConnectivityImportant: To upgrade an existing USB-cascading chain from anypre-3.3.10 firmware version to version 3.3.10 or later, follow theUpgrade Sequence in an Existing Cascading Chain (on page 415).You can have multiple PX3TS devices share one Ethernet connection bycascading them via one of the interfaces below: USB interface -- for cascading multiple PX3TS or multiple iX7 ™PDUs Ethernet interface -- for cascading multiple iX7 ™ PDUsThe first one in the cascading chain is the master device and all the otherare slave devices. Only the master device is physically connected to theLAN -- wired or wireless.Each device in the chain is accessible over the network, with the Bridgingor Port-Forwarding cascading mode activated on the master device. SeeSetting the Cascading Mode (on page 282). Bridging: Each device in the cascading chain is accessed with adifferent IP address. Port Forwarding: Each device in the cascading chain is accessedwith the same IP address(es) but with a different port numberassigned.Basic cascading restrictions: All devices in the chain must run "compatible" firmware versions. Firmware version 3.3.10 or later is NOT compatible withpre-3.3.10 firmware versions in terms of the cascading featureso all devices in the cascading chain must run version 3.3.10 orlater.
