Webcache — Rear View Detail 21

console port uses a standard null-modem cable and is set to 9600 baud, 8 data bits, no parity and 1 stop bit.

WAN Port The WAN port is an auto-negotiating 10BASE-T/100BASE-TX RJ-45 port. It is used to connect the Webcache to the network in an inline deployment environment.

CAUTION: The Webcache does not support inline deployment in Version 1.0. You should not connect network cabling to the WAN port.

LAN Port The LAN port is an auto-negotiating 10BASE-T/100BASE-TX RJ-45 port. It is used to connect the Webcache to the network in either Proxy or Transparent deployment environments. Web network traffic travels to and from the Webcache via the LAN port. For more information, see “Deploying the Webcache in Your Network” on page 33.

You must connect the LAN port to your network using an appropriate network cable. For more information, see the “Cable Specifications and Pin-outs” appendix on page 147.
