Installing an Additional Cache Storage Device 77
Connecting the
Webcache
Use the following sequence of steps to connect the Webcache to your
network:
1 Connect an appropriate network cable to the LAN port on the rear panel
of the Webcache. Simply slot the connector on the cable into the RJ-45
LAN port. When the connector is fully in, its latch locks in place. To
disconnect the cable, push the connector’s latch in and remove it.
2 Connect the other end of the network cable to a 10BASE-T/100BASE-TX
port on a suitable switch or hub in your network. The switch or hub that
you connect the Webcache to is determined by the deployment
environment that you choose; for further information, see
“Deploying
the Webcache in Your Network” on page 70 .
Installing an
Additional Cache
Storage Device
The Webcache 3000 has two cache storage devices installed when you
purchase it. You can install an additional cache storage device in the third
bay of the Webcache 3000. This improves the performance of the
Webcache in the following ways:
■
Reduced Web Latency
The amount of time that the Webcache takes to respond to client
machine Web requests is reduced.
■
Increased Peak Throughput
The maximum amount of Web throughput that the Webcache can
serve is increased.
■
Increased Hit Rate
Additional Web content can be stored on the Webcache, increasing
the chances of a cache hit.
You need to purchase a hard drive approved by 3Com and insert it into
the mounting tray in the third bay of the Webcache. A list of approved
hard drives can be found at:
htpp://www.3com.com/sswebcache
CAUTION: You must purchase and install a hard drive that 3Com has
approved. Your warranty will be invalidated if you install an unapproved
drive.
For further information, see the “Installing an Additional Cache Storage
Device” appendix on page 317 .
