A.1.3 Setting up Baytech Power Switches
The following information pertains to the RPC-3 and PRC-5 power switches.
The Baytech power switch is a network attached device. Essentially, it is a power strip with network
connectivity enabling power cycling of individual outlets. Only 1 Baytech switch is needed within the
cluster (unlike the RPS-10 model where a separate switch per cluster member is required).
Since there is no independent means whereby the cluster software can verify that you have plugged
each cluster member system into the appropriate plug on the back of the Baytech power switch, please
take care to ensure correct setup. Failure to do so will cause the cluster software to incorrectly conclude
a successful power cycle has occurred.
As shipped from the manufacturer, all of the outlets of a Baytech switch
are set to off. To power on the outlets into which the cluster members are
plugged, use the Baytech's configuration menus by starting from the main
menu, then selecting
individual outlets, for example
When setting up the Baytech switch the following configuration guidelines should be followed.
When configuring the Baytech power switch itself:
1. Using a serial connection, assign the IP address related parameters.
2. Under the

3. Assign a user name and password under the
account with an assigned password. Note: this password is stored in clear text in the cluster con-
figuration file, so choose a password which differs from the system's password (even though the
file permissions for the file /etc/cluster.conf are only readable by root).
4. To assign the system names to the corresponding outlets, go to the

assuming these are the cluster member names).
When running cluconfig to specify power switch parameters:
• Specify a switch type of BAYTECH.
• Specify the username and password assigned to the Baytech switch (refer to Step 3 in prior sec-
tion).
