Monitoring the Server
Excluding / Including Clocks, SPS, XSP Cables and Sidebands
PAM software automatically manages and optimizes server ring connections. There are four
types of ring connections:
• Clocks
• SPS
• XSP cables
• Sidebands (dedicated to error and reset logs)
In the event of a failure, your Customer Service Engineer may request you to logically
exclude a clock, SPS, XSP cable and/or sideband until the failure has been repaired.
Excluding / Including Clocks
For high flexibility, availability and optimum performance, each CSS module is equipped
with two clocks (one on each Core unit MSX board). Only one clock is required per domain.
If a clock is faulty, you can logically exclude it to ensure correct server operation until
replaced. Once the fault has been repaired, you can logically include the excluded clock.
To logically exclude / include a clock:
1. From the PAM Tree pane, click Configuration Tasks → Ring Exclusion to open the Control
pane.
2. Select the Clock tab to display current server clock configuration.
