Recovering from a Blank Screen
Occasionally, while you are performing a RAID
management operation using WebPAM PRO, your
browser screen might go blank.
To recover from a blank browser screen, do one of the
following actions:
• Press the F5 key.
• Click your browser’s Refresh button (right).
Cache Battery Does Not Charge
The RAID controller’s cache backup battery protects data in the cache for up to
72 hours in the event of a power failure. If the battery is too warm, it will not
accept a charge nor will it discharge to power the cache.
To view battery information:
1. Click the Subsystem icon in Tree View.
2. Click the Controllers icon.
3. Click the Controller icon.
4. Click the Battery tab in Management View.
In normal operation, the operational status of the battery shows Fully Charged
with a Reserve Capacity of 100%. If it never reaches this condition or remains
discharged, the battery may be too warm.
RAID controllers, like all components inside the Host PC, rely on a flow of air to
carry off heat and maintain optimal temperature. If the air flow is inadequate,
performance can suffer.
Check and correct the following conditions:
• Ambient operating temperature must not exceed 104
°F (40°C).
• Be sure the fan outlets, typically at the back of the PC or server, have at
least 6 inches (15 cm) of clearance.
• If you have other PCI devices and available slots, try moving the SuperTrak
and the other devices further apart to increase airflow between them.
• Airflow through your PC or server must be at least 200 LFM.
Measuring and adjusting airflow through a PC or server is very difficult for users
in the field. Contact the manufacturer’s Technical Support for assistance.
