Cooling
Cooling within the SL3000 library is divided into three areas:
Electronics control module
■
Tape drives
■
DC power supplies
■

Library Electronics Control Module

Two fans, located to the right of the electronics control module, provide cooling for the
electronics in the library. Air is drawn from the sides of the library and flows through
the fans to the rear of the library.
The library controller card (HBCR) monitors these fans for proper operation.
■
An amber Fault indicator is on the fan assembly to indicate a failure.
■
While there are two dedicated fans, one fan is sufficient to provide adequate cooling
for the library and the electronics. The fans can be replaced without interfering with
library operations. Therefore, replace a defective fan when it is detected.
