Maintaining the CSACS-1121, Cisco SNS-3400 Series, and Cisco SNS-3500 series Appliances Maintaining the CSACS-1121 Series Appliance Temperature Temperature extremes can cause a variety of problems, including premature aging and failure of integrated circuits (ICs) or mechanical failure of devices. Extreme temperature fluctuations can cause ICs to become loose in their sockets, causing expansion and contraction of disk drive platters, resulting in read or write data errors. -
Page 4: Altitude
Maintaining the CSACS-1121, Cisco SNS-3400 Series, and Cisco SNS-3500 series Appliances Maintaining the CSACS-1121 Series Appliance Altitude Operating an appliance at high altitudes (low atmospheric pressure) reduces the efficiency of forced and convection cooling which can result in electrical problems related to arcing and corona effects. This condition can also cause sealed components with internal pressure, such as electrolytic capacitors, to fail or perform at reduced efficiency. -
