Enhanced Predictive Failure Analysis
The Cisco MCS 7835-I2 supports Enhanced Predictive Failure Analysis (PFA) on hot-swap fans,
power supplies, processors, and memory and voltage regulator modules. Through diagnostics, the
Cisco MCS 7835-I2 anticipates failures in these devices and generates an alert, allowing service
personnel to quickly replace the components before a failure actually occurs. An example of PFA
is its ability to monitor variations in electrical input/output to the power supplies and cooling fans.
DAT Support
The Cisco MCS 7835-I2 appliance can support an optional 36-/72-GB USB external Digital Audio
Tape (DAT) drive (part number DAT-USB-EXT-72=) or an optional USB rack-mount DAT drive
(part number DAT-USB-RM-72=). This tape drive connects through one of the 4 USB 2.0 ports
provided by the Cisco MCS 7835-I2 appliance.
