Statement 1017

Warning

This product relies on the building's installation for short-circuit (over current) protection. Ensure

that the protective devices is rated not greater than 20A (North America), 16A (Europe),and 13A

(UK).

Statement 1005

Caution

To ensure proper airflow it is necessary to rack the servers using rail kits. Physically placing the units

on top of one another or "stacking" without the use of the rail kits blocks the air vents on top of the

servers, which could result in overheating, higher fan speeds, and higher power consumption. We

recommend that you mount your servers on rail kits when you are installing them into the rack because

these rails provide the minimal spacing required between the servers. No additional spacing between

the servers is required when you mount the units using rail kits.

Caution

Avoid uninterruptible power supply (UPS) types that use ferroresonant technology. These UPS types

can become unstable with systems such as the Cisco UCS, which can have substantial current draw

fluctuations from fluctuating data traffic patterns.
