Caution
The device transceiver type (single-ended or differential)
must match the bus segment type. Devices that do not meet
this condition cannot operate.
The allowed length of a bus segment depends on the electrical
loading, transmission media type, and data transfer rate. In many
cases, heavier loading, smaller wires, and higher speeds demand
shorter lengths. Increasing the number of devices on a given length of
the bus, by using longer stubs or higher capacitance devices, produces
loading.
cabinet
See data center cabinet and departmental server cabinet.
cache module

Callout n

CE–Mark
A European Economic Community (EEC) certification label that
identifies electronic devices authorized for sale within member
nations.

commercial environment. A CE–Mark certified device can also be
used in the United States.
CE–Mark Class B
Similar to, but more stringent than the FCC Class B certification, this
certification label appears on electronic devices that are for use in
either a home or a commercial environment. A CE–Mark certified
