Power Supplies
The AT-CV5000 chassis is shipped with two rear slots designated for the
power supplies. Two power supply options are available:
ˆ AT-PWR14 AC module
ˆ AT-PWR15 DC module
Caution
The AT-CV5000 Media Converter chassis can contain two power
supplies of the same type (AC or DC) or a combination of the two
versions with the same power ratings. Make sure not to mix power
supplies with different power ratings in the same chassis.
For information on the power supply module, refer to the
documentation that is shipped with the module.
An AC powered chassis is shown in Figure 8 and a DC-powered chassis is
shown in Figure 9.

Figure 9. AT-CV5000 DC Powered Chassis
When two power supplies are installed, one provides full power to the
chassis and the one of them works in standby mode. If one power supply
fails, the remaining power supply provides all the power to the system,
preventing a system failure.
