Ciena offers the following AC power cables for the 5150:
• AC Power Cord, IEC C13, Europe
• AC Power Cord, IEC C13, North America
• AC Power Cord, IEC C13, United Kingdom
• AC Power Cord, C13, Universal
Connecting DC power to the 5150 power supplies
In order to successfully replace the power supply while the unit is operating,
the DC power supplies must be powered off separate breakers. This allows
you to turn off power feeding the power supply that is being replaced. While
the second independent circuit remains on, and powers the unit during the
replacement process. As a result, Ciena recommends that each DC power
supply be connected to a separate breaker.
For installations using 24 V or 36 V input voltage, the recommended fuse
value is a minimum of 15 Amps. For systems using 48 V input voltage, the
recommended fuse value is a minimum of 7.5 Amps and a maximum of 15
Amps.
The DC power cord should be 14 AWG wire. You will need to install fork
terminal spade lugs on the power cord to ensure a proper connection with the
terminal block of the power supply. Table 2-2 on page 2-9 contains a summary
of the recommended locking fork terminal lugs. In addition it should be noted
that after it is installed, the power cord will be dressed to the right, across the
front of the power supply. It is not appropriate to dress the power cord to the
left, across the front of the 5150 chassis. See “To Install a DC Power Supply”
on page 2-22 for a procedure.
WARNING: A readily accessible disconnect device shall be incorporated
external to the equipment.
