WARNING: Never operate the C-Series System without a fan tray.
WARNING: The C7008/C300 operates in either of two voltage ranges. Each range supports a different supply
configuration. As a safety precaution, do not install more than the recommended maximum number of PSUs
(given by the table below), as this causes high leakage current. Install blank panels in all unused PSU slots.
To supply the C-Series System:
To turn off the AC supplies:
• Toggle the switch two the OFF position.
• Unplug the cord from the receptacle on the front of the supply.
• Verify that the LEDs are unlit.
After you supply to the system, the following should occur:
• The fan tray should be operating.
• The green (online) fan tray, RPM, and line card LEDs should be lit and remain lit as long as the system
is receiving and is operational.
When you supply to the C7008/C300, the system performs a series of -on self tests. RPM and line card
LEDs blink as the diagnostic programs run. No user interaction is required at this point. Observe the
process on your console monitor. When the boot process is complete, the card LEDs remain online
(green) and the console monitor displays the Command Line Interface (CLI) prompt.
Voltage Frequency Maximum PSU
100 -120 50/60Hz 7 p 1 redundant
200 - 240 50/60Hz 7 p 1 redundant
