The Catalyst 2950G-24-EI-DC and Catalyst 2950ST-24 LRE 997 switches have
an internal DC-power converter. It has dual feeds (A and B) that are diode-OR-ed
into a single power block. For installation instructions, see
"Connecting to DC Power."
You must connect the Catalyst 2950G-24-EI-DC and 2950ST-24 LRE 997
switches only to a DC-input power source that has an input supply voltage from
–36 to –72 VDC. If the supply voltage is not in this range, the switch might not
operate properly or might be damaged.
Specific Cisco RPS models support specific Catalyst 2950 switches:
•
Cisco RPS 300 (model PWR300-AC-RPS-N1)
Cisco RPS 675 (model PWR675-AC-RPS-N1=)
•
The Cisco RPS 300 has two output levels: –48V and 12V with a total maximum
output power of 300W. Use the supplied RPS connector cable to connect the RPS
to the switch.
Attach only the Cisco RPS 300 (model PWR300-AC-RPS-N1) to the RPS
receptacle.
