Power Specifications
Note
When you use a redundant power supply (RPS), only redundant power – not additive power –
is supported. Thus, the PoE ports load does not increase when an RPS is added.
Table 267: V300 Power Options
V300-8P-2X DC Input: 54VDC, 4.5A max
V300-8T-2X DC Input: 12VDC, 1.5A max
V300-8P-2T-W The PoE PSE Budget is dynamically determined by the 802.3bt
Type 4 PD input power applied to its uplinks as follows:
• 2 x 90W = PoE ports load to 105W
• 1 x 90W = PoE ports load to 50W
• 2 x 60W = PoE ports load to 75W
• 1 x 60W = PoE ports load to 30W
• 2 x 30W = PoE ports load to 30W
• 1 x 30W = PoE ports load to 0W
