HP A7340-96002 manual Power Supply Side

The ports on the SFP media side of the FC 16B are color-coded in groups with four purple ports alternating with four unmarked ports to indicate which ports can be used in the same ISL Trunking group.

Note ISL Trunking (an optionally licensed feature) is a Fabric OS feature that enables distribution of traffic over the combined bandwidth of up to four ISLs between two directly adjacent switches, while preserving in-order delivery. For information about ISL Trunking, refer to the ISL Trunking User’s Guide.

Power Supply Side

Figure 11 shows the power supply side of the FC 16B, which provides access to the fan trays and power supplies and the Switch Status LED. Each power supply also has an LED that indicates the status of that power supply. The power supplies, fan trays, and entire switch are all FRUs (field replaceable units).

Power Supply

The power supplies are universal and capable of functioning worldwide without using voltage jumpers or switches. They meet IEC 61000-4-5 surge voltage requirements and are autoranging in terms of accommodating input voltages and line frequencies. Each power supply has its own built-in fan for cooling, pushing the air towards the SFP media side of the switch. See “Power Supply” on page 37 for a list of power supply specifications.
