v Universal ports that self-configure as E_Ports, F_Ports, EX_Ports, M_Ports (mirror ports), and FICON
ports. Note that the 10-Gbps ports on the FC32-48 port blade can function as E_Ports only.
v
ClearLink Diagnostic port (D_Port) functionality on Fibre Channel ports.
v Data compression capabilities through the port blades when ports are configured as ISLs.
Hardware components
The device has a modular and scalable mechanical construction that allows a wide range of flexibility in
installation, fabric design, and maintenance. The device can be mounted with the cables facing either the
front or the rear of the equipment rack, and consists of the following:
v Up to four slots for hot-swappable port blade assemblies, providing up to 256 32-Gbps Fibre Channel
ports if FC32-64 port blades are installed. FlexPort technology allows QSFP+ and QSFP28 ports on this
blade to be configured for FCoE operation at 4x10 GbE, 4x25 GbE, and 40 GbE speeds. For a list of
supported transceivers for these blades, refer to “Supported transceivers and cables” on page 65.
v Two half-size slots for control processor (CP) blades:
– A single active CP blade can control all the ports in the device.
– The standby CP blade assumes control of the device if the active CP blade fails.
v Two slots for core routing (CR) blades:
– CR blade interconnects all port blades.
– Up to 16 4x32-Gbps QSFP28 (ICL) ports.
– ICL ports allow interconnection with neighboring Director chassis
– Both CR blades are active and can be hot-swapped.
– For a list of supported transceivers for these blades, refer to “Supported transceivers and cables” on
page 65
v Up to four slots for modular, hot-swappable 34-port SX6 extension blades. Blades provide 16 32– Gbps
Fibre Channel (FC) ports supporting 8, 16, and 32 Gbps or 16 16-Gbps FC ports supporting 4, 8, and 16
Gbps; 16 GbE ports supporting 1 or 10 Gbps; and 2 GbE ports supporting 40 Gbps. Extension blades
enable long-distance communication over an existing IP infrastructure. For a list of supported
transceivers for these blades, refer to “Supported transceivers and cables” on page 65.
v Modular, hot-swappable field-replaceable units (FRUs):
– Two fan assemblies, available with nonport-side intake (NPI) or nonport-side exhaust (NPE)
airflow.
– Up to two power supply assemblies, available with nonport-side intake (NPI) or nonport-side
exhaust (NPE) airflow.
- Refer to the "Power supply specifications (per PSU)" in the Appendix B, “Product Specifications,”
on page 231 for maximum output power, input voltage, input line frequency, and other
specifications for your power supply model.
- Refer to the "Power supply requirements" section in the Appendix B, “Product Specifications,” on
page 231 for the minimum number of power supplies required for operation and redundancy
when different input voltages are used, such as low line and high line AC.
- Refer to "Power Consumption" sections in the Appendix B, “Product Specifications,” on page 231
for power output data and minimum number of power supplies for supported input voltages.
- Redundant primary power connections ensure high availability. Each power supply assembly has
its own connector, so the number of primary power connections is two for optimum efficiency
and redundancy.
– Two World Wide Name (WWN) cards located on the nonport side of the device behind the WWN
card bezel.
– Port blades use small form-factor pluggable (SFP+, QSFP+, and QSFP28) optical transceivers. For
details on supported transceivers per blade type, refer to “Supported transceivers and cables” on
page 65.
