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.
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.
