There are two types of management boards:
RJ-45 management board—Provides two 1000BASE-T RJ-45 management ports.
If you are using the QFX3500 device as a Node device in a QFabric system, see
Specifications for Copper-Based Control Plane Connections for the QFabric System"
on page 265 for information about the required cables.
If you are using the QFX3500 device as a standalone switch, see
for Console and Management Connections for the QFX Series" on page 268
information about the required cables.
SFP management board—Provides two 1-Gbps small form-factor pluggable (SFP)
management ports. See Determining Interface Support for the QFX3500 Device for
information about the supported transceivers and required cables.
In addition to the fan trays, two fan modules on the management board provide airflow
to cool the chassis. The management board provides FRU-side-to-port-side or
port-side-to-FRU-side airflow depending on the device model you purchase.
Table 26 on page 129 lists the different management boards and their direction of airflow.
The management boards are designed so that they can only be inserted into the QFX3500
model that supports the same airflow type.
NOTE: The front panel of the device where the power supplies, fan trays, and
management boards are located is the FRU side of the device.
