Port Panel of a QFX5100-48S Device

28
The port panel of the QFX5100-48S switch supports up to a maximum of 72 logical 10
GbE ports when operating as a standalone switch. Forty-eight physical ports(
) support 10 Gbps small form-factor pluggable plus (SFP+) transceivers. These ports
47
can be configured as access ports. See
QSFP+ Transceivers for the QFX Series" on page 94
SFP+ DAC Cables for the QFX Series" on page
SFP+ transceivers or SFP+ direct attach copper (DAC) cables. You can use 1-Gigabit
Ethernet SFP+, 10-Gigabit Ethernet SFP+ transceivers and SFP+ DAC cables in any access
port.
The remaining 24 logical ports are the six 40 GbE physical ports (
support up to 6 quad small-form factor pluggable plus (QSFP+) transceivers . Each
QSFP+ socket can operate either as a single 40 Gbps port or as a set of 4 independent
10 Gbps ports using QSFP+ breakout cables. The 40 GbE ports can be configured as
either access ports or as uplinks. See
Cables for the QFX Series" on page
CAUTION: Do not place a copper transceiver in an access port directly above
or below another copper transceiver. Internal damage to the access ports
and switch can occur. We recommend either using the top port row
exclusively, or bottom port row exclusively, for copper transceivers.
To connect a QFX5100-48S switch as a node device in a QFabric system, you need:
Four QSFP+ uplink ports on each QFX5100-48S Node device to connect to the data
plane network through the QFX3008-I or QFX5100-24Q Interconnect devices.
The two remaining QSFP+ uplink ports on each QFX5100-48S Node device connect
to the data plane network through the QFX3008-I or QFX5100-24Q Interconnect
devices. See "Interface Specifications for SFP, SFP+, and QSFP+ Transceivers for the
QFX Series" on page 94.
To connect a QFX5100-48S switch as a member in a QFX Virtual Chassis, you need a
pair of dedicated ports and cables that link each member in the Virtual Chassis into a
ring topology. Each member in the ring has at least one direct Virtual Chassis port (VCP)
connection to a upstream and downstream member. QFX5100-48S switches are
recommended in the master, backup, or line card role. When mixed with QFX3500 or
QFX3600 devices, configure the QFX5100-48S in the master and backup roles. See
Connecting QFX Series Switches in a Virtual Chassis for cabling diagrams.
To connect a QFX5100-48S switch as a spine or leaf device in a Virtual Chassis Fabric
(VCF), you need a pair of dedicated ports and cables that link each spine device and leaf
device in the VCF. All spine devices have at least one direct VCP connection to each leaf
device in the VCF. See "Connecting a QFX5100 Device in a Virtual Chassis Fabric" on
page 187 for a cabling diagram.
