Acquire cables and connectors:
•
Determine the number of cables
needed based on your planned
configuration.
•
Review the maximum distance
allowed for each cable. Choose the
length of cable based on the
distance between the hardware
components being connected.
Plan the cable routing and
management.

Determining Transceiver Support for the QFX5110
The port panel of the QFX5110-48S supports 48 logical 10-Gigabit Ethernet ports. These
data ports (0 through 47) support either 1-Gigabit small form-factor pluggable (SFP) or
10-Gigabit Ethernet Ethernet small form-factor pluggable plus (SFP+) transceivers. You
can also use SFP+ DAC cables and 10-Gigabit active optical cables (AOC) in any access
port.
