ports causes the ports to go down, log a system log error, and remain down.
You must manually remove the channelization configuration on the ports to
bring the ports up in default mode.
Use the
request chassis system-mode
command to change the system mode for the
switch. If you attempt to channelize a non-supported port, the configuration is ignored.
Virtual Chassis and Virtual Chassis Fabric
To connect QFX5110 switches as members in a QFX5110 Virtual Chassis, you need a pair
of dedicated ports on each switch 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. QFX5110 switches are
recommended in the master, backup, or line card role. You may only mix QFX5100
members with QFX5110 members in a QFX5110 Virtual Chassis; no other QFX Series or
EX Series switches are supported. See
“Connecting QFX5110 and QFX5100 Members in
a QFX5110 Virtual Chassis” on page 95 for a a diagram of cabling QFX5110 switches in a
ring topology.
To connect a QFX5110 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 QFX5110 Device in a QFX5110 Virtual Chassis Fabric” on
page 96 for a cabling diagram.

QFX5110 Field-Replaceable Units
Field-replaceable units (FRUs) are components that you can replace at your site. The
QFX5110 FRUs are hot-insertable and hot-removable: you can remove and replace one
of them without powering off the switch or disrupting the switching function.
CAUTION: Replace a failed power supply with a blank panel or new power
supply within one minute of removal to prevent chassis overheating. The
switch continues to operate with only one power supply running. Replace a
failed fan module with a new fan module within one minute of removal to
prevent chassis overheating. Do not operate the switch with missing FRUs
for longer than one minute.
Table 6 on page 16 lists the FRUs for the QFX5110 and actions to take before removing
them.
