QSFP+ DAC cables
QSFP+ to SFP+ direct attach copper breakout (DACBO) cables
Access ports—You can use 40-Gigabit Ethernet QSFP+ transceivers and QSFP+ DAC
cables in any downstream port. See
on page 130.
Uplink ports—You can configure all the QSFP28 ports as uplinks.
On the QFX10000-30C, the ports are enabled by default, and the default configuration
adds the ports to the default VLAN.

Status and Activity LEDs

All QSFP28 ports have an up or down indicator for each port and four bi-colored LEDs
that show port status and link activity based on whether or not the port is configured for
channelization. See Figure 37 on page 74

Description
The port is administratively disabled, there is no power, the link is down, or a
transceiver is not present. All sub-channels are disabled.
A link is established. When channelized, all sub-channels are up. When not
channelized, it indicates no activity.
A link is up and there is activity. When not channelized, it indicates the port is up
and active in either 40-Gigabit or 100-Gigabit mode. When channelized, all four
channels are up and active.
At least one channel link is up, but not all channels are up. There is no activity on
the channel link.
At least one channel link is up, but not all channels are up. There is activity on the
channel link.
The beacon function is enabled on one or more sub-channels.
One or more sub-channels has a fault condition.
