Partitioning or Channelizing Switch Ports into Data Lanes
Six of the eight 100GbE front-panel ports operate in either 100-gigabit or 40-gigabit mode. Two of the
ports can each be partitioned into data lanes through the use of breakout cables. This means that a
given physical port can correspond to either two or four logical ports.
Logical port numbers are assigned depending on whether the physical ports are partitioned into data
lanes. If there is no partitioning or channelizing, the logical port numbers correspond to the physical
port numbers shown on the front of the switch. With partitioning or channelizing, logical port numbers
are assigned for each of the physical ports – as shown, for example, in the following table:

Stacking
Each X695 unit comes equipped with two 40GbE or 100GbE stacking ports using a QSFP28 interface,
located on the front panel of the switch. Use standard 100 Gb Ethernet Optics and passive and active
cables in the QSFP28 ports for stacking X695s together using SummitStack-V400.
Stacking cables for X695 switches are ordered separately. For a list of X695 ports that can be used with
SummitStack-V160 and SummitStack-V400, see
ExtremeSwitching X695 Stacking
on page 205.
For information about QSFP and QSFP+ optical modules, see
Extreme Networks Pluggable Transceivers
Operating Temperatures
All X695 switch models support an operating range from 0°C to 50°C for front-to-back cooling, 0°C to
45°C for back-to-front cooling.
Note
See the
and the
ExtremeXOS 30.7 Command Reference Guide
for feature-specific information about the switches and for information regarding switch
configuration.
