• One 10/100/1000BASE-T Ethernet management port.
Additional ports on various models include the following:
Table 26: X620 Series Switches and Port Types
100Mb/1 Gb/10GBASE-T 100Mb/1 Gb/2.5Gb/5Gb/
10GBASE-T
100Mb/1 Gb/10GBASE-X
with SFP+
X620-8t-2x 8 2
X620-10x 10
X620-16t 16 4 (see note)
X620-16x 16
Note: The 100Mb/1 Gb/10GBASE-X ports on the X620-16t and X620-16p are combination ports, shared
with the last four 10GBASE-T ports (LRM support; no 100Mb support)
For all models, a serial console port on the front panel allows you to connect a terminal and perform
local management. An Ethernet management port can be used to connect the system to a parallel
management network for administration. Alternatively, you can use an Ethernet cable to connect this
port directly to a laptop to view and locally manage the switch configurations.
The rear panel provides an AC power input socket. The X620-8t-2x and X620-10x switches support
external redundant power options, and the 16-port switches have modular internal redundant power
options.
The switch automatically adjusts to the supply voltage. The switches with redundant power connectors
can connect to the RPS-150XT or EPS-C2 external power system. When a compatible external power
supply is used with the X620 switch, the internal and external power supplies are fully fault tolerant. If
one power supply fails, the other power supply will provide sucient power to operate the switch.
The 16-port switches oer front-to-back or back-to-front airflow options. The X620-8t-2x and X620-10x
switches have side-to-side airflow with right-side exhaust.
Note
See the ExtremeXOS 30.7 User Guide and the ExtremeXOS 30.7 Command Reference Guide
for feature-specific information about the switches and for information regarding switch
configuration.
