Physical

CPU/Memory

• 64-bit MIPS Processor, 1 GHz clock, single core

• 1GB ECC DDR3 DRAM

• 4GB eMMC Flash

• 1.5MB packet buffer on 12 - 24 port switches, 3.0MB packet

buffer on 48-port switches

LED Indicators

• Per port status LED including power status

• System Status LEDs: management, fan and power

• 7 segment display of stack number – operational on switches

that support stacking

Stacking

• SummitStack-V with support for up to eight switches per

stack

• Mixed stacking with other ExtremeXOS Series switches, so

long as all are running the same ExtremeXOS version

• Requires two of the four available X440-G2 uplink ports

Note: SummitStack-V stacking is enabled on two of the four

X440-G2 uplink ports by default (no license required). All stacking

ports operate at 10Gb but do not use standard Ethernet protocols.

X440-G2 uplink ports, when not used for stacking, run the

standard Ethernet protocol. Non-stacking uplink ports are limited

by default to 1GbE, unless upgraded via software license. 10GbE

licenses are available, in both two- and four-port versions, as well

as a license to upgrade a dual 10GbE uplink switch to a four 10GbE

uplink switch, that enable X440-G2 uplink ports to run the 10Gb

Ethernet protocol.

 

Mapping of the two default X440-G2 stacking ports to their respective physical chassis interface #’s — by chassis type — are listed

below.
