Junos Juniper EX4550-32T-AFI 32-port never works witn 10Gb

Hi guys,

I tried to connect my server with EX4550 with 10Gb port but it never connects 10Gb but only 1Gb

when I set 10Gb manuall like below

xe-0/0/9 {

ether-options {

speed {

10g;

}

}

unit 0 {

family ethernet-switching;

}

}

​

it just does not work. when I checked link from server, it says "Link detected: no"

I tested my server can connect 10Gb. and here is the ethtool result when connected 1Gb with switch
