    Hello,

    Can any one help me with my inquiry.

    Does EX 4650 come with empty ports ?

    if yes can i use 24  port with 1G SFP copper

    and other  24 port  with 10 G SFP + fiber

    How many power supply has this swith been shipped with ?

    Thanks in advance ..

    Hey HDawood

     

    Greetings, the EX4650 switch models are shipped with two power supplies preinstalled in the rear panel of the chassis.

     

     

    can i use 24  port with 1G SFP copper

    and other  24 port  with 10 G SFP + fiber

     

     

    Yes, it has forty-eight 25-Gigabit Ethernet ports that can operate at 1-Gbps, 10-Gbps, or 25-Gbps speed and support SFP, SFP+, or SFP28 transceivers, it all depends on the transceivers. 

     

    Here you can find lists the components shipped with EX4650 switch models and more:

    EX4650 Switch Models

    The EX4650 switch is available with 48 ports and supports AC and DC power supplies depending on the switch model. All models of the EX4650 ship with two power supplies and five fans installed by default. Table 2 lists the components shipped with EX4650 switch models.

    Hi HDawood,

     

    May i ask you to clarify what do you mean by empty ports ? according to the datasheet EX4650 offers 48 wire-speed 10GbE/25GbE small form-factor pluggable and pluggable plus transceiver (SFP/SFP+/SFP28) ports and 8 wire-speed 40GbE/100GbE quad SFP+ transceiver (QSFP+/QSP28) ports. Switch can support mixed 1GbE, 10GbE, 25GbE, 40GbE, and 100GbE environments.

     

    Regaerding power supplies four models are available: two featuring AC power supplies with front-to-back or back-to-front airflow, and two featuring DC power supplies with front-to-back or back-to-front airflow. All models include dual power supplies.

    EX4650-18Y, like EX4600 is a fiber based switch.  The 'Y' indicated 10/25 GE support.  The EX4650 has 48 x 1/10/25 (SFP/SFP+/SFP28) GE ports and 8 40/100GE ports (QSFP+/QSFP28).

     

    The EX4650 can support all 48 ports, with any form of optic, even 10GE-Base-T.  The newer 10GE-Base-T optics from Juniper are smaller in width, so there are no longer any physical mechanical issues with using all 48 ports with these optics.  The old restriction of max 24 of these 10GEBase-T optics is no longer true, and has not been true for quite some time.

     

    You could find all this info by searching for EX4650-48Y datesheet.  Link is below:

    Hi HDawood, 

     

    Greetings, 

     

    1. Does EX 4650 come with empty ports ?
    Yes, it does come up with 56 empty ports (like below) 

     

     

    2. If yes, can i use 24  port with 1G SFP copper and other  24 port  with 10 G SFP + fiber.

    Yes again, so the datasheets points out it has 48 x 10/25GbE and 8 x 40/100 options. You can use 24 ports with 1G copper SFP and 24 others with 16G SFP+.

     

    3. How many power supply has this swith been shipped with ?

    Two Power Supplies, there are 4 different models and all of them include dual power supplies.

     

    Hope this helps. Smiley Happy

    Hi HDawood,

     

    Yes, like most switches, EX4650 is shipped with empty ports.  Featuring 48 wire-speed 10GbE/25GbE small form-factor pluggable and pluggable plus transceiver (SFP/SFP+/SFP28) ports and 8 wire-speed 40GbE/100GbE quad SFP+ transceiver (QSFP+/QSP28) ports in a compact 1 U platform, the EX4650 provides the flexibility to support mixed 1GbE, 10GbE, 25GbE, 40GbE, and 100GbE environments. It depends on what transceiver you plugin on the port.

     

    Four models are available: two featuring AC power supplies, and two featuring DC power supplies. All models include dual power supplies. These are Dual redundant (1+1) and hot-pluggable 650 W AC/DC power supplies.

     

    Hope this helps 🙂
