  • Page 20 Common data center protocols: Like the EX9000 series, the EX4650 also uses data center network protocols. The network protocols used in the EX4650 are the Ethernet VPN (EVPN) and the Virtual Extensible LAN (VXLAN). Engineers typically use it with the Border Gateway Protocol and the VXLAN encapsulation protocol which creates an overlay network on an existing Layer 3 infrastructure.
  • Page 21 Ethernet transceiver is connected, you can only set the speed to 25G. For the SFP+ ports, you can set the speed to 25G or 1G. There is no commit check for this, however. On EX4650 switches, the uplink ports support auto-channelization. Table 4 on page 12 summarizes the supported port speeds on EX4650-48Y.
  • Page 22 EX4650-48Y does not support autonegotiation when 1-gigabit fiber SFP transceiver is plugged in. In such cases, it is recommended to disable auto-negotiation on the remote end device. But, EX4650-48Y switches with 1-gigabit copper SFP transceiver supports autonegotiation, as the physical layer within the transceiver handles autonegotiation.
  • Page 23 Channelization in EX4650 Switches EX4650 Switch First View The EX4650 switch has a 1 U form factor and is shipped with redundant fans (4+1) and redundant power supplies (1+1).

  • Page 196: Prevention Of Electrostatic Discharge Damage

    Prevention of Electrostatic Discharge Damage Device components that are shipped in antistatic bags are sensitive to damage from static electricity. Some components can be impaired by voltages as low as 30 V. You can easily generate potentially damaging static voltages whenever you handle plastic or foam packing material or if you move components across plastic or carpets.
