XRE200 Network Cable and Transceiver Planning

 

Pluggable Transceivers Supported on XRE200 External Routing Engines

The SFP Virtual Chassis Control Interface (VCCI) module for XRE200 External Routing Engines supports SFP transceivers. You can find the list of transceivers supported on XRE200 External Routing Engines and information about those transceivers at the Hardware Compatibility Tool page for XRE200.

Note

We recommend that you use only optical transceivers and optical connectors purchased from Juniper Networks with your Juniper Networks device.

Caution

If you face a problem running a Juniper Networks device that uses a third-party optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem. Your JTAC engineer might recommend that you check the third-party optic or cable and potentially replace it with an equivalent Juniper Networks optic or cable that is qualified for the device.

The Gigabit Ethernet SFP transceivers installed in XRE200 External Routing Engines support digital optical monitoring (DOM): You can view the diagnostic details for these transceivers by issuing the operational mode CLI command show interfaces diagnostics optics.

Cables Connecting the XRE200 External Routing Engine to XRE200 External Routing Engines and EX8200 Switches

An XRE200 External Routing Engine connects to EX8200 switches and XRE200 External Routing Engines to form a Virtual Chassis topology. An XRE200 External Routing Engine connects to the management Ethernet port (labeled MGMT) on the Routing Engine when connecting to EX8200 switches. XRE200 External Routing Engines connect to any Virtual Chassis port (VCP) when connecting to other external Routing Engines.

The same cables are used to connect XRE200 External Routing Engines to EX8200 switches or to XRE200 External Routing Engines. Table 1 lists the specifications for the cables that connect the XRE200 External Routing Engine to EX8200 switches. Table 2 lists the specifications for the cables that connect XRE200 External Routing Engines to one another.
