Setting the Mode on an SFP+ Uplink Module (CLI Procedure)
SFP+ uplink modules are supported on EX3200 and EX4200 switches. You can use these uplink modules either for two SFP+ transceivers or four SFP transceivers. You configure the operating mode on the module to match the type of transceiver you want to
By default, the SFP+ uplink module operates in the
To set the operating mode of an SFP+ uplink module:
1.Change the operating mode to the appropriate mode for the transceiver type you want to use by using one of the following commands:
[edit]
user@switch# set chassis fpc 0 pic 1 sfpplus
[edit]
user@switch# set chassis fpc 0 pic 1 sfpplus
2.If the switch is running:
■JUNOS Release 10.1 or later, the changed operating mode takes effect immediately unless a port on the SFP+ uplink module is a Virtual Chassis port (VCP). If any port on the SFP+ uplink module is a VCP, the changed operating mode does not take effect until the next reboot of the switch.
NOTE: During the operating mode change, the Packet Forwarding Engine is restarted. In a Virtual Chassis configuration, this means that the Flexible PIC Concentrator connection with the master is dropped and then reconnected.
■JUNOS Release 10.0 or earlier, reboot the switch.
You can see whether the operating mode has been changed to the new mode you configured by issuing the show chassis pic
