VSP 4450 Series Notes on Combination Ports

When the VSP 4450 Series is reset, the peer connections for all ports, including combination ports 47 and 48 on VSP 4450GTX-HT-PWR+, will transition down. During the reset, the fiber ports remain down, but only the copper ports 47 and 48 come up periodically throughout the reset. The copper ports 47 and 48 come up approximately 15 seconds into the reset, remain up for approximately 60 seconds, and then transition down until the boot sequence is complete and all ports come back up.

The following is an example of the status of the combination ports during reset.

Cabled Connections for Both Copper and Fiber Ports

The following limitations apply when the combination ports have cabled connections for both the copper and fiber ports.

Do not use the fiber port and do not insert an SFP into the optical module slot in the following situations:

Note

Note

These limitations apply only when auto-negotiation is disabled. To avoid this limitation, use auto-negotiation to determine the speed to 10/100/1000 and to determine the duplex.

The 100M-FX SFP requires auto-negotiation to be disabled. Therefore, auto-negotiation will also be disabled for the copper port. Configure the peer switch to disable auto-negotiation.
