Redundant Twisted Pair Ports

Four of the twisted pair ports on the x600-24-Ts and x600-24-Ts/XP switches are paired with SFP slots. The twisted pair ports are identified with the letter “R” for “Redundant” as part of their number on the faceplate of the unit. The ports and slots are listed in Table 2.

Table 2. Twisted Pair Ports Matched with SFP Slots

Models	Ports and Slots
x600-24Ts and	21R with SFP slot 21
x600-24Ts/XP	22R with SFP slot 22
	23R with SFP slot 23
	24R with SFP slot 24

Follow these guidelines when using these ports and slots:

ˆOnly one port in a pair can be active at a time. It can be either the twisted pair port or the corresponding SFP module.

ˆThe twisted pair port is the active port when its SFP slot is empty, or when an SFP module is installed but has not established a link to an end node.

ˆThe twisted pair port automatically changes to the redundant status mode when an SFP module establishes a link with an end node.

ˆA twisted pair port automatically transitions back to the active status when the link is lost on the SFP module.

ˆIn nearly all cases, a twisted pair port and an SFP module share the same configuration settings, including port settings, VLAN assignments, access control lists, and Spanning Tree Protocol settings.

ˆAn exception to the shared settings is port speed. If you disable Auto- Negotiation on a twisted pair port and set the speed and duplex mode manually, the speed reverts to Auto-Negotiation when an SFP module establishes a link with an end node.
