Ports 23R and 24R on the AT-9424T/GB, AT-9424T/SP, and
AT-9424Ti/SP Series Switches
This section applies to the twisted pair ports 23R and 24R and the SFP
and GBIC slots on the AT-9424T/GB, AT-9424T/SP, and AT-9424Ti/SP
Series switches. Note the following when configuring these ports:
ˆ Twisted pair ports 23R and 24R change to the redundant status mode
when an SFP or GBIC module is installed and establishes a link with
its end node. An SFP or GBIC port is only active while it has a valid
link. At all other times the corresponding twisted pair port 23R or 24R
is the active port.
ˆ A twisted pair port and its corresponding SFP or GBIC module share
the same configuration settings, including port settings, VLAN
assignments, access control lists, and spanning tree. When an SFP or
GBIC module becomes active, it operates with the same settings as its
corresponding twisted pair port.
ˆ An exception is port speed: If you disable Auto-Negotiation on the
twisted pair port and set the speed and duplex mode manually, the
speed reverts to Auto-Negotiation when you install an SFP or GBIC
module and the module establishes a link with an end node.
ˆ To specify twisted pair port 23R or 24R in a menu’s prompt, enter “23”
or “24”.
