Auto-Negotiation (AUTO) Switch
The auto-negotiation switch is applicable only to the fiber ports and is
enabled independently on each port. When AUTO is enabled, the fiber
port advertises full duplex capability and the mode of operation is
determined through the auto-negotiation process.
By default, AUTO is enabled (UP position). When AUTO is disabled,
the duplex mode is fixed at full duplex. Use AUTO1 to set auto-
negotiation on Port 1 and AUTO2 for Port 2.
For the copper port on the R153-1S, auto-negotiation is always enabled
and it cannot be changed.
Install the SFP Optics
The R153-1S and R153-SS require one or two sets of small form-factor
pluggable (SFP) optics. Each set of optics is shipped separately.
To install the optics, slide the SFP module into an empty slot, pushing
it firmly in place. Remove the protective covering on the LC
connectors.
