Auto-Negotiation (AN1)
AN1 is the auto-negotiation switch for Port 1. When auto-negotiation is
enabled, the port advertises 10/100 Mbps and half/full duplex capability
to its link partner. When auto-negotiation is disabled, the speed and
duplex for Port 1 are set through the SPD1 and DUP1 switches.
Note:
Speed and duplex are dependent upon auto-negotiation. If AN1 is
enabled, the SPD1 and DUP1 switches will be ignored.
Speed (SPD1)
The speed switch applies to Port 1 and is effective only when auto-
negotiation (AN1) is disabled. Port 1 is set to 100 Mbps when SPD1 is
up, and 10 Mbps when SPD1 is down.
Duplex (DUP1)
The duplex switch applies to Port 1 and is effective only when auto-
negotiation (AN1) is disabled. Port 1 is set to full duplex when DUP1 is
up, and half duplex when DUP1 is down.
3. Install the SFP Optics
The R821-1S requires one small form-factor pluggable (SFP) optic.
Optics are shipped separately.
