when Auto Negotiation is not desired by configuring using DIP Switches #8
and #9.
3.5 Auto Negotiation
The HDMCII VDSL2 LAN Extender Module (Extended Temp) ships from the
factory with Auto Negotiation enabled on the DATA port. In this mode, the
DATA port negotiates for speed and duplex (i.e., the module detects 10
Mbps Full-Duplex, 10 Mbps Half-Duplex, 100 Mbps Full-Duplex or 100 Mbps
Half-Duplex with Flow Control). Configure Auto Negotiation on an HDMCII
VDSL2 LAN Extender Module (Extended Temp) by adjusting the DIP Switch
#5 (for unmanaged modules) or via the management software (for managed
modules).
3.6 Selective Advertising
Selective Advertising (DIP Switch #7), when used in combination with Auto
Negotiation, advertises only the configured speed and duplex mode for the
DATA port. If Selective Advertising and Auto Negotiation are both switched
ON, the DATA port’s speed (10 or 100 Mbps) and Duplex mode (FDX or
HDX) are selectively advertised individually per switch setting #5 and #7.
NOTE
If you require a specific speed and/or duplex mode, Black Box recommends using
Selective Advertising rather than Force Mode when connecting the modules to devices
that can ONLY Auto Negotiate. Selective Advertising is NOT an option when you
disable Auto Negotiation.
3.7 SNMP Management
Once the DIP Switches have been set on each module to enable one to be a
Host and the other a Remote, the Host can be installed in a High-Density
Media Converter System II chassis that includes an installed SNMP
Management Module. The Host VDSL2 module then manages the Remote
VDSL2 module via the SNMP software iView
