W&T Network interface
Subject to error and alteration
transmission parameters with respect to speed and duplex.
To prevent communications problems (duplex mismatch),
only the following two combinations are permissible:
• Both parties (switch and Com-Server) are operated in Auto-
Negotiation mode.
• Both parties are configured for the same (fixed) transmissi-
on speeds and duplex mode.
Use menu sequence Setup System r Link Speed to switch
between Auto-Negotiation and fixed transmission speeds/
duplex mode.
Power-over-Ethernet - PoE
The Com-Server++ can obtain power as defined in
IEEE802.3af/Power-over-Ethernet. Either the data pairs or the
unused wire pairs in 10/100BaseT may be used (see also the
section Supply Voltage).
