Twisted pair ports

Cable
requirements for
non-PoE ports
The number of twisted pair ports supported by each GS970M Series
switch is:
8 ports: GS970M/10 and GS970M/10PS

16 ports: GS970M/18 and GS970M/18PS

24 ports: GS970M/28 and GS970M/28PS

All ports are 10BASE-T, 100BASE-TX, and 1000BASE-T compliant. You
can set the port speeds and duplex modes either automatically with IEEE
802.3u Auto-Negotiation or manually with the management software.
The twisted pair ports feature 8-pin RJ45 connectors. For the port pinouts,
see "Connectors and port pinouts" on page 88.
The ports have a maximum operating distance of 100 m (328 feet).
The ports feature auto-MDI, which automatically configures the ports as
MDI or MDIX. This feature allows you to use straight-through twisted pair
cables regardless of the wiring configurations of the ports on the end
nodes.
Note
A switch port connected to an end node that is not using Auto-
Negotiation should not use Auto-Negotiation to set the speed and
duplex mode, as a duplex mode mismatch may occur. In this case,
disable Auto-Negotiation and set the port's speed and duplex mode
manually.
Cable requirements for the non-PoE twisted pair ports are in Table 1.
