9-2 Disabling Auto Negotiation and Reducing the Speed of the Network Inter-
face
By default, the Control Station is delivered with auto-negotiation enabled on the network interface
eri0/nge0/e1000g0. Not all hospital switches (or their ports) support auto-negotiation. In the case that the
hospital switch does not support auto-negotiation, you must disable the network interface eri0/nge0/
e1000g0 auto-negotiation capabilities via a command that includes adv_autoneg_cap 0 (see procedures
below).
Once auto-negotiation is disabled, the network interface eri0/nge0/e1000g0 operates at its fasted possi-
ble speed unless you have disabled that speed before disabling the network interface auto-negotiation
capabilities. If the operating speed of the network interface eri0/nge0/e1000g0 remains greater than that
of the hospital switch port which is connected to Control Station, communication with the hospital net-
work may not be possible.
Table 1 summarizes the different network interface speeds, their probability that they work with the hos-
pital switch, and the command used to disable the appropriate speed. If you are disabling auto-negotia-
tion, you must consult the hospital network administrator to determine the maximum speed supported by
the hospital switch port connected to the Control Station. Any speeds that are not supported by the hos-
pital switch port must be disabled on the network interface eri0/nge0/e1000g0 before disabling the auto-
negotiation capabilities.
