Determining the Maximum Speed Supported by Hospital Switch
If the hospital network engineer does not know the maximum speed supported by the hospital network
switch, use the following steps to determine the maximum speed supported by the hospital network
switch:
1. Ask the hospital network engineer for an IP address of a known node on the network that is alive and
reachable by a network ping command.
2. From behind the Browser, launch a command window (see
Launching a Command Line Window
A command window appears with an ADS prompt.
3. Log in as root as follows:
a. At the ADS prompt enter:
su -
b. When requested to specify the root password, enter:
operator
4. Disable the Senographe firewall, by entering:
/etc/rc2.d/S65ipfboot stop
5. Set the eri0/nge0/e1000g0 interface auto-negotiation capabilities to no (i.e. 0) as follows:
For V1/V2 Control Stations, enter:
ndd -set /dev/eri adv_autoneg_cap 0
For V3 Control Stations, enter:
ndd -set /dev/nge0 adv_autoneg_cap 0
For V4 Control Stations, enter:
ndd -set /dev/e1000g0 adv_autoneg_cap 0
6. Ping the IP address given to you by the hospital network engineer, by entering:
ping
<ip address>
•
If the ping test works, all speeds are supported and only auto-negotiation is not supported.
•
If the ping test fails, the highest supported speed needs determining - go to step 7 for V3/V4 Con-
trol Stations or go to step 11 for V1/V2 Control Stations.
7. Disable 1000 Mbit/s Full Duplex as follows:
For V3 Control Stations, enter:
ndd -set /dev/nge0 adv_1000fdx_cap 0
For V4 Control Stations, enter:
ndd -set /dev/e1000g0 adv_1000fdx_cap 0
8. Ping the IP address given to you by the hospital network engineer, by entering:
ping
<ip address>
•
If the ping test works, the highest speed supported is 1000 Mbit/s Half Duplex on V3 Control Sta-
tions or 100 Mbits/S Full Duplex on V4 Control Stations.
•
If the ping test fails, the highest supported speed needs determining - go to step 9.
9. Disable 1000 Mbit/s Half Duplex, as follows:
For V3 Control Stations, enter:
ndd -set /dev/nge0 adv_1000hdx_cap 0
For V4 Control Stations, 1000 Mbit/s Half Duplex is not supported and the Network Interface Card
already has 1000 Mbit/s Half Duplex disabled.
10. Ping the IP address given to you by the hospital network engineer, by entering:
ping
<ip address>
•
If the ping test works, the highest speed supported is 100 Mbit/s Full Duplex.
•
If the ping test fails, the highest supported speed needs determining - go to step 11.
