Connecting the Probe
59
2. Connect the HSSI cable to the left-most HSSI connector on the HSSI
WanProbe.
3. Connect the new HSSI cable between the DSU/CSU and the right-most
connector on the HSSI WanProbe.
NOTE
The HSSI cable should be a straight-through cable. Part numbers: Cisco Systems
CAB-HSI1 or ADC/Kentrox 96010011—10ft. HSSI cables.
In this connection scheme, the probe monitors network traffic as if the signal
between the DTE and DCE is sent straight-through the probe.
Connecting to the Serial Port (Out-of-Band)
Out-of-Band communications with the probe are conducted through the serial
port, not over the network. This mode of communications is optional.
The following methods are available for Out-of-Band connections:
“Direct Connection”
“Modem Connection” on page 60
“Data Switch Connection” on page 65
Direct Connection
To make a direct connection to the probe, connect the NetMetrix management
station’s serial port to the probe’s RS-232C port using a null modem cable
(Agilent part number 24542G—9-to-25 pin, or equivalent). Figure 3-12 shows
the direct connection to the probe.
