	Installation
	Connecting the Probe
	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”

z“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.
