Serial Null Modem Cable Connections (VMware ESX Systems)
To connect ftServer systems running ftSSS for VMware vSphere to a management PC,
do one of the following:

Locate the system and management PC within reach of the null modem cable that
connects them.

Locate the system so that the null modem cable can reach a serial-port
concentrator that is connected to a management PC.
Table 5-4 describes the null modem cable you must provide.
Telephone Line Connections
The system requires up to two telephone cables, and related connection points:

One telephone line for use when calling for service

One analog telephone line to connect the ASN modem, if used, to a telephone
connection point
A 7-ft (2.13m) telephone cable is shipped with the modem assembly.

N O T E
A dedicated phone line provides the most reliable service
for ASN connections. ASN calls routed through a PBX
might be slow due to the load on the PBX, or might not
complete successfully because the calls can become
disconnected. If you must use a PBX, do not route the
telephone extension through a switchboard; instead,
provide a direct-dial analog number.
