The EIA/TIA 232 serial communication port serves as a connection point for management by a PC or SNMP
workstation. Foundry switches come with a standard male DB-9 connector, shown in Figure 3.11.

Serial Port (DB-9 DTE) Pin-Out
Most PC serial ports also require a cable with a female DB-9 connector.
Terminal connections will vary, requiring either a DB-9 or DB-25 connector, male or female.
Serial cable options between a Foundry switch or router and a PC or terminal are shown in Table 3.3.
