Foundry Networks LS 648 manual Wiring Map for Serial Cable, 3 Serial Cable Wiring, Switch’s 9-Pin

Installing a FastIron LS Switch

NOTE: You need to run a terminal emulation program on the PC.

2.Open the terminal emulation program and set the session parameters as follows:

•Baud: 9600 bps

•Data bits: 8

•Parity: None

•Stop bits: 1

•Flow control: None

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.

6	9

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.
