A Remote Management Switch with Modem (part number SW556A [includes 33.6 kbps modem] or SW556AE [includes 56 kbps modem]) is also available.
8 REMOTE MANAGEMENT SWITCH 3. Installation 3.1 Master and Switched Ports Connect the Remote Management Switch’s ports A through D found on the rear of the unit to your RS-232 devices. Each port uses a DB25 subminiature connector and supports the following leads for asynchronous communications.
9 CHAPTER 3: Installation The four switched ports, A through D, are wired DCE (output data on pin 3, RD). The master port is wired as DTE. To directly connect a terminal device to the master port, you need a null-modem cable (see Figure 3-2). Figure 3-2.

Part number SW556A features a 33.6-kbps modem, while part number SW556AE incorporates a 56-kbps modem. Connect the modem to the dial line via an RS-232 to modular adapter (included).
12 REMOTE MANAGEMENT SWITCH 4. Operation 4.1 Four Modes of Operation You can operate the Remote Management Switch in four possible ways: menu selection, escape code sequences, lead control, and manual control.
13 CHAPTER 4: Operation The Remote Management Switch automatically detects the rate of operation, allowing connection at 300 bps to 115.2 kbps. Using the default speed will allow the fastest access to the unit. To invoke the auto rate detector, press the Enter key one or more times as needed.
14 REMOTE MANAGEMENT SWITCH At this point, the master port is connected through to the port selected. The Remote Management Switch is passive to the messages sent between the master port and the port selected.
