There is a small pin hole (Figure 1) to the left of the LEDs that provides access to the manual reset button. To manually reboot the device, insert a small object such as the tip of a pen, and push inward. A slight press of the manual reset button reboots the device.
|
Note When you reset a SwitchProbe device, all counters are cleared to
zero. Any changes you made to the device settings (using the Agent
Configuration Utility) since the previous reset take effect. You can also reset the device using the Reset Agent option of the Agent Configuration Utility. For more information about this option, see the chapter "Initializing a SwitchProbe Device" in the Cisco SwitchProbe Installation and Configuration Guide. |
The following sections describe the interfaces on the DS-3 Frame SwitchProbe device:
|
Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. |
DS-3 Frame SwitchProbe devices contain the following two network interface cards (NICs).
|
Note The interface location is a logical representation, not always the physical slot location in the chassis. |
The default mode of this interface (manage) allows the SwitchProbe device to communicate on the network. You can change the mode of the Ethernet interface using the Agent Configuration Utility.
|
Note To ensure optimum performance, Cisco Systems recommends that you maintain the interface in manage mode |
For information about configuring network interfaces, see the chapter "Configuring SwitchProbe Devices" in the Cisco SwitchProbe Installation and Configuration Guide.
For information about the Agent Configuration Utility, see these sources of information:
The Ethernet interface (interface 1) supports 10Base2 (Thinnet), 10Base5 (Thicknet), or 10BaseT unshielded twisted pair (UTP). The factory configuration is indicated on the front panel with an appropriate label. The connector for each topology is as follows:
Interface 1 is designed to communicate with the TrafficDirector application in manage mode, but you can configure the interface to simultaneously track network traffic and communicate with the TrafficDirector application in manage and monitor mode.
For information about configuring network interfaces, see the chapter "Configuring SwitchProbe Devices" in the Cisco SwitchProbe Installation and Configuration Guide.
For information about the Agent Configuration Utility, see these sources of information:
This interface supports DS-3 only. The physical DS-3 Frame interface has a DB-15 connector that attaches to the DS-3 tap, and four LEDs. The DS-3 Frame interface operates in monitor mode only (tracking network traffic).
The Peripheral Controller Card (PCC), always designated as interface 2, has the following three external components:
This 9-pin, male, D-type connector supports RS-232 signals.
Table 2 shows the console and remote port specifications.
| Port Setting | Specification |
|---|---|
Line rate | 9600 bps (default) |
Line code | ASYNC |
Line interface | EIA/TIA-232 |
No. of bits | 8 |
No. of stop bits | 1 |
Parity | None |
You can only use the remote port to exchange management data to and from an attached device such as a management station or a modem. You must configure the remote port to manage mode. You can use the remote port as the secondary management port if communication with the primary management port is lost.
|
Note You cannot use the remote port to monitor a network segment. |
To adjust the baud rate of the remote port, see the chapter "Physical Description" in the Cisco SwitchProbe Installation and Configuration Guide.
The port has a 9-pin male, D-type connector that supports RS-232 signals. When you configure the device (set IP address, gateway address, network mask, and so on) using an ASCII terminal, you must connect that terminal to this port. For more information about configuring the device using an ASCII terminal, see the chapter "Initializing a SwitchProbe Device" in the Cisco SwitchProbe Installation and Configuration Guide.
|
Note You cannot use the console port to monitor a network segment. |
Use the null-modem cable to connect the console port to the ASCII terminal. For a sample wiring diagram, see the appendix "Cable Pinouts" in the Cisco SwitchProbe Installation and Configuration Guide.
|
Note EIA/TIA-232 and EIA/TIA-530 were known as recommended standards RS-232 and RS-530 before acceptance as standards by the Electronic Industries Association (EIA) and Telecommunications Industry Association (TIA). |
You use the configurable DIP switches (labeled SW1) between the console and remote ports to adjust the baud rate of the console port and set the boot mode of the device.
Table 3 shows the DIP switch settings.
| Switch | Setting | Result |
|---|---|---|
1 | Off (default) | Boot from flash memory |
2 | Off (default) | Reserved |
3, 4 | 3 = off | Console port = 1200 bps |
3 = off | Console port = 2400 bps | |
3 = on (default) | Console port = 9600 bps | |
3 = on | Console port = 19200 bps |
|
Note Cisco SwitchProbe devices ship with the latest version of agent
firmware loaded in both EPROM and flash memory. If an updated
version becomes available, you might need to upgrade the agent
firmware. For information about updating the firmware, see the
chapter "Configuring SwitchProbe Devices" in the Cisco
SwitchProbe Installation and Configuration Guide. Because SwitchProbe devices boot from flash memory by default, all upgraded agent firmware is written to flash memory. Regardless of any upgrade, the factory-installed, original version of agent firmware remains in the EPROM. Therefore, if a firmware upgrade fails, you can force the device to boot from the EPROM by setting DIP switch 1 to on. The agent will boot from the EPROM and use the original version of firmware. If the flash becomes corrupted, the agent automatically boots from EPROM, regardless of the setting of DIP switch 1. |

|
Warning This equipment is to be installed and maintained by service personnel only as defined by AS/NZS 3260 Clause 1.2.14.3 Service Personnel. |
|
Warning The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open. |
|
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. |
To connect a DS-3 Frame SwitchProbe device to the network segment, see the following sections:
The Ethernet interface supports Thicknet, Thinnet, or unshielded twisted pair (UTP) cable types; the device is set to one of the three types when it is manufactured. A label in the lower portion of the device front panel indicates the factory-set configuration.
Table 6 describes the label and corresponding connection.
| If the Label States... | You Connect |
|---|---|
Configured for AUI | A Thicknet (10Base5) cable to the Thicknet connector. |
Configured for BNC | A Thinnet (10Base2) cable to the Thinnet connector. |
Configured for UTP | A UTP cable to the RJ-45 UTP connector. |
Connecting a DS-3 Frame interface to a full-duplex network segment is a two-stage process:
|
Note The DS-3 tap is a passive device that presents high impedance to the link. Therefore, you can connect and disconnect the DS-3 Frame SwitchProbe device from the tap without disrupting the integrity of the link being monitored. |
To connect the DS-3 tap to the DS-3 Frame SwitchProbe device:
Step 1 Locate the 15-foot cable (with a male DB-15 connector at one end and a female DB-15 connector at the other end) that is shipped with the tap.
Step 2 Plug the female connector of this cable into the DS-3 Frame interface.
Step 3 Plug the other end of the 15-foot cable (the end with the male DB-15 connector) into the female DB-15 port of the DS-3 tap.
To connect the DS-3 tap to the network:
Step 1 Locate the two cables that connect one DS-3 Frame switch, server, or router to another DS-3 Frame switch, server, or router.
Step 2 Unplug these two cables from one of the two DS-3 Frame devices.
Step 3 Plug the ends of these two cables into the two ports labeled IN on the DS-3 tap.
(The device plugged into the two IN ports is the DTE device).
Step 4 Locate two six-foot cables (with BNC connectors at each end) that are shipped with the SwitchProbe device.
Step 5 Plug one end of each of these cables into the two ports labeled OUT on the
DS-3 tap.
Step 6 Plug the remaining connector on each of these cables into the DS-3 Frame device from which you unplugged the cables in Step 2. (The device plugged into the two OUT ports on the tap is the DCE device.)
Step 7 See Figure 7 to confirm that the new cabling setup reestablished the connections you had previously.
To connect the DS-3 Frame SwitchProbe device to a power source:
Step 1 Using the AC power cord included with the device, connect one end of the cord to the power socket.
|
Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. |
Step 2 Connect the other end of the AC power cord to a suitable power source.
|
Note Depending on the voltage applied from the power source, the power supply automatically switches to the appropriate condition. |
You can connect a management device to the DS-3 Frame SwitchProbe device in one of two ways:
The DS-3 Frame SwitchProbe device supports out-of-band management through the serial port (labeled Remote) using SLIP or through the Ethernet interface.
You can use the SLIP connection as a secondary connection through which you access all network statistics. The SLIP link is normally used as a backup link when the network is not operational or when the agent is not accessible.
To perform out-of-band management through the active Ethernet interface:
Step 1 Connect an Ethernet cable to the active Ethernet interface.
Step 2 Configure the interface mode to manage.
The DS-3 Frame SwitchProbe device supports side-band management (manage and monitor mode on the same interface) through the active Ethernet interface of the device.
To make a side-band connection:
Step 1 Connect an Ethernet cable to the active Ethernet interface.
Step 2 Configure the interface mode to manage and monitor.
The Cisco SwitchProbe Installation and Configuration Guide (shipped with all Cisco SwitchProbe devices) explains the basic configuration process. Read and follow the instructions in that guide to configure the agent firmware in your SwitchProbe device.
