The DS-3 ATM SwitchProbe device is designed to operate in a normal office environment and can be placed on a table or mounted in an equipment rack near the network segment it serves. The site must be equipped with the following:
| Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). |
Before beginning the installation process, read the following installation cautions and warnings:
| Warning The safety cover is an integral part of the product. Do not operate the unit without the safety cover installed. Operating the unit without the cover in place will invalidate the safety approvals and pose a risk of fire and electrical hazards. |
| Warning Read the installation instructions before you connect the system to its power source. |
| Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. |
| Warning Ultimate disposal of this product should be handled according to all national laws and regulations. |
| Warning The device is designed to work with TN power systems. |
| Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord. |
| Warning To prevent the device from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 104° F (40° C). To prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance around the ventilation openings. |
| Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety: |

This section describes the physical features of the DS-3 ATM SwitchProbe device.
The DS-3 ATM SwitchProbe device is housed in rack-mountable, front-access chassis that measures 17 inches wide, by 16.5 inches deep, by 5.25 inches high (43.18cm wide by 41.91cm deep by 13.34cm high). You can mount this device in a 19-inch equipment rack. For instructions on mounting the device in a rack, see the installation chapter in the Cisco SwitchProbe Installation and Configuration Guide.
The following sections describe each area of the DS-3 ATM SwitchProbe devices:
Figure 1 shows the front panel of the DS-3 ATM SwitchProbe device.
The following sections describe the elements on the front panel of the DS-3 ATM SwitchProbe device:
Table 1 describes the four LEDs on the top left of the chassis front panel.
| LED Label | LED Color | Status | Meaning |
|---|---|---|---|
POWER | Green | On | Proper power is being supplied to the device. This LED is normally on. |
Off | Proper power is not being supplied to the device. | ||
FAULT | Red | On or | Hardware or software error in the device. |
Off | Device is working properly. | ||
|
| Reserved for future diagnostic use. | |
ACTIVITY | Amber | On | Heavy network traffic. |
| Blinking | Moderate network traffic. | |

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.
The following sections describe the interfaces on the DS-3 ATM SwitchProbe device:
DS-3 ATM SwitchProbe devices contain the following two network interface cards (NICs).
The Peripheral Controller Card (PCC), always designated as interface 2, has the following three external components:
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 |

Fourth | Green | Off | Not used. |
Figure 3 shows the ATM interface LEDs.
Figure 4 shows the rear panel of a DS-3 ATM SwitchProbe device.
The power switch is on the upper right of the rear panel of the device.
| Caution To avoid damaging the device, you cannot turn the power off for four seconds after you turn the power on. |
The power socket is located on the lower right rear panel of the DS-3 ATM SwitchProbe device. The power socket has three metal prongs.
Each DS-3 ATM SwitchProbe device is equipped with an AC power cord for connection to an appropriate power source. To connect the device to a power source, see "Connecting a DS-3 ATM SwitchProbe Device to a Power Source."
Before connecting this device to the network, note the following warnings:
| 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 ATM SwitchProbe device to the network segment, see the following sections:
The Ethernet interface supports either Thicknet, Thinnet, or unshielded twisted pair (UTP) cable types; the device is set to one of the three types during manufacture. A label in the lower portion of the device front panel indicates the factory-set configuration.
Table 5 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 ATM interface to a full-duplex network segment is a two-stage process:
To connect the DS-3 ATM tap to the DS-3 ATM SwitchProbe device, see Figure 5 and follow these steps:
Step 2 Plug the female connector of this cable into port 1 on the DS-3 ATM interface (port 1 is the ATM port).
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 ATM tap.
To connect the DS-3 ATM tap to the network, see Figure 6 and follow these steps:
Step 2 Unplug these two cables from one of the two DS-3 ATM devices.
Step 3 Plug the ends of these two cables into the two ports labeled IN on the DS-3 ATM tap.
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 ATM tap.
Step 6 Plug the remaining connector on each of these cables into the DS-3 ATM device from which you unplugged cables in Step 2.
Step 7 See Figure 7 to confirm that the new cabling setup reestablished the connections you had previously.
To connect a DS-3 ATM SwitchProbe device to a power source, follow these steps:
| 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.
| Caution To prevent any possible damage to the device, and to ensure that it operates correctly, never use the Power Out socket. |
You can connect a management device to the DS-3 ATM SwitchProbe device using either of these methods:
