The DT-24+ or DE-30+ modules are hardware devices that are used with Cisco CallManager to interface Cisco IP phones to the Internet. The DT-24+ or DE-30+ module is installed in a Personal Computer (PC) Server.
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy, and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at the user's expense.
The following sections describe the installation procedures for the DT-24+ or DE-30+ module.
Electrostatic discharge (ESD) damage occurs when electronic cards or components are improperly handled and can result in complete or intermittent failures. Follow these guidelines to prevent ESD damage:
| Caution Periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms). |
Avoid contact between the modules and clothing. The wrist strap protects only the card from ESD voltages on the body; ESD voltages on clothing can still cause damage.
| Warning
Only trained and qualified personnel should be allowed to install or replace this equipment. |
| Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. |
| 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. |
| Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. |
| Warning Before working on a system that has a standby or off switch, turn off the power by pressing the switch and unplug the power cord(s). |
| Warning The port labeled "Ethernet" is a safety extra-low voltage (SELV) circuit. SELV circuits should only be connected to other SELV circuits. Because the T1/E1 circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits. |
| Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself. |
| Warning
The DE-30+ must be used with an IEC60950/EN60950 approved CSU/DSU. |
| 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 E1 interface card may only be installed in an ACA-permitted customer equipment or a Data Terminal Equipment (DTE) that is exempted from ACA's permit requirements. The customer equipment must only be housed in a cabinet that has screw-down lids to stop user access to overvoltages on the customer equipment. The customer equipment has circuitry that may have telecommunications network voltages on them. |
| Warning
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. |
| 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. |
| Caution Electronic components on printed circuit boards are extremely sensitive to static electricity. Normal amounts of static electricity generated by clothing can damage electronic equipment. To reduce the risk of damage due to electrostatic discharge, it is recommended when installing electronic equipment, that anti-static grounding straps and mats are used. |
The DT-24+ or DE-30+ module is installed in a 32-bit Personal Computer Interface (PCI) slot in a PC desktop or server chassis. The DT-24+ or DE-30+ module only requires power and reset signal from the PC chassis.
Use the manufacturer's installation instructions and the following steps to install the DT-24+ or DE-30+ module in a PCI slot in a PC server chassis.
Step 1 End all applications running on the PC and turn the power switch off.
Step 2 Remove the power cord from the PC. If the PC has more than one power cord, remove all of the power cords.
Step 3 Remove the PC chassis cover.
Step 4 Choose an available PCI slot and remove its blank rear bracket. Save the mounting screw for Step 7.
Step 5 Locate the supplied PCI retainer and 2 screws. Secure the retainer to the edge of the DT-24+ or the DE-30+ module.
Step 6 Insert the DT-24+ or DE-30+ module into the chosen PCI slot. Ensure that the rear bracket of the DT-24+ or DE-30+ module fits correctly into the opening in the rear panel of the PC's chassis. Check to see if the edge of the PCI retainer was inserted properly into the PCI slot.
Step 7 Secure the rear bracket of the DT-24+ or DE-30+ module into the chassis frame with the screw that was removed in Step 4. This will also ensure chassis ground to the DT-24+ or DE-30+ module.
Step 8 Replace and secure the PC's cover.
Step 9 Select the appropriate network interface cable for connecting to the DT-24+ or DE-30+ module.
Step 10 Return power to the PC.
Step 11 Restart the applications.
Step 12 Follow the instructions in the Cisco CallManager application for any software configuration of the module.
There are four LEDs on the face plate and four LEDs on the component side of the printed circuit board. See Table 1 for a description of the LEDs on the face plate and Table 2 for a description of the LEDs on the printed circuit board.
