Router Installation

Before you Begin

This chapter guides you through the installation of the D-Link DI-1750 Series Router. It covers unpacking, safety precautions, required tools, case installation, power connection, console/auxiliary port connection, Ethernet interface connection, and WAN/Voice interface card connection.

Unpacking the Router

Verify that the package contains: one DI-1750 Router, one 100-240V AC power cord, one Console Cable (DRC-0001), a rack mount kit, and this Installation Guide. Contact your local D-Link Reseller if any items are missing or damaged.

Safety Warnings & Recommendations

• Maintain a clear, dry, safe, and dust-free environment.
• Avoid pulling power supply and interface cables forcefully.
• Use a Standard Power Surge suppressor for AC mains power.
• A UPS is recommended for continuous power.
• Wear safety glasses when working in potentially hazardous conditions.
• Do not touch uncovered telephone-network cables directly.
• Do not insert telephone-network cable connectors into Ethernet/Fast Ethernet ports.
• Avoid working on the system or connecting/disconnecting cables during lightning activity.
• Ensure correct cable types (RJ-45 for Console/Auxiliary/Ethernet, ISDN and Ethernet cables are distinct).

Tools and Equipment Required for Installation

• Screwdriver
• ESD-preventive wrist strap
• Appropriate connecting cables
• Console cable
• Power supply cable
• Terminal

Installing the Router Case

The router can be placed on a desktop or mounted in a 19" rack. Ensure cable jacks are accessible, LED indicators are visible, and ventilation holes are unobstructed.

• On a Table: Place on a smooth, secured table, ensuring access to power and communication cables. Do not place heavy objects on the router.
• In a 19" Rack: Use the provided brackets. Ensure the front panel faces forward. Secure the router to the rack using the brackets.

Connecting Power to the Router

• Recommended AC Power Socket: Use a three-pin power socket with a neutral point connector or a dedicated computer power socket. Ensure the neutral point of the building's power supply system is reliably grounded.
• Connecting AC Power Cord:
  • Confirm the GND wire is correctly grounded.
  • Ensure the router's power switch is OFF.
  • Connect the power cord to the router's rear panel AC input socket and the AC outlet.
  • Switch the power switch to the ON position.
  • Verify the PWR LED on the front panel is ON.

Connecting to the Console & Auxiliary Port of the Router

Console Port

The Console port (RJ45) supports transmission rates from 1200bps to 115200bps. It requires a dedicated Console cable (DRC-0001) to connect to a terminal device (like VT-100) or a PC's serial port. Use a terminal emulator (e.g., Windows HyperTerminal) with the following settings: Rate: 9600bps, Data bits: 8, Stop bit: 1, Parity: None, Flow control: None.

The pin details for the Console port are:

• 1: CD (Carrier Detect)
• 2: RXD (Receive)
• 3: DSR (Data Send Ready)
• 4: TXD (Transmit)
• 5: RTS (Request to Send)
• 7: DTR (Data Ready)
• 8: SG (Signal Ground)

The DRC-0001 cable connects the Console port to a terminal or PC serial port (DB25 or DB9).

AUX Port-Auxiliary Port

The AUX Port (RJ45) supports transmission rates from 1200bps to 115200bps. It can be connected to an asynchronous modem for remote console configuration or as a backup link. Recommended settings: Rate: 115200bps, Data bits: 8, Stop bit: 1, Parity: None, Flow control: None.

The auxiliary cable (DRC-0011) connects the AUX Port to an external asynchronous modem using RJ45 to DB25 or DB9 connectors.

Connecting the Fast Ethernet Interface

The Fast Ethernet port (RJ45) supports 10/100 Mbps auto-negotiation. Connect a Hub/Switch using a CAT5 UTP/STP cable. The UTP pin numbering is standard.

• UTP Port Pin Description:
• 1: TPTXD+ (Transmit+)
• 2: TPTXD- (Transmit-)
• 3: TPRXD+ (Receive+)
• 6: TPRXD- (Receive-)

To connect directly to a single host computer, a UTP cross-over cable can be used. For multiple computers, an Ethernet Hub or switch is required. Cable connections should comply with EIA/TIA 568A/B standards.

Installing WAN Interface Cards

Ensure the router is powered OFF and the power cord is removed before installing interface cards. Use ESD-preventive measures.

1. Power OFF the router and ground the chassis.
2. Remove all network and telephone cables.
3. Remove the blank filler panel from the desired slot using a flat-blade screwdriver.
4. Align the module with the chassis guides and slide it into the slot.
5. Push the module until the edge connector is seated securely. Align captive screws with chassis holes.
6. Secure the module with captive mounting screws.
7. Refer to the Interface Card Hardware Installation Manual for detailed procedures.
8. Configure router parameters using the Software Configuration Guide.
