•Rubber feet for setting the Director on a desktop, or rack-mount brackets for mounting the Director in a rack or on a wall (screws not included).
•A cable (not included) for each LAN and WAN interface.
In addition, you might need the following external equipment:
•Console terminal (an ASCII terminal or a PC running terminal emulation software) configured for 9600 baud, 8 data bits, no parity, and 2 stop bits. A terminal is required unless you are using the AutoInstall procedure. See the section "Connecting the Console Terminal and Modem" later in this chapter for instructions on connecting a console terminal.
•Modem for remote access.
Setting Up the Chassis
You can set the chassis on a desktop, install it in a rack, or mount it on a wall or other flat surface. Use the procedure in this section that best meets the needs of your network.
Setting the Chassis on a Desktop
Before setting the Director on a desktop, shelf, or other flat, secure surface, perform the following steps to install the rubber feet:
Step 1 Locate the rubber feet on the black adhesive strip that shipped with the chassis. (See .)
Figure 3-1 Identifying the Rubber Feet
Step 2 Place the Director upside down on a smooth, flat surface.
Step 3 Peel off the rubber feet from the black adhesive strip and place them adhesive-side down onto the five round, recessed areas on the bottom of the chassis. (See .)
Figure 3-2 Installing the Rubber Feet
Step 4 Place the Director right-side up on a flat, smooth, secure surface.
Do not place anything on top of the Director that weighs more than 10 pounds (4.5 kg). Excessive weight on top could damage the chassis.
Rack-Mounting the Chassis
This section describes the procedures for rack-mounting the chassis. The chassis comes with brackets for use with a 19-inch rack or, if specified in your order, optional larger brackets for use with a 24-inch rack. The brackets are shown in .
Figure 3-3 Identifying the Brackets
Attaching the Brackets
To install the chassis in a rack, attach the brackets in one of the following ways:
•With the front panel forward (see Figure 3-4)
•With the rear panel forward (see Figure 3-5)
•In a center-mount telco rack (see Figure 3-6)
Figure 3-4 Bracket Installation—Front Panel Forward
Figure 3-5 Bracket Installation—Rear Panel Forward
Figure 3-6 Telco Bracket Installation—Rear Panel Forward
Installing in a Rack
After the brackets are secured to the chassis, you can rack-mount it. Using the screws you provide, attach the chassis to the rack as shown in .
Figure 3-7 Attaching the Chassis to a Rack (Rear Panel Forward Shown)
Wall-Mounting the Chassis
Use the small brackets (for use with a 19-inch rack) to wall-mount the chassis. The smaller brackets provide the most stable position for the chassis.
Take the following steps to wall-mount the chassis:
Step 1 Attach the brackets as shown in Figure 3-8.
Figure 3-8 Attaching the Wall-Mount Brackets
Step 2 Attach the chassis assembly to the wall as shown in Figure 3-9, using screws and anchors that you provide. We recommend the following:
•For the best support of the chassis and cables, attach the brackets so that the screws align with a vertical wall stud.
•For the best ventilation of the chassis, mount the chassis with the power supply and fan at the top.
To prevent the chassis from pulling away from the wall when cables are attached, align the brackets and screws with a vertical wall stud. (See
Figure 3-9.) To ensure adequate ventilation, make sure there is clearance between the Director and the wall.

Wiring the DC Power Supply
If you ordered a Director with a DC power supply, follow the directions in this section to wire the terminal block.
Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. (To see translated versions of this warning, refer to the appendix ".")
Note This product is intended for installation in restricted access areas and is approved for use with copper conductors only. The installation must comply with all applicable codes.
Take the following steps to wire the terminal block:
Step 1 Attach the appropriate lugs at the wire end of the power supply cord.
Step 2 Wire the DC power supply to the terminal block, as shown in .
The illustration shows the DC power supply terminal block. Wire the DC power supply using the appropriate lugs at the wiring end, as illustrated. The proper wiring sequence is ground to ground, positive to positive (line to L), and negative to negative (neutral to N). Note that the ground wire should always be connected first and disconnected last. (To see translated versions of this warning, refer to the appendix ".")
Figure 3-10 DC Power Supply Connections
When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor. (To see translated versions of this warning, refer to the appendix "
Do not overtorque the terminal block captive thumbscrew or terminal block contact screws. The recommended torque is 8.2
± 0.4 inch-lb.
After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position. (To see translated versions of this warning, refer to the appendix ".")
Connecting to the Network
This section explains how to connect the Director to your network.
The cables required to connect the Director to a network are not provided with the Director. However, cables and transceivers can be ordered from Cisco Systems. For ordering information, refer to the Cisco Product Catalog or contact Cisco customer service. For cable pinouts, refer to the appendix "."
Do not work on the system or connect or disconnect cables during periods of lightning activity. (To see translated versions of this warning, refer to the appendix ".")
Connecting to an Ethernet Network
Use an Ethernet AUI cable to connect the Ethernet AUI port (DB-15) to an Ethernet transceiver, or connect an Ethernet transceiver directly to the Ethernet AUI port. (See .)
Note If your Ethernet connection requires jackscrews, remove the slide-latch assembly from the AUI connector and attach the jackscrews provided.
