Cisco Systems Cisco ASR 1006 specs

Note DC input power cables must be connected to the PDU terminal studs in the proper positive (+) and negative (–) polarity. In some cases, the DC cable leads are labeled, which is a relatively safe indication of the polarity. However, you must verify the polarity by measuring the voltage between the DC cable leads. When making the measurement, the positive

(+) lead and the negative (–) lead must always match the (+) and (–) labels on the power distribution unit.

•An earth ground cable is required for each DC PDU. We recommend that you use at least 6-AWG multistrand copper wire. This wire is not available from Cisco Systems; it is available from any commercial cable vendor. The ground wire cable lug should be dual-hole and able to fit over M6 terminal studs at 0.625 inch (15.88mm) centers. Recommended lug terminal wire size Panduit part number:

–LCD8-14A-L for 8AWG wire size

–LCD6-14A-L for 6AWG wire size

Note To avoid hazardous conditions, all components in the area where DC input power is accessible must be properly insulated. Therefore, before installing the DC cable lugs, be sure to insulate the lugs according to the manufacturer’s instructions.

Caution Before you connect DC-input power, you must install the DC power ground leads to the DC power supply.

Obtain these necessary tools and equipment:

•Number 2 Phillips screwdriver

•A 3/16-inch flat-blade screwdriver

Installing the Cisco ASR 1006 Router DC Ground Lugs

To install the grounding lugs on the DC power supply, follow these instructions. Figure 11 (item #6) shows the location of the DC power supply grounding stud.

Step 1 Make certain that the chassis ground is connected before you begin installing the DC power supply.

Step 2 Locate the stud on the DC power supply for the GND connection which must be connected first and follow these steps:

a.Using the grounding lug, replace the washers and Kepnut screw in the following order.

-Flat washer

-Grounding cable lug

-Kepnut screw

b.Tighten the Kepnut screws on the power supply studs.

Step 3 Tighten the Kepnut screw (use the screwdriver to tighten the ground screw in the terminal block to a torque of 20+/–2 in-lbs / 2 per.) to complete the installation. Figure 13 shows the installed DC power supply ground stud.
