For additional information on rollover cable pinouts, see Appendix C "Cabling Specifications."
Step 2 Configure your terminal or PC terminal emulation software for 9600 baud, 8 data bits, no parity, and 2 stop bits. To configure the console port, refer to the Cisco AS5400 Universal Access Server Software Configuration Guide.
To connect a modem to the auxiliary port, follow these steps:
Step 2 Make sure that your modem and the auxiliary port on the access server are configured for the same transmission speed (38400 baud is typical) and hardware flow control with Data Carrier Detect (DCD) and Data Terminal Ready (DTR) operations.
Use a coaxial cable to connect a Timing Signal Generator (TSG) to the BITS port. The BITS port is used for external clocking. See figure 3-14.
Connect to the alarm port as follows:
|
Note Use stranded Number 12 or 14 AWG copper wires to connect to the alarm port connector. |
Step 2 Strip a minimum 1/4 in. (0.625 cm) off the wire insulation to connect the stranded wires to the alarm connector. The maximum insulation strip length is 0.31 in. (0.78 cm).
Step 3 Secure the wires to the alarm connector with screws.
|
Caution The maximum tightening torque on the screws is 7 in.-lb (0.79 N-m). |
Step 4 Connect the wires to strain relief clamps that are inserted into the holes in the ventilation grid.
See Appendix C "Cabling Specifications" for alarm port cable assembly and port pinouts.
The power system is comprised of a fully redundant switching power supply with two AC (or two DC) inputs to the main power modules. Each input, and output, is 100% fully redundant, with dual fans for added reliability.
The output of each power module is rated at 300 watts (nonredundant mode), and is composed of four independent output voltages: 3.3V, 5V, 12V and -12V. AC input units have power factor correction, and low Total Harmonic Distortion. Units which are in redundant mode run at one-half the power capability. If a power supply failure occurs, these units are capable of powering the complete system either at the input side or the DC load side. Power failures are reported through software SNMP alarm traps.
Check the power at your site to ensure that you are receiving "clean" power (free of spikes and noise). Install a power conditioner if necessary.
The access server AC power supply includes the following features:
|
Caution In a DC power supply installation, do not connect the 48 VDC Return to chassis ground at the Cisco AS5400. A single-point ground is recommended at the power distribution rack. |
|
Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. To see translations of the warnings that appear in the publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |

Refer to Figure 3-17 and follow these steps to wire the terminal blocks:
|
Warning The illustration shows the DC power supply terminal block. Wire the DC power supply using the appropriate wire terminations at the wiring end, as illustrated. The proper wiring sequence is ground to ground, return to return, and negative to negative. Note that the ground wire should always be connected first and disconnected last. To see translations of the warnings that appear in the publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
|
Caution In a DC power supply installation do not connect the 48 VDC Return to chassis ground at the Cisco AS5400. A single-point ground is recommended at the power distribution rack. |
Step 2 Strip off a quarter of an inch (1/4 in. [0.625 cm]) of insulation on the safety ground, 48 VDC Return, and -48 VDC input wires.
Step 3 Install the safety grounds (green wire) into the terminal block ground connectors and tighten the locking screws. Ensure that no bare wire is exposed.
|
Note For central office installations, we recommend using a copper 6 AWG green ground wire with one end connected to reliable earth. The other end of the wire should be crimped onto the double-hole lug provided in the installation pack. The lug should be secured to the mating holes on either side of the chassis with the two screws included in the accessory pack. |
|
Caution Do not overtorque the terminal block contact screws. The recommended torque is 5.0 in.-lb (0.56 N-m). |
Step 4 Insert both 48 VDC Return wires into the terminal block positive connectors (+) and tighten the locking screws. Ensure that no bare wire is exposed.
Step 5 Insert both -48 VDC wires into the terminal block negative connectors (-) and tighten the locking screws. Ensure that no bare wire is exposed.
