BPS-120 User’s Guide
2.3Attaching Power Cables and Connector Definition
The BPS-120 includes power connections for up to six (6) external devices. The rear connector pin-out diagram and power signal descriptions are shown in the following Figure 5, and Table 1 for OUTPUTs (1-6). Backup power is supplied by inserting power cables into any of the OUTPUTs (1-6) on the rear panel of the BPS- 120 and into the corresponding power input connector of device(s) such as switches or routers. The power connector cables may be inserted only one way. There is no need to worry about inserting the power cables incorrectly as they are keyed for one position.
Backup power for externally connected devices is supplied based upon output port priority, with OUTPUT 1 having the highest priority. That is, an external device connected to OUTPUT 1 has backup power priority over devices connected to OUTPUTs 2-6. OUTPUT 2 has backup power priority over devices connected to OUTPUTs 3-6, etc.
To turn the BPS-120 on, connect the power line cord to a 100/240 VAC power outlet and move the rocker switch on the rear panel from the “0” to “1” position. The STANDBY, PWR, TEMP, and FAN LEDs will then light on the front panel. If they do not light up see Table 5 for troubleshooting information.
