3.3 ESR-1000, ESR-1200, ESR-1500, ESR-1511, ESR-1700, ESR-3100,ESR-3200 power module
installation
ESR-1000/1200/1500/1511/1700/3100/3200 routers can operate with one or two power modules. The
second power module installation is necessary when the device operates under strict reliability requirements.
From the electric point of view, both places for power module installation are identical. In the context of device
operation, the power module can be in the main and reserve slot. For information on priority see table
'Description of connectors, LEDs and controls located on router'. Power modules can be inserted and removed
without powering the device off. When additional power module is inserted or removed, the router continues
operation without reboot.

The state of power modules can be checked by the indication on the front panel of the router (see Light
indicationsection) or by diagnostics, available through the router management interfaces.
3.4 Connection to Power Supply
Ground the case of the device prior to connecting it to the power supply. An insulated multiconductor
wire should be used for earthing. The device grounding and the earthing wire cross-section should
comply with Electric Installation Code.
If a PC or another device is supposed to be connected to the router console port, the device should be
also securely grounded.
Connect the power supply cable to the device. Depending on the delivery package, the device can be
powered by AC or DC electrical network. To connect the device to AC power supply, use the cable from
the delivery package. To connect the device to DC power supply, use wires with a minimum cross-
section of 1 mm
2
.
Turn the device on and check the front panel LEDs to make sure the terminal is in normal operating
conditions.
Power module fault indication may be caused not only by the module failure, but also by the absence
of the primary power supply.
