2.4 Installing the Optional Emergency Power Supply
To ensure increased reliability for mission-critical applications, the IC35516 can be equipped with a 12 VDC
emergency backup power supply (the IC35-EPS12, sold separately). When installed, the emergency power supply is
in standby mode. Should the primary unit fail, the DC backup automatically switches on and the LED on the front
panel lights. In addition, an SNMP fault notice is sent.
To verify the primary power status, use the
Router#
show system
command. Under System Information, you will
see the power unit status.
System Information

Serial No. :
Power Unit Status = OK
Should the IC35-EPS12 become active due to a fault with the primary power, the unit should be swapped out at the
earliest convenience and sent for repair. The IC35-EPS12 is designed to be a temporary replacement when the
primary power fails, not a permanent replacement.
To install the optional power supply, simply attach the 12 VDC connector of the power supply to the jack located in
the center of the rear panel of the switch. Connect the power cord to the power supply and plug the power cord into
an outlet.
Important!
The optional power supply becomes
HOT
under normal operating conditions. To avoid damage or injury,
set the power supply on a heat-resistant surface and
USE CAUTION
when handling the unit.
2.5 Connecting Power
Important:
Carefully review the power requirements (Chapter 2.1.3) before connecting power to the switch.
Use the following procedure to connect power to the switch:
1. Plug one end of the supplied power cord into the power connector on the back of the switch.
2. Plug the other end into a grounded AC outlet.
3. Turn on the switch’s power. The power LED will begin its initialization process.
The front panel LEDs blink and the power LED illuminates when it has initialized. The switch is ready for connection
to the network.
Important:
If the power does not come on, check the next section to ensure that the correct cabling is used.
2.6 Connecting to the Network
The switch may be connected to an Ethernet network with the switch powered on or off.
Use the following procedure
to make the network connections:
1. Connect the network devices to the switch, following the cable guidelines outlined below.
