Getting to Know Your IOLAN
Rack Mount Models
DC Power Requirements
The IOLAN DC is supplied with an integral Terminal Connections block to facilitate connection to a
DC source(s). The DC supply(s) should have adequate over-current protection within the closed rack
system and comply with local or national standards applicable to the installation territory. You need
wire gauge 20 to 22 AWG to connect the IOLAN rack mount unit to the power source.

AC Power Requirements
AC power rack mount units come with standard power cords, specific to your country, that should be
used to power the IOLAN unit.

Getting to Know Your IOLAN
This section describes the hardware components found on your IOLAN unit.
Overview
All IOLANs have the same basic hardware components to allow you to connect to serial devices,
connect to the network, monitor LAN and serial activity, and manage the unit. Below is a list of these
components:

z
Power/Ready—This LED can cycle through several colors (yellow, green, red) during a boot
process, but should complete with a green light. When the IOLAN has completed the power up
cycle, the LED will be steady green on rack mount modes. On desktop models, if the LED is
green after power up but continues to cycle on and off (flashes green), this indicates that the
console switch is in the on position. You can learn more about the Power/Ready LED in
