Chapter 1: Product Overview
Features and Benefits
The Avocent SPC offers secure AC power management for 8 (SPC800/810) or
16 (SPC1600/1610) attached devices. The SPC can remotely control the power
on/off status for each attached device plus provide measurement and reporting
of the total combined load of all devices for more accurate load management.
Wake-up power sequencing
When the SPC is powered up, each of the power receptacles, or ports, is
powered sequentially with a two-second delay between each port. This power
sequencing staggers the individual loads, eliminating the potential of a blown
fuse or circuit breaker.
Cumulative load measurement
The load measurement feature eliminates guesswork by supplying the
cumulative operating load in amperes. This measurement allows on-site
technicians to install and operate as much equipment as possible on a circuit
without worry. Circuit use is maximized, while effectively leaving a 10% to
20% safety margin. Remote users may also access this information at any time
over an IP connection from the SPC command line or control screen.
Port grouping
For simultaneous operations across multiple attached devices, SPC ports may
be combined in named groups. Operations may then be issued to all ports in
the named group with one easy command sequence.
Easy installation
The SPC ships with mounting brackets for easy rack installation. Vertical units
install on the side of a rack without taking up valuable U-space. Horizontal
units use only 1U (SPC800/810) or 2U (SPC1600/1610) of rack space.
User interfaces and LEDs
The SPC features two types of user interfaces: the command line and the
control screen. For easier port recognition, both individual ports and port
groups may be assigned descriptive names for use in control commands. For
the local technician, LED displays on the SPC indicate individual port power
status and the cumulative power load.
Administrative security and control
The SPC ships with three predefined usernames, including an administrator.
The administrator may create up to 57 additional usernames, each with port and
command access rights. SPC access is further secured through password protection.

4SPC Installer/User Guide
For configurations that require multiple fully-privileged users, administrative
privileges may be granted to other users in the system.
Automatic time-out
When an SPC user ends a session, configuration changes made during the
session are saved. For added system security, a user session will be terminated
automatically after five minutes of inactivity, without saving any configuration
changes made during the session. If a user is called away unexpectedly, an
unprotected channel will not remain open indefinitely.
Configuration reset capability
The SPC may be reset to the factory default configuration through an
administrative level command. If the administrator password is lost or
unavailable, the unit may be reset manually by pressing a reset button on the
SPC unit.
Using the SPC with Avocent Appliances
The SPC user interfaces described in this document are available when a serial
Telnet connection is made to the unit. When an SPC is connected as a device on
an Avocent appliance, these interfaces may be available or other interfaces may
be provided by the Avocent appliance, depending on the configuration. For more
information, see the installer/user guide for the appropriate Avocent appliance.

Component Overview
Figure 2.1 shows portions of a 115V vertical SPC. Horizontal units have the
same components described below.
The RJ-45 serial port is used for the cable connection to an appliance.
The Input Current digital LED indicates the total cumulative load in amperes
(A) of all the devices attached to the SPC ports. The LED readout increases in
0.5A increments up to 9.5A. Above 10A, the LED increases in 1.0A increments.
All SPC models indicate an overload by displaying oL at 30.5A, which is the
maximum rating of the SPC unit without considering the capacity of the cord set.
The SPC800/810 has 8 power output connectors, which are called ports. The
SPC1600/1610 has 16 ports. Each port supplies power to an attached device,
and can be individually turned on and off. See the port specifications in
Appendix B for more information.
An LED adjacent to each port will illuminate when that port is powered.

A letter/number combination is printed near each SPC port. The ports are
labeled A1 through A4, B1 through B4, C1 through C4 and D1 through D4.
These names may be used in commands that require a port name. See Port
Naming in Chapter 3 for more information.
The power input cord connects the SPC to the electrical power source. See
power cord and plug specifications in Appendix B for more information.

Chapter 2: Installation 11
In horizontal units, the “data side” contains the RJ-45 serial port. The
opposite “power side” contains all the other components. You may rack
mount a horizontal unit with either the data side or power side facing the
front of the rack.
Rack Mounting
To rack mount the SPC, first attach the mounting brackets to the unit, then
attach the SPC to your rack.
To rack mount a vertical SPC:
1. Attach one mounting bracket to the top flange of the SPC with one set of
screws and washers through each of the slots in the bracket, as shown in
Figure 2.2. Secure each screw with a nut. The slots allow about 1/2 inch of
vertical adaptability.

2. Repeat with the other mounting bracket on the bottom flange of the SPC.

12 SPC Installer/User Guide
3. Attach the top and bottom brackets to your rack, using the round holes in
each bracket. The round holes may not align with the mounting holes in
your rack. In this case, you may use only one screw and washer set per
bracket to secure the SPC to your rack, as long as both top and bottom
brackets are attached to the rack.
To rack mount a horizontal SPC:
1. Each side of the SPC has multiple bracket mount Pemnuts to
accommodate variable depths. Select the appropriate bracket mounting
point on one side and attach a bracket with two of the screws provided.
2. Repeat with the other mounting bracket on the other side of the unit.
3. Install the unit in your rack, using the slots in each bracket. The slots
allow about 1/4 inch of horizontal adaptability to align with the mounting
holes of your rack.
Connecting the SPC to a CPS
Connect either end of the supplied RJ-45 cable to the connector on the SPC.
Connect the other end to a CPS port.
Connecting the SPC to the Power Source
Depending on the model number, units are shipped with different power cord
configurations and arrangements.
• For a unit with a power cord attached to the SPC and fitted with a plug,
direct connection to the power source is allowed.
• For a unit supplied with a detachable power cord, the power cord must be
first attached to the SPC and then to the power source.
• A unit with a power cord attached but without a plug (unterminated)
requires qualified service personnel to select and install the appropriate
plug before attaching the SPC to the power source.
Each port powers up sequentially, with a two-second delay between each port,
eliminating a potential blown primary fuse or circuit breaker.
To attach a detachable 230V power cord to the 230V SPC unit:
1. Plug the female end of the power cord firmly into its connector on the SPC.
2. Use a screwdriver to tighten the two screws on the retention bracket.
To connect the SPC to the power source:
Plug the male end of the SPC power cord into the AC power source.

Chapter 2: Installation 13
Connecting Devices to the SPC
To avoid the possibility of noise due to arcing:
Keep the device’s on/off switch in the off position until after it is plugged into
the SPC port.
- or -
Log in to the SPC and turn the ports off before connecting the devices to the
SPC. After connecting the devices, turn them on using the SPC.
On 115V units, connect devices to the SPC ports. On 230V units, install a
retention clip on each port. Pull the open prongs out slightly and insert them
into holes on the sides of the SPC adjacent to the port. Then insert the device’s
power cord and gently snap the retention clip over the cord.
It is recommended that the attached devices be evenly distributed across all
available outlets to avoid exceeding outlet ratings limitations.
WARNING: The SPC and all attached devices should be powered down before servicing the
unit. Always disconnect the power cord from the wall outlet.
