Powering on the Router
This chapter describes how to connect the power modules in the chassis and to power on the router.
•Power Supply Overview, on page 1
•Power Connection Guidelines for AC-Powered Systems, on page 2
•Connect AC Power to the Chassis, on page 3
•Connect a DC Power Supply to the Chassis, on page 14
Power Supply Overview
You can install up to four 3.2KW AC or 3.2KW DC power supplies in the chassis. Ensure that all power
connection wiring conforms that to the rules and regulations in the National Electrical Code (NEC) and in
local codes.
The Cisco 8608 chassis doesn't support a mix of AC and DC Power Supply Units (PSUs).
Note
AC Power Module
• The AC power modules are single feed with 3.2KW capacity at 220V. They also support operation at
110V with half the capacity of 1570W.
• AC power modules are rated at 3.2KW maximum at 230V AC high line input, and 1570W maximum at
115V AC low line input.
• AC nominal range: 100—120V AC and 200—240V AC
• AC full range: 85—132 V AC and 180—264V AC; with extended range to 300V AC
DC Power Module
• The DC power modules are dual feed with 3.2KW capacity at any specified input voltage. DC power
modules with single feed at any specified input voltage provide up to 1.6KW maximum capacity.
• DC nominal range: -48 to -60VDC
• DC full range: -40 to -75VDC

Power Connection Guidelines for AC-Powered Systems
When connecting AC-input Power Supply Units (PSUs) to the site power source, observe the guidelines
described here.
Statement 1028—More Than One Power Supply
This unit might have more than one power supply connection. To reduce risk of electric shock, remove all
connections to de-energize the unit.
Warning
• Ensure that the AC-input power supply module has a detachable power cord.
• Each chassis power supply should have a separate, dedicated branch circuit.
• North America
• PSU3.2KW-ACPI only—Power supply modules require a 20 A circuit.
• International—Circuits should be sized according to local and national codes.
• If you are using a 208 or 240 VAC power source in North America, note that such lines are considered
hot and the circuit must be protected by a two-pole circuit breaker.
Statement 1005—Circuit Breaker
This product relies on the building’s installation for short-circuit (overcurrent)
protection. To reduce risk of electric shock or fire, ensure that the protective
device is rated not greater than:
Warning
• 20 A circuit breaker for an AC-input power supply module.
•50 A DC-rated circuit breaker for each input of a DC-input power supply module, for safety purposes
- irrespective of whether the inputs are power from a single or separate DC sources.
This product requires short-circuit (overcurrent) protection, to be provided as
part of the building installation. Install only in accordance with national and local
wiring regulations. Statement 1045

Power Connection Guidelines for AC-Powered Systems

Statement 1022—Disconnect Device
To reduce risk of electric shock and fire, a readily accessible two-poled disconnect
device must be incorporated in the fixed wiring.
Warning
• The source AC outlet must be within 9.84 to 14 feet (3.0 to 4.293 meters) of the system - depending on
the length of the power cord, and should be easily accessible.
• The AC power receptacles used to plug in the chassis must be the grounding type. The grounding
conductors that connect to the receptacles should connect to protective earth ground at the service
equipment level.

Statement 1030—Equipment Installation
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Warning
Statement 1017—Restricted Area
This unit is intended for installation in restricted access areas. Only skilled, instructed, or qualified personnel
can access a restricted access area.
Warning
Statement 1005—Circuit Breaker
This product relies on the building’s installation for short-circuit (overcurrent) protection. To reduce risk of
electric shock or fire, ensure that the protective device is rated not greater than:
AC: 20A, DC: 50A
Warning
Statement 1028—More Than One Power Supply
This unit might have more than one power supply connection. To reduce risk of electric shock, remove all
connections to de-energize the unit.

Statement 1003—DC Power Disconnection
To reduce risk of electric shock or personal injury, disconnect DC power before removing or replacing
components or performing upgrades.
Warning
Statement 1046—Installing or Replacing the Unit
To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be
made first and disconnected last.
Warning
Statement 1022—Disconnect Device
To reduce risk of electric shock and fire, a readily accessible two-poled disconnect device must be incorporated
in the fixed wiring.
Warning
Statement 1025—Use Copper Conductors Only
To reduce risk of fire, use copper conductors only.
Warning
Statement 1018—Supply Circuit
To reduce risk of electric shock and fire, take care when connecting units to the supply circuit so that wiring
is not overloaded.
Warning
Statement 1029—Blank Faceplates and Cover Panels
Blank faceplates and cover panels serve three important functions: they reduce the risk of electric shock and
fire, they contain electromagnetic interference (EMI) that might disrupt other equipment, and they direct the
flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers,
and rear covers are in place.
Warning
The chassis relies on the protective devices in the building installation to protect against short circuit,
overcurrent, and ground faults. Ensure that the protective devices comply with local and national electrical
codes.
Caution

Powering on the Router
Connect AC Power to the Chassis

We recommend that you occupy all power supply slots of the router with power supplies. In case a power
module fails, it is recommended to retain the failed power module in its slot until it is replaced with a new
power module. This recommendation ensures that the system airflow is not impacted adversely, which may
then result in the overheating of the router and its components.
Note
A dual pole breaker is needed for installation. For determining the recommended breaker size, please adhere
to local and national rules and regulations. The breaker size is based on the specifications of the product for
the current drawn and the specified voltage level.
Note
Procedure
Step 1 Verify that the AC cable is installed in the correct AC source and outlet type.
Step 2 Set the AC-input power supply switch to the OFF (0) position.
Figure 1: Power Switch in Off Position
Power supply in the OFF (0) position1
Step 3 Grasp the power supply handle with one hand and place your other hand underneath to support the bottom of
the PSU. Slide the PSU all the way into the power supply bay. Ensure that the PSU is fully seated in the bay.

When correctly installed, the latch on the PSU locks-in the module, to avoid accidental removal of the module.

Step 4 Verify that all site power and grounding requirements have been met.
Step 5 Verify that you have the correct AC power cord for your location and power supply rating and only then plug
the power cord connector into the power supply AC-in receptacle.

This section shows how to correctly operate the power cord retainer, to tighten or loosen it while installing
or removing the power supply unit.
Some of the illustrations do not include the power supply module, for the sake of clarity. The retainer is
otherwise permanently fixed to the power supply module.

Installation and Removal Sequence
Installation—After you have inserted the power supply unit into the bay, first position the clamp closest to
the power supply, near the plug round cylinder stress relief and then insert the flexible retainer strip into the
clamp hole and tighten. The clamp cannot be moved after the flexible retainer strip is inserted into the clamp
hole.
Removal—After you have turned off the power supply unit's rocker switch, first remove the flexible retainer
strip from the clamp hole and then adjust the position of the clamp to remove the power cord.
Positioning the Clamp
In figure, Figure 5: Positioning the Clamp, the clamp can always move freely in direction 3a. To move the
clamp in direction 3b, use a flathead screwdriver or similar device and push the clamp latch down. The figure,
