Warning
This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any
equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for
preventing accidents.
Only trained and qualified personnel should install, replace, or service this equipment.
Read the installation instructions before you connect the system to its power source.
This unit is intended for installation in restricted access areas. A restricted access area is where access can only
be gained by service personnel through the use of a special tool, lock and key, or other means of security, and is
controlled by the authority responsible for the location.
Voltage is present on the backplane when the system is operating. To reduce risk of an electric shock, keep hands
and fingers out of the power supply bays and backplane areas.
Do not work on the system or connect or disconnect cables during periods of lightning activity.
Warning
Before beginning the installation of the SCE8000, read the Regulatory Compliance and Safety Information for the
Cisco SCE8000 Platform document.
Site Preparation
• Verify that the power service at the site is suitable for the SCE8000 chassis.
• Print out and have accessible the Site Planning Checklist and the Cisco SCE8000 Installation Checklist, both found in the
Cisco SCE8000 Installation and Configuration Guide, for recording information about this installation.

Step 4 Install the eight (four per side) 12-24 x 3/4-inch or 10-32 x 3/4-inch screws through the holes in the bracket and into
the threaded holes in the equipment rack posts.
Step 5 Use a tape measure and level to verify that the chassis is installed straight and level.
Installing an Optical Bypass Module
There are two installation options for the external bypass modules:
• Chassis mount panel—This panel is mounted on slot #4 of the SCE8000 chassis. It hosts two optical bypass modules, which
will serve the two traffic links supported by one Cisco SCE8000 chassis.
• External mounting panel—This panel can be mounted in any 19" rack. It hosts up to four optical bypass modules, which
will serve the four traffic links supported by two Cisco SCE8000 platforms.
Step 1 For external mounting, install the external mounting panel in the 19" rack. Screw the mounting panel to the rack using
four 3/4-inch screws, two on each side, through the holes in the mounting panel and into the threaded holes in the rack
posts.
For internal mounting, the SCE8000 chassis will be shipped with the chassis mounting panel already installed in slot #4.
Step 2 Remove the module filler plate covering the subslot in the mounting panel by loosening the two screws.
6
Step 3 Carefully insert the optical bypass module into the subslot (there are no guide rails) and tighten the captive screws on
either side of the module.

3 Connect the Power Supply Units
.The SCE8000 chassis is shipped with the power supplies (AC or DC) already installed. This section provides information for
grounding the SCE8000 platform and connecting the AC or DC power supply units
Connect the Chassis Ground
Note You must connect the system ground on both AC- and DC-powered systems to an earth ground if this equipment is
installed in a US or European Central Office.
Note For DC-powered systems, the system ground is also the power supply ground. The DC ground must be installed with
a permanent connection to an earth ground according to NEC guidelines.
Note There are additional grounding requirements when using the PWR-2700-DC/4 power supply in the Cisco SCE8000
chassis.
Two threaded M4 holes are provided on the chassis frame to attach the ground cable.
You must complete this procedure before connecting system power or turning on the Cisco SCE8000 chassis.
Step 1 Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the covering from the end of the grounding
wire.
Step 2 Insert the stripped end of the grounding wire into the open end of the grounding lug.
Step 3 Use the manufacturer recommended crimping tool to secure the grounding wire in place in the grounding lug.
Step 4 Locate and remove the adhesive label from the system grounding pad on the chassis.

Note The DC return must remain isolated from the system frame and chassis (DC-I).
Warning
Note As the power requirement of the SCE8000 will not exceed 1350W, it is not necessary to connect two pairs of input wires
Note For multiple DC input power supply, each DC input must be protected by dedicated circuit breaker or fuse. The circuit
Step 1 Power supply ground is required. Install the PWR-2700-DC/4 power supply ground as described in this procedure.
Before performing any of the following procedures, ensure that power is removed from the DC circuit.
to each power supply. Should it be desired to connect two pairs of input wires, both pairs of input wires for one 2700W
DC-input power supply must come from the same battery system (A feed); and both pairs of input wires for the other
power supply must come from another battery system (B feed).
breaker or fuse should be sized according to the power supply input rating and local or national electrical code
requirements.
Note The system ground connection with the PWR-2700-DC/4 power supply in a Cisco SCE8000 is provided by the
PWR-2700-DC/4 power supply ground. Additionally, you can connect a system (earth) ground.
Note You must always connect the PWR-2700-DC/4 power supply ground.
Note You must always connect the PWR-2700-DC/4 power supply ground for both power supplies.
Note If you intend to use an additional system (earth ground), ensure that the system ground connection has been
made. For ground connection installation instructions, see Connect the Chassis Ground, page 8.
Step 2 Remove the plastic bag attached to the front panel and put aside. This bag contains two plastic terminal block barriers,
two cable ties, and two cable holder covers.
