■Port Expansion Unit — Each router unit supports up to two Port
Expansion Units.
■Primary Rate Access Unit — Each router unit supports a single Primary
Rate Access unit.
Installing the RAS
1500 System
The RAS 1500 system consists of a Router Unit (RM), Port Expansion Unit
(PEM), and Primary Rate Access Unit (PAU). You can install the RAS 1500
either as part of a stack of equipment or in a standard 19-inch rack.
RAS 1500 installations are limited to a Router Unit and two Port
Expansion Units or a Router Unit and a Primary Rate Access Unit. When
adding a Port Expansion Unit or Primary Rate Access Unit, make sure the
router module operational code is upgraded to match the appropriate
version.
WARNING: To avoid personal injury or damage to the unit, make sure the
stack or rack into which you install RAS 1500 is placed on a stable
surface.
Installing the
RAS 1500 System
in a Stack
Use the following steps to install a Router Unit, Port Expansion Unit, or
Primary Rate Access Unit in a stack:
1Peel each rubber foot from the adhesive sheet and attach it to the
bottom of the unit. Use the circular marks on the bottom of the unit as
guides.
2Place the unit into an existing stack of equipment, or on a smooth, level
surface.
Installing the
RAS 1500 System
in a Rack
Use the following steps to install a Router Unit, Port Expansion Unit, or
Primary Rate Access Unit into a standard 19-inch rack:
For rack installations, do not attach the rubber feet to the unit.
1Fully extend the cable guides on the enclosed mounting brackets.
2Fasten the mounting brackets to both sides of the unit using the enclosed
screws and a Phillips-head screwdriver.

Figure 1-1 Fastening the Mounting Brackets to the Route Unit
3Mount the units in the rack.
RAS 1500 units can be mounted in any order, but for ease of
management, we recommend you install RAS 1500 Router Unit on the
bottom of the stack or rack.
Rack Installation
Guidelines
Follow these guidelines when you install RAS 1500 in a rack.
■Operating Ambient Temperature — If the RAS 1500 is installed in a
closed or multi-unit rack assembly, the operating ambient temperature
of the rack environment may be greater than room ambient
temperature. Therefore, we recommend that you install the
equipment in an environment compatible with the RAS 1500’s
maximum rated ambient temperature. Refer to Appendix C,
“Technical Specifications,” for details.
■Air Flow — Install the RAS 1500 so that the rack has enough air flow
for safe operation.
If the RAS 1500 fails while in a rack, you might have to allow more
spacing between the other equipment in the rack to provide more air
flow.
■Mechanical Loading — To avoid a hazardous condition, mount the
equipment in the rack evenly and place the rack on a stable surface.

Grounding the RAS 1500 1-5
■Circuit Overloading — Make sure the RAS 1500 is properly
connected to the power supply circuit. This circuit should include
overcurrent protection and proper power supply wiring.
■Grounding — Maintain reliable grounding of the rack-mounted
RAS 1500. Do not connect the RAS 1500 to a power supply
connection other than the branch circuit.
Grounding the
RAS 1500
Stack installation of a Router Unit and at least one Port Expansion Unit, or
a Primary Rate Access Unit requires proper grounding. Grounding straps
are enclosed in the accessories kit. Install them as follows:
1Remove one cover screw on Router Unit and the Port Expansion Unit or
Primary Rate Access Unit.
2Install a ground strap between the Router Unit cover and the Port
Expansion Unit/Primary Rate Access Unit cover and reinstall the screws as
shown.
Figure 1-2 Grounding the RAS 1500 (Router Unit and two Port Expansion Units)
I/O Module Refer to the I/O Installation Guide that is shipped with the I/O modules for
installation instructions.
WARNING: The I/O modules are not hot-pluggable. You must have the
power cord disconnected when installing I/O modules in the Router Unit
or Port Expansion Unit.

Powering the
RAS 1500 On or Off
There is no power switch on the RAS 1500. Use the following steps to
power on or power off the units in a RAS 1500 stack.
Powering On the
RAS 1500
To power on the RAS 1500, connect the power cord to the AC power
port of the unit and plug the power cord into the AC power supply
source.
Powering Off the
RAS 1500
To power off the RAS 1500, disconnect the AC power cord from the AC
power port of the unit.
WARNING: Always disconnect the AC power cord before removing the
cover of the Router, Primary Rate Access Unit, or Port Expansion Unit.
Connecting the
STACKNET Cables
After the Router Unit and Port Expansion Unit AC power cords are
connected, connect the STACKNET cable(s). Connect each Port Expansion
Unit or a single Primary Rate Access Unit to the Router Unit making sure
the connection is secure. Note that the ferrite end must be connected to
the Router Unit as shown.
