Installing the Supervisor Engine

Catalyst 4500 series and Catalyst 4500 E-series switches have horizontal chassis slots that are numbered

from top to bottom. On the Catalyst 4503, 4503-E, Catalyst 4506, and 4506-E switches, you can install

the supervisor engine only in slot 1. On the Catalyst 4507R switch, you install the primary supervisor

engine in slot 1, and you can install an optional redundant supervisor engine in slot 2. On the Catalyst

4507R-E switch, you install the primary supervisor engine in slot 3, and you can install an optional

redundant supervisor engine in slot 4. The supervisor engines in a redundant system must be of the same

type.

Hazardous voltage or energy is present on the backplane when the system is operating. Use caution

Warning

when servicing. Statement 1034

To prevent ESD damage, handle supervisor engines by the carrier edges only.

Caution

To install a supervisor engine in a Catalyst 4500 E-series switch, follow this procedure:

Take the necessary precautions to prevent ESD damage as described in the installation guide for your

Step 1

switch.

Ensure that you have enough clearance to accommodate any interface equipment that you will connect

Step 2

directly to the supervisor engine ports.

Loosen the captive installation screws that secure the switching-module filler plate or the existing

Step 3

supervisor engine (whichever is present) and remove it.

Step 4

Remove the supervisor engine filler plate or the existing supervisor engine from slot 1. If a switching

module filler plate was installed, save it for future use. If you are removing an existing supervisor engine,

see the

To install the new supervisor engine, grasp the switching module front panel with one hand and place

Step 5

your other hand under the carrier to support the supervisor engine, as shown in

the printed circuit boards or connector pins.

Align the edges of the supervisor engine carrier with the slot guides on the sides of the switch chassis,

Step 6

as shown in

OL-19334-02

Place a removed component board-side-up on an antistatic surface or in a static shielding container.

If you plan to return the component to the factory, immediately place it in a static shielding

container.

Avoid contact between the printed circuit boards and clothing. The wrist strap only protects

components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

Never attempt to remove the printed circuit board from the metal carrier.
