Tools Required

Make sure that you have the following standard tools before beginning the installation:

• ESD-preventive wrist straps for each person

• Number 2 Phillips screwdriver

• Socket wrench set

• Standard clippers or knife (to cut packaging binding)

• Tape measure

• Level (Optional)

Hardware Required

The Cisco MGX 8260 chassis mounts in a standard 19- or 23-inch equipment rack. Before starting the installation procedure, check that you have the necessary hardware components. The solution this procedure describes uses the components shown in Table 2-1.

Table 2-1: Hardware Requirements

Cisco Part Number	Description	Quantity1
MGX8260	Cisco MGX 8260 chassis and accessory kit	1
SCC5FC-4FE	SCC-5Gbps Front Card, 4 100BaseT Broadband Ports	1
SCCBC-4FE	SCC-Back Card with NMS Ports and 4 100BaseT Network Interfaces	1
BSCFC-6T3	BSC-Front Card for 3/1/0 TDM Switching of 6 DS3 Channels	4
T3E3BC-6DSX	T3-Back Card for 6 (TX and RX) SMB Female DS3 Interfaces	4
AC-DC-EXTPSS	Cisco MGX 8260 Power Supply (Optional)	1

1Quantities include one redundant BSC circuit card.

Hardware Component Spacing

The spacing between hardware components is important for the following reasons.

• Cabling is provided for some configurations and works for only certain vertical and horizontal orientations of the equipment.

• Vertical space is required above certain host computers to allow access to the circuit cards that are located inside the computer.

Install the plenum over the uppermost Cisco MGX 8260 chassis in the rack.

Installing the Chassis

To install the chassis, follow these steps:

Note The chassis is typically empty. Do not insert or remove cards at this time.

Step 2 Using the mounting brackets and twelve screws, mount the chassis in the equipment rack (see Figure 2-2).

Step 3 At the rear of the chassis, connect a protective ground wire to the chassis ground terminals near the A or B supply (see Figure 2-3). Use a #10 RING LUG for 16-14 AWG wire. Where practical, use a ground lug that spans a pair of ground terminals.

Installing the Exhaust Plenum

The exhaust plenum is a Cisco MGX 8260 accessory that assures proper airflow through the chassis when other equipment is mounted above it. Although the plenum primarily controls airflow, it also protects the internal components from falling objects or other physical damage. You install the exhaust plenum over the top-most Cisco MGX 8260 in a one or two-chassis configuration; you do not need the plenum for a rack with three Cisco MGX 8260s.

To install the exhaust plenum, follow these steps:

Step 2 Place the plenum over the top Cisco MGX 8260 chassis in the rack (see Figure 2-5).

Installing Front Cards

The Cisco MGX 8260 chassis holds front and back cards. Start installing cards from the front.

Warning Observe standard electrostatic discharge (ESD) precautions before handling, inserting, or removing cards.

To install front cards, follow these steps:

Step 2 From the front of the chassis, install an SCC card in slot 9 (see Figure 2-6). Holding the card with the extraction levers straight out, slide the card into the slot and seat it firmly in the backplane.

Warning Handle the card gently. Bending or forcing the card can cause permanent damage.

Installing Back Cards

To install back cards, follow these steps:

Step 2 From the rear of the chassis, install an SCC back card in slot 9 (see Figure 2-7).
