I/O Modules

The Switch 8800 provides slots for five to twelve I/O modules, in addition to the

Fabric slots. The following I/O modules are supported:

1-Port 10GBASE-X (XENPAK) Module

2-Port 10GBASE-X (XFP) Module

12-Port 1000BASE-X (SFP) Module

24-Port 1000BASE-X (SFP) Module

24-Port 10/100/1000BASE-T (RJ45) Module

Consider the following when selecting I/O modules:

You can configure several I/O modules of the same type

All I/O module slots are the same and any combination of I/O modules can be inserted

You must select I/O module port cables that are compatible with each installed I/O module

1-Port 10GBASE-X The 1-port 10GBASE-X (XENPAK) module provides a single 10 Gbps XENPAK port.

14 CHAPTER 1: SWITCH 8800 COMPONENTS

Power Supply

The Switch 8800 power supplies are installed at the bottom of the chassis, in the

 

front. Only one AC power supply is required for each Switch 8800 chassis,

 

although 2 power supply slots are provided to implement 1+1 redundancy.

 

The 7-slot chassis uses a 1200 W auto-ranging power supply (3C17506).

 

The 10and 14-slot chassis use a 2000 W auto-ranging power supply (3C17507).

 

When this power supply is used at 110 V, it delivers 1200 W of power, when used

 

at 220 V, it delivers 2000 W of power.

 

Do not combine 1200 W and 2000 W power supplies in the same chassis. If you

 

have two power supplies in your Switch 8800 chassis, they must be of the same

 

type.

 

Figure 7 illustrates the 1200 W power supply for the Switch 8800.

Power Cords In North America, power cords for both 110 V and 220 V power input are shipped with the Switch 8800 chassis. The power cord required depends on the power output demands of the system.

Table 24 lists the power cord type that is required for each power supply.

The North American 220 V power cord that is provided has a NEMA 6-20P 20A/250VAC style plug. The 220 VAC wall outlet needed for this plug is a NEMA 6-20R 20A/250V style outlet.

Fan Assembly

The fan assembly consists of four to six individual fans and is located on the right

 

side of the chassis. They operate on -48 V DC current. Each starter kit includes the

 

appropriate fan assembly. Figure 8 illustrates the faceplate of the fan assembly for

 

the 7-slot chassis.

Preparing to Install

General Safety

Recommendations

This section provides guidelines for preparing your site and switch for installation.

Before installing your switch, note the following safety recommendations:

Switch off the power supply before connecting the cables.

Keep the switch away from heat sources.

Do not keep the switch in a damp place, and prevent liquid from getting into the switch.

Ensure that the neutral point of the power is grounded properly, to avoid personal injury.

Ensure that the power is off before plugging or unplugging the modules and cables of the switch.

Before moving the chassis, disconnect all the power cords and external cables.

To avoid damage to the switch, connect all the cables correctly. Never connect telephone cables (including the ISDN lines) to the console or AUX port.

During the installation, wear an antistatic wrist strap and antistatic gloves. See “Static Electricity” on page 21 for additional information on preventing static.
