Matrix Module

The Matrix Module, which can only be used with Intel 500 Series switches, enables a stack with scalable bandwidth to be established.

Using the Matrix Module
Use the Matrix Module to establish a stack of two to seven switches with scalable bandwidth. A single Matrix Module installed in one of the switches provides six external connections to the other switches in the stack. Each connection can provide a high-speed, full-duplex connection between the switches.

The Primary Switch
The switch with the Matrix Module installed is referred to as the primary switch.

Connecting the Matrix Module
It is recommended that the cables be connected to the Matrix Module ports sequentially, starting with port 1.


LEDs

The matrix module has three LED indicators:


Module LED States


Internal Port Link and Status LEDs

The two LEDs indicate the following.


Individual Ports
The data activity on the individual ports (1 to 6) is shown by the LEDs next to the SIM connector on the secondary switches.

Cabling a Stack with Redundancy
Redundancy ensures that data transfer between switches in a stack continues, even if a cable is removed or an individual module fails. Redundancy is automatic once the Matrix Module is installed and connected correctly.

Implementing Redundancy
Redundancy is only possible in a stack of 520/550 switches. To enable redundancy, a second Matrix Module is required. This must be installed in a second 520/550 switch on the opposite side of the switch from the module installed in the primary switch.

Fall-over time
The fall-over time is less than 0.5 secs.


Example

If the primary switch has the module installed in Slot A, the second Matrix Module must be installed in Slot B.

The primary and secondary switches also require Stack Interface Modules (SIMs) to be installed in the vacant slots. The rest of the switches in the stack require SIMs installed in both Slot A and Slot B.

Mirrored cabling

For redundancy to work, the cables attached to the Matrix Module in the primary switch must be copied and mirrored on the Matrix Module in the secondary switch. Both sides of the stack must be cabled identically.
