Replacing the Inter-Chassis Link Cables

ICL ports can be used only with an ICL license. After the addition or removal of a license, the license enforcement is performed on the ICL ports only when the portdisable and portenable commands are issued on the ports. An ICL license must be installed on both Brocade Backbones forming the ICL connection. The backbones can be either two PowerConnect B-DCX units, two PowerConnect B-DCX-4S units, or one DCX and one DCX-4S or any combination of three backbones of either type.

Time required

The replacement procedure for an ICL cable takes less than five minutes.

Items required

Replacement ICL cable

Figure 1 shows an ICL cable. The ICL cables (2 meters long) and the ICL connectors (Figure 1) are color-coded and

labeled for ease of installation.Figure 2 through Figure 9 show the acceptable cabling configurations for the inter-chassis link (ICL) feature. Connect the ICL cables in one of the configurations shown.

ATTENTION

To prevent the latch mechanism from wear, use the color-coded (green) latch-release tab for cable removal. Pull the

ICL 0

tab to disengage the retention latch before cable removal.

Removing an ICL cable

1. Using the latch release tabs, pull each plug on the cable from its respective receptacle on the core switch blades (CR4S-8).

2. Repeat for each cable that requires replacement.

Replacing an ICL cable

1. Align the color-coded and labeled (ICL 1 and ICL 0) plugs on either end of the ICL cable with their respective connectors on the core switch blades (either CR8 blades in the DCX or CR4S-8 blades in the DCX-4S).

2. Push each plug in until the latch mechanism clicks into place. Follow the steps in one of the two procedures below to install the ICL cables.

For a two-DCX installation:

a. Connect the cables from the top connectors (ICL 1) of the CR8 blades in the first chassis to the bottom

connectors (ICL 0) of the CR8 blades in the second chassis.

b. Connect the cables from the bottom connectors (ICL 0) of the CR8 blades in the first chassis to the top

connectors (ICL 1) of the CR8 blades in the second chassis.

For a two-DCX-4S installation remember that the blades in the DCX-4S are installed horizontally, so the usual top-to-bottom orientation becomes a left-to-right orientation:

a. Connect the cables from the top connectors (ICL 1) of the CR4S-8 blades in the first chassis to the bottom

connectors (ICL 0) of the CR4S-8 blades in the second chassis.

b. Connect the cables from the bottom connectors (ICL 0) of the CR4S-8 blades in the first chassis to the top

connectors (ICL 1) of the CR4S-8 blades in the second chassis.

For a DCX-to-DCX-4S installation keep in mind that top and left are the same as are bottom and right when you move from the connectors on the DCX to the DCX-4S.

3. Repeat steps 1 and 2 for each cable that requires replacement.
