Foundry FastIron LS Layer 2 Compact Switch Hardware Installation Guide

10 Gigabit Ethernet Module Slots

These switches include two slots on the rear panel for single-port 10GBASE uplink modules with XFP transceivers, and a single port CX4 module. The 10GBASE transceivers operate at 10 Gbps full duplex with support for asymmetric flow control (that is, the port honors incoming pause frames, but does not originate pause frames).

10 Gbps CX4 Ports

This section describes the 10-GbE CX4 module.

10-GbE CX4 Module

The single-port CX4 module is installed in the FLS624 and FLS648 (shown in Figure 2.6). You can order the FastIron LS with a single-port CX4 module installed at the factory, or you can later upgrade your device. This module is a 10-GbE-CX4 Ethernet uplink card. It can perform data transmission directly through copper links to 15m(extended 30m) in length.

The following single-port CX4 module is supported:

•single-port CX4 uplinks for 10-Gigabit.

Link and Activity LEDs on the module faceplates indicate operational status:

•If the Lnk LED is on, the port is connected. If the Lnk LED is off, no connection exists, or the link is down.

•If the Act LED is on or blinking, traffic is being transmitted and received on the port. If the Act LED is off, no traffic is being transmitted or received on the port.

When this module is installed, the show media command returns the following display:

Cable Specifications for New Module

The following cable specifications apply to the CX4 port, which is included in the new 10GbE interface module (FLS-1XGC):

•Support for 802.3ak or 10 Gigabit Ethernet CX4 standard

•Support of up to 15m in length

•Requires latch-style receptacle or SFF-8470 plug

•Recommended CX4 cable: Manufactured by WL Gore, part number IBN6600-15, CX4 Assembly - 26AWG SPC 15.0m

NOTE: The recommended CX4 cable can also be used with a Small Form Factor Pluggable (XFP) MSA- compliant optical transceiver (part number FGS-2XGC).

Figure 2.7 shows the CX4-grade cable.
