Installation Manual

20 Installing the Switch

To install a module, follow the steps below:

Step Task

If the system is on, save the running configuration, if desi

red (and different from the startup configuration) with

the command write memory. Then power down the system by unplugging it from its power source.

2 Use a #2 Phillips screwdriver to remove either a module facep

late or an existing module. Note that these slots,

when used for 10G Ethernet ports, are assigned port numbers from left to right as you face the front of the

system. So, for clarity in programming those ports, you might favor the left-most slot for the first 10G module

that you install.

3 Grasping the module faceplate, remove the module from its packaging and slide it into the slot until the module

faceplate

is flush with the rear cover of the system.

4 Secure the captive screws on either side of the module.

5 XFP: Usin

g the optical XFP 10-Gigabit module (catalog name S50-01-10GE-2P) requires additional XFP

transceiver inserts, which are not included in the module kit (see Installing XFPs on page 46

or the installation

instructions that come with the transceiver). The CX4

module (catalog name S50-01-10GE-2C) ports do not

require inserts.

CX4: Usin

g a CX4 module requires using CX4 cables that are approved for the target device. Cables are not

part of the module kit, but they are orderable from Force10. For details, see Using CX4 Cables (CX4 Cable

Matrix) in the S-Series tech tips on iSupport:

https://www.force10networks.com/CSPortal20/KnowledgeBase/ToolTipsSSeries.aspx

When using cables substantially shorter or longer than 5 meters, use the cx4-cable-length command to set

the signal strength. Use cx4-cable-length long for a longer cable, cx4-cable-length short for a shorter

cable. For details, see the Interfaces chapter in the FTOS Command Reference.

You can connect a CX4 cable to an XFP po

rt through a CX4 XFP converter (catalog name GP- XFP-1CX4) in

the slot. However, an XFP port does not support the use of the cx4-cable-length command, discussed next.

Do not connect CX4 ports to 12G stack ports in the switch. The re

ceptacles and cables are the same, but they are

incompatible. CX4 ports are labeled as such; stack ports are not labeled.

For details on enabling ports, see the FT

OS Configuration Guide.

Caution: Hotswapping (inserting or removing) a module can crash and lock up the system, requiring

a power cycle.
