7. If applicable, lock the wheels of the lift.
8. Gently slide the chassis onto the final installation surface, ensuring that it remains supported during the
transfer.
9. Ensure the chassis can be oriented so that the nonport side has access to intake air (cool).
10. Reinstall the vertical cable management fingers.
11. If ICL cables are not being used, ensure that EMI plugs are inserted in the ICL cable sockets in the core switch
blades.
12. Reinstall the chassis door. The door must be installed to meet EMI compliance.
Providing power to the Brocade DCX-4S
DANGER
Use the supplied power cords. Ensure the facility power receptacle is the correct type, supplies the
required voltage, and is properly grounded. (D004)
1. Connect the two AC power cords to each of the two power supplies.
2. Connect the power cords to a power source with a voltage of 200 to 240 VAC, 47 to 63 Hz.
3. Turn the AC power switches on the power supplies to ON. The AC power switches light green when switched on
and power is supplied.
4. The Brocade DCX-4S performs a power-on self-test (POST) each time it is powered on. POST takes approximately
ten minutes and is complete when the indicator light activity displays the operational state.
You can bypass POST by using the fastBoot command. You can also disable POST for successive reboots on the
Brocade DCX-4S using the diagDisablePost command.
ATTENTION
Do not connect the switch to the network until the IP addresses are configured.
Managing cables
ATTENTION
The minimum bend radius for a 50 micron cable is 2 in. under full tensile load and 1.2 in. with no tensile load.
Cables can be organized and managed in a variety of ways: for example, using cable channels on the port or nonport
sides of the cabinet or patch panels to minimize cable management. With the horizontal orientation of the blades in
the DCX-4S, a pair of vertical cable management finger assemblies (Figure 4) have been provided to keep the cables
from hanging down in front of other blades.
Following is a list of recommendations:
•Leave at least 1 m (3.28 ft) of slack for each port cable. This provides room to remove and replace the
Brocade DCX-4S, allows for inadvertent movement of the rack, and helps prevent the cables from being
bent to less than the minimum bend radius.

Publication Number: 53-1001192-03
•If ISL Trunking is in use, group the cables by trunking group. The ports are color-coded to indicate which
ports can be used in the same ISL Trunking group: eight ports marked with solid black ovals alternate with
eight ports marked with oval outlines.
•For easier maintenance, label the fiber optic cables and record the devices to which they are connected.
•Route the cables to both the left and right sides of the DCX-4S through the cable management fingers.
•Keep LEDs visible by routing port cables and other cables away from the LEDs.
FIGURE 4 Vertical cable management finger assemblies
Installing ICL cables (optional)
NOTE
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
Brocade DCX-4S units or one DCX-4S and one Brocade DCX.
Follow this procedure to install the inter-chassis link (ICL) cables. Refer to the Fabric OS Administrator’s Guide for the
configuration procedure and requirements.
Figure 5 shows an ICL cable. The ICL cables (2 meters long) and the ICL connectors are color-coded and labeled for
ease of installation.Figure 6 and Figure 7 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
tab to disengage the retention latch before cable removal.

Publication Number: 53-1001192-03
ATTENTION
Since the blades in the DCX-4S are installed horizontally, the usual top-to-bottom orientation becomes a left-to-right
orientation.
Connect the cables from the left (top) connectors (ICL 1) of the CR4S-8 blades in the first chassis to the right (bottom)
connectors (ICL 0) of the CR4S-8 blades in the second chassis.
Similarly, connect the cables from the right (bottom) connectors (ICL 0) of the CR4S-8 blades in the first chassis to
the left (top) connectors (ICL 1) of the CR4S-8 blades in the second chassis.
NOTE
The cables can cross between the slot 3 CR4S-8 blade on the first chassis and the slot 6 CR4S-8 blade on the second
chassis as long as the left-to-right (top-to-bottom) rule is followed.

swDir:admin> reboot
5. Type reboot to reboot the Brocade DCX-4S.
6. You can use the serial port to monitor error messages through the serial connection. If the serial port is no
longer required, use the logout command to log out of the serial console, remove the serial cable, and replace
the plug in the serial port.
Establishing an Ethernet connection
NOTE
Connecting the CP blades to a private network/VLAN is recommended.
After using a serial connection to configure the IP addresses for the Brocade DCX-4S, you can connect the active CP
blade to the local area network (LAN).
By establishing an Ethernet connection, you can complete the Brocade DCX-4S configuration using either a serial
session, Telnet, or a management application such as Web Tools or DCFM. To create an Ethernet connection to the
Brocade DCX-4S, follow these steps.
1. Remove the shipping plug from the Ethernet port on the active CP blade.
2. Insert one end of an Ethernet cable into the Ethernet port.
3. Connect the other end to an Ethernet 10/100/1000 BaseT LAN.
The Brocade DCX-4S can be accessed through a remote connection using any of the management tools, such as
Telnet, Web Tools, or DCFM.
4. To complete any additional Brocade DCX-4S configuration procedures through a Telnet session, log in to the
Brocade DCX-4S by Telnet, using the admin login. The default password is password.
Customizing a switch name
The switch name of the Brocade DCX-4S can be up to 15 characters long; it can include alpha, numeric, and
underscore characters; and must begin with an alpha character.
NOTE
Changing the name causes a domain address format RSCN to be issued.
1. Type switchName followed by the new name in quotes.
swDir:admin> switchName "swModularSwitch5"
Committing configuration...
Done.
swModularSwitch5:admin>
2. Record the new name for reference.

Setting the Domain ID
Each switch in the fabric must have a unique domain ID. The domain ID can be manually set through the configure
command or can be automatically set. The default domain ID for the Brocade DCX-4S is “1”. Use the fabricShow
command to view the already assigned domain IDs.
1. Enter switchDisable to disable the Brocade DCX-4S.
2. Enter configure.
3. Enter yat the “Fabric parameters” prompt:
Fabric parameters (yes, y, no, n): [no] y
4. Enter a unique domain ID:
Domain: (1.239) [1] 3
5. Complete the remaining prompts or press Ctrl+D to accept the settings and exit.
6. Enter switchEnable to re-enable the Brocade DCX-4S.
Verifying the PID mode and connecting to the fabric
Before connecting the Brocade DCX-4S to the fabric, verify that the port identifier (PID) mode on the Brocade DCX-4S
matches the other switches in the fabric. This parameter must be identical for all switches in the fabric.
Perform the following steps to connect the Brocade DCX-4S to the fabric.
1. Add SFP optical transceivers (or XFP optical transceivers with FC10-6 port card installed) and cables to the Fibre
Channel ports.
The ports are color-coded to indicate which can be used in the same port group for trunking (trunking port
groups can be up to 8 ports). The ports and cables used in trunking groups must meet specific requirements.
Refer to the Fabric OS Administrator’s Guide for information about configuring trunking.
2. Position one of the optical transceivers so that the key is oriented correctly to the port. Insert the transceiver into
the port until it is firmly seated and the latching mechanism clicks.
Transceivers are keyed so that they can only be inserted with the correct orientation. If a transceiver does not
slide in easily, ensure that it is correctly oriented.
3. Position a cable so that the key (the ridge on one side of the cable connector) is aligned with the slot in the
transceiver. Insert the cable into the transceiver until the latching mechanism clicks.
Cables are keyed so that they can be inserted in only one way. If a cable does not slide in easily, ensure that it is
correctly oriented.
4. Repeat step 1 through step 3 for the remaining ports.
5. Organize the cables using the vertical cable management fingers.
6. Verify Brocade DCX-4S and port status using the switchShow command.
7. Verify fabric connectivity using the fabricShow command.

Enabling software licenses
Depending on the vendor agreement, certain licenses are factory installed on the Brocade DCX-4S. To determine
which licenses are enabled, use the licenseShow command.
swDir:admin> licenseshow
AAbbccDDeeFFeeGG:
Web license
Zoning license
Extended Fabric license
Fabric Watch license
Performance Monitor license
Trunking license
Security license
In this example, the license key is AAbbccDDeeFFeeGG. Keep a copy of the license key for reference.
The 64-bit chassis ID is required to obtain and activate licenses for the Brocade DCX-4S. The chassis ID is available
through the licenseIdShow command. The licenseShow and licenseIdShow commands must be entered on the
active CP blade. Refer to the Fabric OS Administrator’s Guide for more information.
Backing up the configuration
Save all key configuration data for the Brocade DCX-4S, including license key information, and upload it to a host for
reference. Routine backups of the configuration are recommended to ensure the current configuration is available.
1. Log on to the switch by Telnet, using the admin account.
2. After zoning configurations and other changes are complete, back up the configuration by typing configUpload
at the prompt. This command uploads the Brocade DCX-4S configuration to the server so that it is available for
downloading to a replacement Brocade DCX-4S.
3. Run the following commands to save the configuration to a file on a secure host.
•configShow
•ipaddrShow
•licenseShow
•switchShow
Alternatively, you can save the configuration file to a Brocade USB.
Keep copies of key data such as passwords, license keys, and IP addresses in a secure location.
NOTE
Passwords are not saved in the configuration file, and are not uploaded during a configUpload.
