ESD precautions

The PowerConnect B-DCX-4S contains electrostatic discharge (ESD) sensitive FRUs. When working with any PowerConnect B-DCX-4S FRU, use correct ESD procedures.

• Wear a wrist grounding strap connected to chassis ground (if the PowerConnect B-DCX-4S is plugged in) or a

bench ground.

• Store ESD-sensitive components in antistatic packaging.

Replacing a PowerConnect B-DCX-4S Chassis

This section describes how to remove and replace the PowerConnect B-DCX-4S chassis (with its backplane). The basic steps are:

1. Verifying need for replacement

2. Recording critical PowerConnect B-DCX-4S and SAN information

3. Disconnecting from the network and fabric

4. Removing components from the chassis

5. Installing the replacement chassis

6. Installing components into the new chassis

7. Verifying correct operation of system

8. Reconnecting the system to the network and fabric

9. Verifying correct configuration of the fabric

The PowerConnect B-DCX-4S must be removed from the fabric and powered off to perform this procedure. Contact your support provider if you have any questions about whether the chassis requires replacement.

Time required

The chassis replacement takes approximately 3 hours.

Items required

NOTE

The following items are required for the chassis replacement:

• Electrostatic discharge (ESD) grounding strap

• ESD grounding pads for protecting all blades and WWN cards

• Serial cable and workstation computer with a terminal emulator application (such as HyperTerminal for Windows

systems or TIP for Solaris systems), required only if serial console session used

• Pallet jack or hydraulic or assisted lift that raises a minimum of 55 in. (140 cm) and carries a minimum of 250

lb (113 kg)

• A surface to place the old chassis on, such as a second lift or the pallet originally provided with the old chassis

• #2 Phillips screwdriver

Verifying need for replacement

Verify that replacement of the chassis is necessary. Ensure that the components are firmly seated when troubleshooting, and contact your support provider with any questions about whether the chassis should be replaced.

Any of the following events might indicate the need to replace the chassis:

• Visible mechanical damage to the chassis, including damage to sheet metal or card guides that prevents correct

installation of a blade.

• Bent or damaged connectors on the backplane (the surface inside the chassis to which the blades connect).

• One or more components (such as a power supply, blower assembly, port blade, control processor blade (CP8),

core switch blade (CR4S-8), or WWN card) do not function properly even after the component was replaced.

• The psShow or fanShow commands continue to show a faulty component even though the component was

replaced.

• The slotShow command continues to show a faulty control processor (CP8), core switch (CR4S-8), or port blade

even though the blade was replaced.

Recording critical PowerConnect B-DCX-4S and SAN information

All commands must be entered from a CLI session (Telnet or serial) to the active CP blade unless otherwise indicated.

Run supportshow which includes all of the information in Tabl e 1 and more.

For detailed information about Fabric OS commands, refer to the Fabric OS Command Reference. Use a checklist (Table 1) to ensure that all required information is recorded.

1. Open a Telnet session and log in to the PowerConnect B-DCX-4S as admin. The default password is password. Enable the logging function on your Telnet or serial console connection.

2. Back up the current configuration.

• Enter configUpload; then, enter the requested information at the prompts.

This command uploads the PowerConnect B-DCX-4S configuration to the customer-defined FTP server, making it available for downloading. For more information about this command, refer to the Fabric OS Command Reference.

• Alternatively, you can save the configuration file to a Brocade USB.

3. Record the WWN value: Enter wwn; then, copy the command output into a file named “config-miscinfo.txt” on a workstation.

switch:admin> wwn 10:00:00:60:69:00:00:0a

4. Record the IP address information.

Enter ipAddrShow -sw; then, copy the command output into the “config-miscinfo.txt” file on a workstation.
