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.

ATTENTION
Use safe lifting practices when moving the product. (C015)
A fully populated PowerConnect B-DCX-4S (four FC8-48 port cards, 192 ports) weighs approximately 68 kg (150 lbs) and requires a hydraulic or assisted lift to install it.
If the PowerConnect B-DCX-4S is installed in a cabinet, ensure that the cabinet is balanced and secured mechanically and that the removal and installation procedure will not compromise cabinet stability.
1. If the chassis is in a cabinet, remove it from the cabinet, remove the rack mount hardware, and save the
hardware for use with the new chassis.
2. Place the chassis on a lift or on the shipping pallet provided with the original chassis.
3. Unpack the new chassis:
a. Cut the bands that encircle the packaging.
b. Remove the lid and the kits and foam from the top of the chassis.
c. Lift the cardboard box off the chassis and remove the plastic bag from around the chassis.
Save the packing materials for use when returning the old chassis.
d. Leave the chassis on top of the plastic shipping tray if the chassis must be transported to the installation
location.
The PowerConnect B-DCX-4S packaging does not incorporate wood pallet and pallet brackets. The chassis sits on top of plastic shipping tray.
4. Use a pallet jack or other assisted lift to transport the new chassis to the installation area. Doorways must be
wider than 91 cm (36 in.) to accommodate the chassis on the pallet.
5. Use a lift to raise the chassis to the correct level. If installing the chassis in a cabinet, follow the instructions
provided by the rack kit manufacturer.

tools, such as Telnet or Web Tools. Ensure that the PowerConnect B-DCX-4S is not modified using other connections during the rest of this procedure.
2. Reconnect the transceivers and cables to the port blades:
The ports and cables used in trunking groups must meet specific requirements. For a list of these requirements, refer to the Fabric OS Administrator’s Guide.
a. Position one of the transceivers so that the key is oriented correctly to the port and insert the transceiver
into the port until it is firmly seated and the latching mechanism clicks.
b. Select the cable that corresponds to the port and position it so that the key (the ridge on one side of the
cable connector) is aligned with the slot in the transceiver; then, insert the cable into the transceiver until the latching mechanism clicks.
c. Repeat step a and step b for the remaining ports.
Do not route cables in front of the air exhaust vent (located on the upper port side of the chassis and possibly the lower side if using the port side exhaust kit).
d. Organize the cables as required.

Verifying correct configuration of the fabric

Copying the command outputs from this section into a file is recommended.
1. Create an “after” SAN profile by entering the following commands and copying the output to a text file named “SANafter.txt”:
• nsShow
• nsAllShow
• switchShow
• fabricShow
switch:admin> nsshow Type Pid COS PortName NodeName TTL(sec) N 020f00; 3;10:00:00:01:73:00:29:46;10:00:00:01:73:00:29:46; na Fabric Port Name: 20:0f:00:60:69:90:03:f0 <output truncated>

Page 13
switch:admin>
2. Determine any differences between the information in the “SANafter.txt” file and the information in the
“SANbefor.txt” file created earlier. In particular, look for differences in the following:
• Device types
• Number of devices
• ISL and port states
• Number of switches in the fabric
3. Resolve any issues or unintentional changes to the PowerConnect B-DCX-4S or fabric.
• If there are any mechanical problems, try reseating the associated component.
• If the configuration information is not correct for the PowerConnect B-DCX-4S, modify as required. If
necessary, the configuration saved before the replacement can be downloaded using the configDownload command.
The configDownload command can be entered through a Telnet or serial session, but the PowerConnect B-DCX-4S must have an Ethernet connection to the server name or IP of the host for the download process to complete. For more information, refer to the help configdownload command or the Fabric OS Command Reference.
switch:admin> configdownload Server Name or IP Address [host]: 123.123.123.123 User Name [None]: Admin24 File Name [config.txt]: config-switch.txt Password: xxxxxxxx download complete switch:admin>

Powering on the PowerConnect B-DX-4S

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 PowerConnect B-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. For information about LED patterns, see the PowerConnect B-DCX-4S Backbone Hardware Reference Manual.
You can bypass POST by using the fastBoot command. You can also disable POST for successive reboots on the PowerConnect B-DCX-4S using the diagDisablePost command.
Do not connect the switch to the network until the IP addresses are configured.
