Brocade Communications Systems DCX Backbone, Hardware Installation Manual

Page: 125 / 167

For clarity, the two "sets" of cables are drawn differently in Figure 46 through Figure 48 . Also note that one set is
connected to only the blades in the "low order" slots (slot 3 in the DCX-4S and slot 5 in the DCX) and the other set is
connected to the blades in the "high order" slots (slot 5 in the DCX-4S and slot 8 in the DCX). Keeping the sets apart in
this manner minimizes the cable confusion.

2. Recording critical Brocade DCX and SAN information on page 126
3. Disconnecting from network and fabric on page 129
4. Removing components from the chassis on page 130
5. Installing the replacement chassis on page 130
6. Installing components into the new chassis on page 131
7. Verifying correct operation of system on page 132
8. Reconnecting the system to the network and fabric on page 134

The chassis replacement takes approximately 3 hours.
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 140 cm (55 in.) and carries a minimum of 113 kg (250 lb)
• A surface on which to place the old chassis, 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
