igure 2-3 step 2).
5. Tighten the screws to secure each bracket.
6. Proceed to “

procedure.
Completing the Installation
To complete the installation process, follow these steps:
1. Install any additional hubs into your stack.
2. Install optional cascade cables according to instructions in
“
Connecting the Stack with Cascade Cables” on page 6.
3. Install your management extension cables to any remote cascades
according to instructions in “
Extending Management to Remote
Cascades” on page 9.
4. When all of the hubs, modules, and cables are in place, connect the
power cord(s).
a. For a hub with an AC power source, connect the appropriate power
cord as required by your national electrical codes and ordinances, first
to the hub and then to the power source.
Bay Networks recommends that you connect power to the top hub first
and continue down the stack. The stack requires at least one in every
four hubs to be powered on to function correctly.
b. For a hub with a DC power source, refer to “Connecting to a –48 V DC
Power Source” for the correct installation of the ground wire, terminal
leads, and safety considerations for −48 V DC hubs.
5. Make port connections using the appropriate ports and cables
according to information in Chapter 1, “Quick Reference
Information.”
6. Verify your installation according to instructions in “
Verifying Your
Installation” on page 11.
