Installation and Initial Setup
Power on
After the power switch is turned on, the LED indicators should respond as follows:
• All LED indicators will momentarily blink, which represents a reset of the system.
• The board status LED indicator will blink while the switch loads onboard software and
performs a self-test. After approximately 20 seconds, the LED will light again to indicate the
switch is in a ready state.
• The hot-swap LED indicator will be off.
• The port LED indicators will be off if there is no Ethernet connection and on if there is an
Ethernet connection.
Uninstalling the Board
These instructions explain the mechanical aspects of removing a ZT8101 board from a system.
1. You do not need to turn off the system power to remove a ZT8101 board.
2. Disconnect connections at the faceplate (Ethernet and serial ports).
3. The board should be in a “safe” state to be removed or data may be lost. Signal the system that
a board is about to be removed by partially unlatching the ejectors on the board to be removed.
Do not fully open the ejectors, as this levers the board out of the enclosure and prematurely
breaks its backplane connection.
4. Wait for the blue hot swap LED on the board's faceplate to light; this indicates that board
processes have finished and the board is safe to extract. If the hot swap LED fails to light after
30 seconds, re-latch the ejectors and unlatch them again. In this case, the board is safe to
extract (though the hot swap LED may not light).
5. Once the hot swap LED lights, open the injector/ejector mechanisms fully, rotating the handles
outward until the board disengages from the backplane (refer to “Injector/Ejector Operations”
on page 13).
6. Slide the board evenly out of the enclosure.
7. Install a replacement board or cover the empty slot with a filler panel to maintain the
enclosure's shielding and cooling performance.
