Removing a fan-tray assembly with installed cables
If the fan fails on the fan-tray assembly, replace the entire assembly. You cannot replace an individual
fan. The FAN STATUS LED turns red when one or more fans fail. For a procedure that replaces the fan
tray, see the
“Install the Fan-Tray Assembly” section on page 1-8
1.5 Power and Ground Installation
This section describes how to connect the ONS 15327 shelf assembly to the power supply. Terminate the
chassis ground to either the office ground or rack ground before you install the power. Use the grounding
lug to attach the ground cable to the shelf assembly according to local site practice.
Warning
This equipment must be grounded.
Warning
When installing the node, you must connect the ground first and disconnect it last.
You only ground one cable to ground the shelf assembly. Terminate the other end of the rack ground
cable to ground according to local site practice.
If the system loses power or both XTC cards are reset, you must reset the ONS 15327 clock unless the
node has been previously provisioned to use Simple Network Time Protocol (SNTP) to update the clock
over the LAN.
Warning
Do not apply power to the ONS 15327 until you complete all installation steps.
Warning
Before performing any of the following procedures, ensure that the power is removed from the DC
circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the
DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit
breaker in the OFF position.
