Troubleshooting the Boot Process on EX4500 Switches

Problem

Description:

For EX4500 switches running Junos OS 10.4R2 or later, the switch halts

during the boot-up process.

Cause

The Intraconnect module or the Virtual Chassis module is not installed in the switch.

Solution

Disconnect power from the switch by performing one of the following tasks:

•

For each installed AC power supply:

•

If the AC power source outlet has a power switch, set it to the OFF (0) position.

•

If the AC power source outlet does not have a power switch, gently pull out the
male end of the power cord connected to the power source outlet.

•

For each installed DC power supply:

•

Open the input circuit breaker so that the cable leads will not become active while
you are installing the Intraconnect module or the Virtual Chassis module.

Install either the Intraconnect module or the Virtual Chassis module in the switch. See

“Installing an Intraconnect Module in an EX4500 Switch” on page 129

“Installing a

Virtual Chassis Module in an EX4500 Switch” on page 131

Connect power to the switch by performing one of the following tasks:

•

For each installed AC power supply:

•

If the AC power source outlet has a power switch, set it to the ON (I) position.

•

If the AC power source outlet does not have a power switch, plug in the male end
of the power cord connected to the power source outlet.

•

For each installed DC power supply:

•

Close the input circuit breaker so that the cables are active again.

Verify that a working Intraconnect module or Virtual Chassis module is installed in
the switch using the CLI command

show chassis hardware

. You should see either the
