Hardware replacement
CAUTION:
Wear an ESD wrist strap or ESD gloves for hardware maintenance. They are not provided with the
firewall. Prepare them yourself.
Replacing a power supply
CAUTION:
Before you replace a power supply, turn off the circuit breaker and then remove the power cord.
This section applies only to F1000-AI-25, F1000-AI-35, F1000-AI-55, F1000-AI-65 and F1000-AI-75
firewalls that support removable power supplies. The replacement procedure is the same for an AC
power supply and a DC power supply. This section takes a DC power supply as an example.
To replace a power supply:
1.
Face the rear panel of the firewall.
2.
Use a Phillips screwdriver to loosen the captive screws of the power supply.
3.
Hold the power supply with one hand and pull the power supply part way out of the slot.
4.
Supporting the bottom of the power supply with the other hand, gently pull the power supply out
of the slot along the slide rails.
Figure4-1 Removing a power supply
5.
Put the removed power supply on a workbench or into an antistatic bag.
6.
Install a new power supply. If you do not install a new power supply in the slot, install a filler
panel. For the installation procedure, see "
."
Replacing an interface module
CAUTION:
•
Interface modules are not hot swappable. Power off the firewall before you replace an interface
module.
•
For smooth interface module installation in the two interface module slots, use slot 2 prior to slot
1 as a best practice. If you are to install an interface module in slot 2 after an interface module
has been installed in slot 1, you must press down the ejector levers of the interface module
before inserting it into slot 2.
