Maintaining the WANJet 500 Platform
Reviewing maintenance options
The WANJet 500 platform contains several field replaceable units (FRUs). The FRUs provide the ability to replace parts of the system without replacing the complete system. The FRUs currently available for this platform are:
- Power supply replacement
- Hard drive replacement
Changing a power supply
The WANJet 500 platform has two hot swappable redundant power supplies. You can replace the power supply in the event of a power supply failure.
Replacing the power supply
You do not need special tools to replace a power supply. Because the power supply is a redundant, hot swappable power supply, you can replace it while the system is running.
To replace a power supply
- On the back panel of the device, locate the power supply that you want to replace.
- Remove the power cable from the power supply that you want to replace.
A power supply alarm sounds, indicating that a power supply was removed or is not receiving power.
- To silence the alarm, press the alarm mute switch (number 3 in Figure 1.4 ) that is located to the left of the power supply array.
- Each power supply is secured to the chassis by a self-clinching knurled fastener and release lever. Loosen the knurled fastener by turning it counterclockwise.
- Move the release lever to the left and pull the power supply out of the system.
- Slide the new power supply into the power supply slot.
The power supply is connected to the system when you slide it completely into the chassis.
- Tighten the knurled fastener into place by turning it clockwise.
- Re-attach the power cable.

Replacing a hard drive
The WANJet 500 platform includes one hot swappable hard drive and has a slot for an optional second hot swappable hard drive. You can change or replace a hard drive tray as part of the routine maintenance of the unit, or in the event of a drive failure.
Removing and replacing a hard drive tray
You do not need special tools to replace a hard drive tray.
To remove a hard drive
- Each hard drive tray is secured by a simple switch. To unlock the switch, turn the switch counterclockwise from Lock to Open.
- Push the Lock/Open switch slightly to the left to release the tray lever.
The tray lever extends from the drive tray.
- Grip the tray lever and pull the drive tray out of the system.
