The VIPRION® 4800 Series platform contains several components that you can replace individually without exchanging the entire system. This platform contains these replaceable components:
The VIPRION® 4800 platform supports up to four hot swappable power supplies.
The platform supports power redundancy, which ensures that the system is unaffected if a single power supply fails in a system containing more than one power supply. In the event of a power supply failure, you can replace a failed DC power supply without powering down the system. For maintenance, you can replace a working power supply, provided that there are working redundant supplies installed in the system. There must be two or more working power supplies if 1-3 blades are installed. There must be three or more working power supplies if 4-8 blades are installed. The system can operate without redundancy at max capacity with two of the four power supplies installed.

The DC power supply does not have an on/off switch. You can control the power from the rack switch or the DC power source.

The VIPRION® 4800 Series platform has a removable fan tray that is designed to maintain airflow throughout the chassis. You can change or replace the fan tray as part of the routine maintenance of the unit, or in the event of a fan failure. The fans in the fan tray run constantly while the unit is on. Over time, the fans can wear out, requiring you to replace the fan tray.

By default, VIPRION® B4000 blades contain one storage drive. You can remove the drive from the blade only if your company's security requirements necessitate it when performing a Return Material Authorization (RMA) on the platform.
The top bezel on the front of the VIPRION® 4800 chassis includes an LCD component that enables you to access several functions associated with the platform, such as configuring the management port for the system.
The VIPRION® 4800 platform includes replaceable chassis and power supply filters. You must remove the bottom bezel to access these filters. The chassis filter is located above the power supplies and below the blade slots. The power supply filter is located on the bottom bezel.
The VIPRION® 4800 platform includes two annunciator cards. You can change or replace the cards in the event of a failure.
