System Platforms
The CSX5500 is a rack-mountable platform. The front panel has an air-intake grill, an auxiliary
keyboard jack, and a peripheral access door, which may be latched. The activity indicators for
power-on and disk activity, diskette drive, and control buttons are located behind the access door.
The back of the chassis has mountings for a RS-232 serial port, and connectors for a keyboard and
monitor. The chassis has eight ISA slots for LAN and WAN adapters. However, because of power
and cooling restrictions, we limit the number of usable adapter slots to five (one for a LAN adapter,
and up to four for WAN adapters).

The CSX5500 has a removable air filter. This filter is provided to ensure system cleanliness and
stability in dusty operating environments. The filter is located just behind the left side of the
chassis’ front panel. For best performance (and as an alternative to replacement) regularly wash the
filter in warm water and a mild detergent.
Before removing the air filter for cleaning, read the following warning and caution notes.
WARNING
Before removing the air filter for cleaning, ensure that the system is powered off and the power
cord is unplugged from the power source. Note that the Power ON/OFF switch does not
disconnect the power from the system. Failure to unplug the power cord can result in serious
injury or equipment damage.
CAUTION
An electrostatic discharge (ESD) can damage your system. We recommend that you perform
this procedure only at an ESD workstation. If such a workstation is unavailable, provide some
ESD protection by wearing an antistatic wrist strap attached to chassis ground when handling
components.
