Reset Switch The reset switch is located at the lower left corner of the front panel (see Figure 1-3 and Figure 1-4). It is recessed to protect it from being pressed unintentionally. Pressing the reset switch interrupts normal operation, reinitializes the server, begins the startup sequence, and purges server RAM in the same way as toggling the power switch. The Self Test LED lights as the server executes self-test diagnostics. The Boot State LED lights as the server boots from its software diskette or the network.

CS/2600 Internal Model CS/2600 includes a 3.5-inch, 135-tpi diskette drive located on the Diskette Drive right side of the front panel (see Figure 1-4). The drive can

accommodate 1 MB or 2 MB unformatted capacity (720 KB or 1.44 MB formatted) diskettes. This drive is used for booting system software and for performing memory dumps following a server failure. The diskette is also used during operation to maintain software configuration information.
