Server User Manual

Back Panel 1-7
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
Diskette Drive
Model
CS/2600 includes a 3.5-inch, 135-tpi diskette drive located on the
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.
Back Panel
The CS/2500 and CS/2600 back panel, shown in Figure 1-5, contains the
power supply module and three types of connectors:
■
