2. Enable the FORCED PROM mode on the switch.
Using FORCED PROM mode allows the switch to use firmware stored in PROM,
rather than flash memory, while you configure the switch IP address. You can use
either the Force PROM button (16-port switch) or the Test Mode switch (8-port
switch).
▼ To Use the Force PROM Button for the 16-port switch.
The button is on the back panel of the switch chassis below port 16.
a. Isolate the switch chassis from the fabric and power the switch off.
b. Press and hold the Force PROM button, and power the switch on.
c. Allow the switch to complete the POST, and release the Force PROM button
(this should take 5-10 seconds).
d. Observe the heartbeat LED for error codes (5 blinks is normal when in Force
PROM mode).
Correct the conditions or reconfigure the switch as required.
▼ To Use the Test Mode Switch for the 8-port Switch
The test mode switch is a small rotary switch on the back of the switch chassis. The
test mode switch position determines which operating mode the switch enters when
the switch chassis is powered on. Normal operation is indicated by the alignment of
the small notch on the test mode switch with the dot on the faceplate.
a. Using a small screwdriver, rotate the test mode switch four clicks clockwise to
the Force PROM position.
b. Turn the power switch off for three seconds, and then back on to reset the
switch chassis.
c. Observe the heartbeat LED for error codes (5 blinks is normal when in Force
PROM mode).
d. If you do not observe the blink code, re-align the small notch on the test mode
switch with the dot on the faceplate and return to Step a.
e. Rotate the test mode switch four clicks counter-clockwise to the normal
operating position.
