Chapter 9: Installing Switch Components 8. Tighten the screws, one on each side of the SRE module, by turning them clockwise using the Phillips (+) screwdriver, number 2. Ensure that the SRE module is fully seated in the chassis. It must be fully seated in order for it to be powered up. 9. Verify that the SRE module is installed correctly and functioning normally by checking the LEDs on the faceplate of the SRE module. The ON LED and ST LED should be lit steady green a few minutes after the SRE module is installed. If the ON LED is unlit, verify that there are enough power supplies installed. See "Calculating Power Requirements for a J-EX8208 Switch" on page 79. If more power supplies are needed, install additional power supplies. See "Installing an AC Power Supply in a J-EX8200 Switch" on page 114. If there are enough power supplies in the switch, remove and install the SRE module again. See "Removing an SRE Module from a J-EX8208 Switch" on page 167. If the ST LED is lit steady yellow, the SRE module has failed. Remove the module and install a new SRE module. See "Removing an SRE Module from a J-EX8208 Switch" on page 167.
