Figure 4–4 shows the T2019 power regulator module. It must be inserted
in slot 2 of the XMI cage with slot 1 empty. (The heat sinks on the T2019
protrude into slot 1, as shown in the enlargement in Figure 4–4.)
Follow these steps to install the T2019 module:
1. At the front of the cabinet, insert the T2019 module in slot 2 of the XMI
card cage.
2. Power up the system with only the T2019 module in the XMI card cage.
The four LEDs on the module indicate status, as listed in Table 4–1.
Table 4–1 lists the meaning of the LEDs. The top two lights should be lit to
indicate that the H9657-CX kit has been properly installed and is working.
