Lenovo TD100X manual To install a DIMM, complete the following steps

Attention: Static electricity that is released to internal server components when the server is powered-on might cause the server to stop, which could result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when working inside the server with the power on.

To install a DIMM, complete the following steps:

1.Read the safety information that begins on page vii and “Safety statements” on page x.

2.Turn off the server and peripheral devices, and disconnect the power cords and all external cables.

3.Remove the side cover (see “Removing the side cover” on page 78).

4.Rotate the power-supply cage assembly out of the chassis: v Hot-swap models:

a.Remove the hot-swap power-supply. Press down on the orange release lever and pull the power supply out of the bay, using the handle.

b.Lift up the power-supply cage handle and pull the power-supply cage assembly all the way up until the retainer latch locks the cage in place on the chassis.

vNon-hot-swap models, lift up the power-supply cage handle and pull the power-supply cage assembly all the way up until the retainer latch locks the cage in place on the chassis.

5.Locate the DIMM connectors on the system board. Determine the connector in which you will install the DIMMs. Install the DIMMs in the sequence indicated in Table 15 on page 99 and Table 16 on page 100

Note: DIMM connectors 3, 6, 9, and 12 are not functional in ThinkServer TD100 models. Do not install DIMMs in these connectors.

Attention: To avoid breaking the retaining clips or damaging the DIMM connectors, open and close the clips gently.

6.Open the retaining clips 2 and, if necessary, remove any existing DIMM 1.

7.Touch the static-protective package that contains the DIMM to any unpainted metal surface on the server. Then, remove the new DIMM from the package.

8.Turn the DIMM so that the DIMM keys align correctly with the slot.
