Caution – The Non-Volatile Random Access Memory/Time Of Day
(NVRAM/TOD) clock module contains the system host identification (ID) and
Ethernet address.
It is made of electronic components that are extremely sensitive to static
electricity. Always wear a grounding strap when you handle the
NVRAM/TOD module. Handle the carrier only by the edges. Do not touch the
components or any metal parts.
1. Locate the NVRAM/TOD module on the system board (Figure 2-6).
Look for a sizeable chip with a stick-on label.
