The chapter contains the following sections:
Section 9.1, "PCI Cards" on page 9-2
Section 9.2, "Processor Modules" on page 9-4
Section 9.3, "Memory Modules" on page 9-9
Section 9.4, "Replaceable Battery" on page 9-12
Section 9.5, "LOMLite2 Card" on page 9-14

Note – The only hot-swap components in the Netra T4 system are the hard disks.
All other components, including those described in this chapter, require the system
to be powered down and electrically isolated before they can be removed or fitted.
Caution – Use proper ESD grounding techniques when handling components. Wear
an antistatic wrist strap and use an ESD-protected mat. Store ESD-sensitive
components in antistatic bags before placing them on any surface.
Caution – The plug at the end of the AC power cord is the primary means of
disconnection for the Netra T4 AC100 system.
Caution – To isolate the Netra T4 DC100 system, open the circuit breakers on both
negative supply conductors.
