Isolating A Failed Sun Fireplane Interconnect; Setting Up The System Prior To Replacing The Sun Fireplane Interconnect - Sun Microsystems Sun Fire E25K Service Manual

13.1 Isolating a Failed Sun Fireplane
Interconnect
Caution – The Sun Fireplane interconnect assembly is NOT a hot-swappable
component. This procedure requires powering off the AC power to the system.
1. Check for any error messages during POST.
2. On the SC, check for any error messages in
/var/opt/SUNWSMS/adm/platform/messages.
3. If available, examine any DStop or RStop files located in
/var/opt/SUNWSMS/adm/domain_id/dump.
where domain_id is the domain letter.
13.2 Setting Up the System Prior to Replacing
the Sun Fireplane Interconnect
1. Locate all required tools; two Phillips screwdrivers (No. 1 and No. 2), one small
flat-bladed screwdriver, and one small flashlight.
2. Secure or remove all loose clothing, jewelry, and watches that might get caught on
internal mechanical components.
3. Verify that all I/O cables are properly labeled.
4. Set up an ESD-protected surface for all control expander board sets and system
expander board sets.
5. Attach a wrist strap.
Note – System Control boards, System Control peripheral boards, system expander
boards, I/O boards, CPU boards, centerplane support boards, and the Sun Fireplane
interconnect assembly are all very susceptible to static. Therefore, all possible
precautions should be taken to protect these boards against static damage. Transport
board assemblies on an ESD static-protected cart whenever possible. Use a static
wrist strap when handling.
