Chapter 6 Removing and Replacing Hot-Swappable Boards 6-15
15. Carefully slide the board out of the slot and place it on an electrostatic discharge
mat.
If you enter the
cfgadm
command after you remove the alarm card, you see
disconnected
under the Receptacle column. For all other boards, after you remove
the board, you see
empty
under the Receptacle column.
16. Perform any necessary board-specific hardware procedures.
For example, you might want to remove the PCI mezzanine card (PMC) from a
faulty satellite CPU or I/O board, and install it on the replacement board. Refer to
the documentation that you received with your board for more information.
17. If necessary, secure a blank filler panel over any empty I/O slots.
If you are not going to replace the board right away, you must install a blank filler
panel over the opening to ensure proper airflow in the system. The slot filler panel is
secured to the board cage using two screws, one at the top of the filler panel, the
other at the bottom.
18. Remove the rear transition module.
For instructions, see Section 6.2, “Rear Transition Modules” on page 6-24 .
6.1.2.2 Inserting a Board
Caution – When inserting multiple boards in different slots of the system, insert the
boards one at a time and wait until each board is fully configured in the system. If
you insert multiple boards at the same time, you might panic or hang the system.
Note – If you are installing a Netra CP2140 host CPU board into a Netra CT server,
do not change the default SMC module switch settings on the SW0501 switches. The
Netra CT server supports high availability hot-swap; however, because the alarm
card controls the high availability on the Netra CT server, the settings on the
SW0501 switches on the Netra CP2140 host CPU board should be set in the
default,
non-high availability settings. Refer to the Netra CT Server Product Overview for more
information.
1. Attach the antistatic wrist strap.
See Section 1.2, “Attaching the Antistatic Wrist Strap” on page 1-2 .
2. Locate the board slot where you are installing the board.
