Removal and
Replacement
Caution
This section explains removal and replacement of the HP 27115A
HP-FL PCA.
Typically, you will use this information if you suspect the
PCA
is faulty and need
to replace it, or when you wish to modify the I/O slot configuration.
Switch off the power to both the computer system and the associated peripheral
device before attempting to remove any
PCA
or cable from the system.
The
HP-FL PCA
is susceptible to damage by electrostatic discharge. When
handling, removing, or installing the card, use a grounding wrist strap. Handle
the card only by its edges or extractor levers. See the "Safety Considerations"
section in the front of your system manual for additional information. If you do
not have a static-free area available, use work station kit (9300-1155) to protect
the
HP-FL PCA
from damage.
PCA Removal
To remove the
PCA:
4-2 Replaceable Parts
1. At the host computer, shut the operating system down and switch off
the computer system power. Refer to the system administrator's and
hardware manuals that apply to your system.
2. Open the
CIO
card cage where your HP 27115A
HP-FL PCA
is installed
(refer to your computer or extender hardware's manuals).
Simultaneously lift both extractor levers to pull the
PCA
from the
CIO
bus connector. After the
PCA
is unseated, grasp it by the levers and
slowly guide the card partially out, about 10 cm (2 in.).
3. Disconnect the
HP-FL
cable from the HP 27115A
PCA'S
optical ports
and the grounding bus. Then remove the
PCA
completely from its slot.
4. Lay the
PCA
on a grounded surface to protect
PCA
components from
electrostatic discharge. (If you are not wearing a grounding wrist strap,
you will damage the
HP-FL PCA.
Always use anti-ESD precautions.)
