Maintaining HSI/P cards
An HSI/P card supports X.25 switch links. For eight links, two HSI/P cards and two quad
cables are needed. If the system uses TCP/IP signaling for all links, HSI/P cards are not
needed. HSI/P cards are not supported beginning with CMS R12.

If you are replacing a defective HSI/P card, see Replacing an HSI/P card on page 80. If
this is the initial installation of one or two HSI/P cards, start with Installing the first HSI/P
card or a pair of HSI/P cards on page 85. If a second HSI/P card is being added to a
system already in operation, see Adding a second HSI/P card on page 90.
Replacing an HSI/P card
To replace an HSI/P card:
1. Log in to the system as root.
2. Enter:
cfgadm
This displays the PCI card configuration before you replace a card. Recheck the
configuration after you have replaced the card.
3. Enter:
/usr/sbin/shutdown -y -i0 -g0
This shuts down the system.
4. Press and release the front panel power button to turn off the system.
Wait for the front panel Power/OK LED to turn off.
