Replacing A Module; Replacing An Interface Card (System Online) - HP 650 Installation Manual

N o t e s

Replacing a Module

You can replace any interface card or the cooling module without taking
the system offline (that is, without switching the router off and taking all
networks down). If you have installed a second power supply, you can
also replace either power supply without taking the system offline.
(Replacing a module without taking the system offline is often called
"hot swapping.")
To replace the routing engine or the PCMCIA flash card, or to replace
the power supply if a second power supply has not been installed, you
must take the system offline; refer to "Replacing a Module (System
Offline)," page 3-27.

Replacing an Interface Card (System Online)

If you are replacing an interface card with a different type of interface
card (for example, if you are replacing an Ethernet/802.3 card with a
token ring card), or if you are installing a card in a slot that formerly was
empty, you must specify in the configuration the new card for that slot
after the card has been installed. (Refer to "Configure and boot the
router," page 1-21.)
The following procedure is applicable to any of the interface cards. For
replacement procedures specific to a particular interface card, refer to
the documentation provided with it.
1. Disconnect all cables from the interface card, and save them for
reconnection after the new card is installed.
2. Connect a grounding wrist strap to your wrist and to the back of the
router.
3. If the Swap LED is not on (see figure 3-5), press the Swap button,
and hold it until the Swap LED turns on (about 1–5 seconds).
