Install interface card.
Notes You can install the interface card without taking the system offline (that
is, without switching the router off and taking all networks down)—
refer to “Installing the Interface Card (System Online),” page 9.
(Installing an interface card without taking the system offline is often
called “hot swapping.”)
If you are installing the interface card in a slot that formerly was empty,
or if you are installing the interface card in a slot that formerly held a
different type of interface card (such as a WAN interface card), you must
specify the new card in the configuration. (Refer to “Configure and boot
the router” in chapter 1 of the HP Router 650 Installation Guide.)
Installing the Interface Card (System Offline)
Note If you will be installing the new interface card in a slot where another
interface card is not currently installed, begin with step 2; otherwise,
begin with step 1.
1. Disconnect all cables from the interface card you will be removing,
and save them for reconnection when you later install that card again.
Installation

2. Open the front door of the router by pulling its lock—the round post
at the upper right—to the right.
3. Switch the power supply off by pressing the bottom of its switch
(marked with “❍”). If two power supplies are installed, switch both
off.
4. Connect a grounding wrist strap (one is provided with the interface
card) to your wrist and to the back of the router.

5. Press down slightly on the insides of both locks on the old card’s
bezel (see figure 2), then swing them outward until the bezel
disengages (see figure 3).
6. Grasping the left and right edges of the bezel, pull out until the tray is
about half exposed.
7. Grasping the sides of the tray, remove the card from the router.
8. Holding the new interface card by the sides of its tray, slide the back
of the tray about half-way into the router.

9. Pull the locks on the bezel outward, then push evenly on both ends
until the card engages fully and the locks swing inward to about 45°.
10. Push the two locks evenly to close them, pressing downward slightly
to secure them in place.
11. Remove the old card’s LED label strip in the router door from the
position corresponding to the slot where you have installed the
interface card, then insert the LED label strip provided with the new
card as far as it will go.
12. Bend the end of the label strip toward the back of the router,
creating a 90° fold.
13. Switch on the power supply by pressing the top of the switch
(marked with “|”).
14. Close the router door.

ment or site served by the interface card, slide it out from the right.
Position the new label with its shiny side facing the router, and slide
it in from the right. (Additional labels are provided in the router’s
accessories kit and also with each interface card.)
