Installation
Install interface card.
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
Install interface card.
2. Open the front door of the router by pulling its lock—the round post
at the upper right—to the right.
Figure 1. Opening Router Door
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
Installation
Install interface card.
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).

Figure 3. Disengaging Card Bezel
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, s lide the back
of the tray about half-way into the router.
6
Installation
Install interface card.
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°.
Figure 4. Installing Interface Card
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 s trip 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.

Installing the Interface Card (System Online)
Note If you will be installing the new interface card in a slot where another
interface card is not currently installed, skip steps 1 and 3.
1. Disconnect all cables from the interface card you will be removing,
and save them for reconnection when you later install that card again.
2. Connect a grounding wrist strap (one is provided with the interface
card) to your wrist and to the back of the router.
3. If the Swap LED on the interface card you will be removing is not on
(see figure 6), press the adjacent Swap button, and hold it until the
Swap LED turns on (about 1–5 seconds).

until the card fully engages and the locks swing inward to about 45°.
Figure 9. Installing Interface Card
9. Push the two locks evenly to close them, pressing downward slightly
to secure them in place. A self-test of the new interface card begins.
10. When the self-test is complete (after about 5 seconds), check that the
new interface card’s Card LED (the first LED in the row of LEDs in
the router door) has turned green, and the Self-test LED (the second
LED in the row) has turned off.
• If these LEDs continue flashing, the card is not seated properly.
Adjust the position of the card by pushing evenly on both ends,
and adjust the positions of the locks evenly.
• If the Card LED remains orange and the Self-test LED remains on,
the card has failed the self-test. Refer to “Interface Card Self-Test
Failure During Hot Swap” in table 3-2, “LED Error Patterns
During Router Operation.”
• If the Card LED remains orange but the Self-test LED has turned
off, look in the event log (which can be displayed from the Main
menu) for the entry “Slot x HWID and Line configuration
mismatch” (where x is the number of the slot). If that entry
appears in the event log, specify the new card for that slot in the
configuration (refer to “Configure and boot the router” in chapter
1 of the HP Router 650 Installation Guide). If that entry does not
appear in the event log, call for service from your HP dealer or
service provider.

Connect network cables.
Connect the network cables as described below. You should also make
sure that all network equipment and links are ready.
Caution Static discharge may damage equipment. Do not touch the connector
pins on the interface card or on the cable.
1. Secure the D-connector on the token ring cable to the token ring
port, using the screws on the connector.

Installation
Arrange network cables.
Arrange network cables.
To help keep the network cables orderly—and out of the w ay wh en
interface cards are being removed or installed—arrange the cables over
the bars at the right of the router.
These cable-management bars have slots in them that you can use for
tie-wrapping the network cables. Included with each interface card is a
tie-wrap that you can use to wrap the cables and then attach the bundle
to the cable management bar, as shown in figure 13.
Figure 13. Cable-Management Bar and Tie-Wrap
Some cables (such as WAN cables) will not fit inside the cable management bars. You can use the tie-wraps to bundle the extra cables and
hang them on the outside of the bar.

Prepare the router.
Prepare the router.
To prepare the router after installing the new interface card, you should
do the following procedures, all of which are described in chapter 1 of
the HP Router 650 Installation Guide:
Connect a console.
Plug in and verify router hardware.
Configure and boot the ro uter.
Verify router initialization and configuration.
Note If you are installing the interface card in place of a different type of
interface card (for example, if the slot in which you are installing the
interface card formerly held a WAN interface card), or if you are
installing the interface card in a slot that formerly was empty, you must
specify the new card in the configuration.
If any port has no network attached during router operation, event log
messages are generated. To avoid these messages, disable that port
when you configure the router.

Troubleshooting
For general information about troubleshooting problems using any
interface card in the Router 650, refer to chapter 3 of the HP Router 650
Installation Guide. The following troubleshooting information is
specific to the token ring interface card.
Note In the description of the port status LEDs in chapter 2 of the HP Router
650 Installation Guide, the label “Tx” is shown for the third port status
LED for each port. On the LED label strip used with the token ring interface card, however, the third port status LED for each port is labeled
“Ins” instead (“Tx” is used for most other interface cards). The Ins LED
is lit green when the corresponding port on the interface card is passing
the token.
If the Net Fail LED for any (but not all) of the ports on the interface
card is lit during router operation, this may mean one of the following:
The network cable is loose, disconnected, or faulty.
The TCU is faulty.
The ring speed is configured incorrectly.
