HP StorageWorks SAN Director Installation Guide (A7393-90009, May 2007)

Setting up and installing modems182
NOTE: The modems must be powered on and operational before the 4/256 SAN Director is
powered on, to allow the 4/256 SAN Director to detect the modems during boot.
3. Verify that both modems indicate they are ready by illuminating their “Clear to Send” (CS),
“Terminal Ready” (TR), and “Modem Ready” (MR) indicators. If this does not occur, ensure that
the modems are connected to a power source and are powered on, and check all modem cable
connections.
4. Verify that POST is complete on the 4/256 SAN Director (a minimum of 3 minutes).
5. Dial in to the telephone number assigned to the 4/256 SAN Director, using a telco system to
dial-in to the modems or the setup described in ”Setting up a remote modem system” on
page 180.
6. Observe the modem lamps: the Ring indicator should flash briefly as the telephone rings. If the
Ring indicator does not flash on both units, recheck the incoming telephone lines to the modems.
7. Verify that after one ring, the modem associated with the active CP card (usually in slot 5),
illuminates the “Off Hook” (OH) indicator on the modem and a login prompt is presented to the
remote client.
8. Log in to the switch from the remote client as admin. The default password is “password”.
NOTE: If the Off Hook indicator illuminates on the standby CP card modem, recheck the modem
cable connection to the active CP card.
9. Log out of the modem session.
10. Remove the telco connector from the active CP card modem, leaving the telco line from the
standby CP card connected to the “Y” connector (see Figure 39 on page 178).
11. Dial in to the telephone number assigned to the 4/256 SAN Director, as described in ”Setting
up a remote modem system” on page 180.
12. Observe the modem lamps: the Ring indicator should flash only on the modem connected to the
standby CP card.
13. Verify that after seven rings, the Off Hook indicator on the standby CP card modem is
illuminated. A login prompt is presented to the remote client, and a message confirms that the
standby CP card is being logged in to. You can log in or disconnect the session, as desired.
14. Reconnect the telco connector to the active CP card modem.
The 4/256 SAN Director modems are ready for use.
