Use the information in the following section to service the A/B Switch.
The A/B Switch is a card cage filled with switching cards. A special cable is required to join together all of the switching cards. Cisco uses an EIA/TIA-232 lead-sensing A/B Switch as the primary switch and the RJ-45 and V.35 switches as secondary. The cards are hot-swappable.
The A/B Switch comes in a DC and AC version. Both versions have redundant power supplies. The card cage has twelve card slots for gang switching and the master control card (MCC). The card slots are numbered from right to left when viewing the A/B Switch from the rear. The MCC has to be located in slot 1. The gang switches go in slots 2 through 12. All or none of these slots can be filled with switch cards. Each slot must have either a switch card or a filler plate installed in order to meet EMC requirements. A gang cable connects the MCC to the switching cards located in slots 2 through 12.
Each switching card has a three-position manual control switch that is accessible from the front of the rack-mount enclosure. For the failover functionality to work, the manual control switches must be in the AUTO position.
The AC-powered A/B Switch is equipped with replaceable fuses on its power supply. The fuse is located on the rear panel at reference designator F1 (see Figure 6-9). Two spare 250V 3A fuses (3A Slo-Blo, 3AG Type, Littlefuse part number 313003) are included with the A/B Switch documentation that shipped with your system.
Use the following steps to replace the fuse on the A/B Switch power supply card:
Step 2 Locate the fuse at the location marked 3A 250V.
 |
Warning The A/B Switch fuses may be hot to touch: be careful when removing the unit. |
Step 3 Remove the fuse from the power supply card.
Step 4 Install the replacement fuse (3A Slo-Blo, 3AG Type, Littlefuse part number 313003).
|
Warning The DC powered A/B Switch relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 3A is used. |
The A/B Switch is equipped with replaceable fuses on its power supply cards. Two spare 250V 2A fuses (Littlefuse # 312.002) are included with the A/B Switch documentation that shipped with your system. The fuse is located at reference designator F1, as shown in Figure 6-10.
Use the following instructions to replace the fuse on the A/B Switch power supply card:
Step 2 Remove the two mounting screws from the faceplate of the power supply card.
Step 3 Slide the power supply card out of the A/B Switch card nest.
Step 4 Locate the fuse at location F1 (see Figure 6-10).
Step 5 Remove the fuse from the power supply card.
Step 6 Install the replacement fuse (2 amp, 250V, Littlefuse # 312.002) in location F1.
Step 7 Reinsert the power supply card in the A/B Switch card nest.
Step 8 Insert and tighten the two mounting screws on the power supply card faceplate.

Tips For additional A/B Switch documentation, see "Related Documentation" section. |
The ARU (Dataprobe SB-4 stunt box) is an option for the TC-E450-AC series Cisco MGC. The ARU supports physical office alarming functions required by many telephone companies. This section describes how to program the ARU and describes the ARU battery and fuse replacement. Figure 6-11 and Figure 6-12 show the ARU.
The following sections describe how to program the Dataprobe SB-4 to act as a Cisco ARU.
Follow these steps to log in to the ARU and obtain the main menu.
 |
Note You will need additional asynchronous ports and cables for programming in addition to the standard configuration cables. See the "Connecting the ARU and Serial Port Expander" section. |
aru:dv=devname:br#9600:el=^C^S^Q^U^D:ie%$:oe=^D: aru_init:dv=devname:br#2400:el=^C^S^Q^U^D:ie%$:oe=^D:
Replace the bold characters above with the full path name to the ARU command port name (for example: /dev/term/a). This will allow you to use the command tip aru to access the command port of the ARU under normal conditions and to use the command tip aru_init to access the command port on an unmodified SB-4. The ARU (SB-4) has a menu-driven programming interface.
Step 2 Log into the ARU by entering tip aru (for an existing ARU) or tip aru_init (for a new ARU). You will see confirmation of the connection. (You can leave TIP by entering
< ~ . > at any time.)
The ARU is connected to the Cisco MGC host computer through an asynchronous connection. To talk to the ARU, the UNIX utility TIP is required. When the unit is new, the command port is set at 2400 baud.
Change the command port to 9600 baud to use the tip aru command as follows:
a. Press Enter.
b. Enter the following:
<security code>
c. Press Enter.
LOCATION: ARU1 STUNT BOX 4 ENTER SECURITY CODE > TEST LOCATION: ARU1 STUNT BOX 4 S) ALARM STATUS R) RELAY CONTROL P) PROGRAMMING X) EXIT / DISCONNECT ** NEW EVENT ** VIEW STATUS SCREEN > p
Program the baud rate of the command and monitor ports, create a password, and find the location ID and time as follows:
The main programming menu is displayed.
Step 2 Check the baud rates of the command and monitor ports:
a. Enter A to check the monitor port setup.
b. Enter B to check the command port setup.
If the baud rate is not 9600, do the following:
c. Press Enter to return to the main programming menu.
Step 3 Exit and log back in to the ARU. This causes the higher baud rate to take effect. To do this, enter the following commands:
a. Enter M and press Enter to return to the main menu.
b. Enter X and press Enter to log off.
c. Use < ~ . > to return to the UNIX prompt.
d. Enter tip aru to reconnect to the ARU.
e. Press Enter to return to the login screen:
