One Cisco Dial Access Switching Shelf and Dial-Up Frame Relay Installation and Operation publication for Release 1.4

---

Note Tape 1, DAS (INS) Frame Relay/PPP, and Tape 2, DAS (INS) DIAL-UP FR STATION, have been preinstalled on the DAS Server Shelf at the factory. Tape 3, DAS (INS) DIAL-UP FR DAEMON, must be installed on the StrataView Plus Workstation (see the chapter, Loading DAS Daemon Software on the StrataView Plus Workstation, for the procedure).

Examine the DAS Server Shelf

This section provides descriptions of the front and rear panels of the four DAS Server Shelf models:

• DAS-AC

• DAS-DC

• DAS-AC-E

• DAS-DC-E

The external physical differences in the DAS Server Shelf models are pointed out in this section.

DAS-AC or DAS-DC Front Panel

The DAS-AC or DAS-DC front panel displays the Cisco logo and the product name. There are no functional components on the front of DAS-AC or DAS-DC models, as shown in Figure 3-2.

Figure 3-2: DAS Server Shelf

DAS-AC-E or DAS-DC-E Front Panel

The DAS-AC-E or DAS-DC-E front panel, illustrated in Figure 3-3, displays the Cisco logo, the product name and the following two indicators:

• Power-On indicator indicates that the power is on.

• Status indicator is a tri-colored LED that indicates system status. The status indications are:

  • Off-DAS is off.

  • Blinking red-Unit booting, unit shutting down, factory installed soft-switch cable missing.

  • Red-Unit temperature to high.

  • Green--Unit powered on and ready.

  • Yellow-Reserved for future use.

These status indications apply to both the front- and rear-panel Status LEDs.

DAS-AC and DAS-DC Rear Panel

All physical connections are made to the DAS Server Shelf's rear panel. The DAS-AC and DAS-DC have different rear panels.

DAS-AC Rear Panel

The DAS-AC contains the components and connectors shown in Figure 3-4. The Power On/Off Switch is to the left of the AC-Power Input connector. Later models of the AC-powered DAS Server Shelf come with an AC-power cord clamp. This clamp secures to the bottom edge of the DAS Server Shelf with a set screw, which can be loosened to slide the clamp over the AC-power cord.

Note Unlabeled connectors are not used in DAS Server Shelf and Dial-Up Frame Relay applications.

---

DAS-DC Rear Panel

The DC-Powered DAS Server Shelf contains the components and connectors shown in Figure 3-5. As shown, the DC-powered DAS Server Shelf has inputs for two DC power inputs (DC Input A and DC Input B). Typically these DC inputs are from separate DC power sources to provide protection against a DC power source failure. Each DC Input has its own On/Off Switch.

DAS-AC-E and DAS-DC-E Rear Panels

This section contains descriptions of the DAS-AC-E and DAS-DC-E rear panels.

DAS-AC-E Rear Panel

The DAS-AC-E contains the components and connectors shown in Figure 3-6. The Power On/Off Switch is to the left of the AC-Power Input connector.

Figure 3-6: DAS-AC-E Rear Panel

The DAS-AC-E has the following connectors and switches:

• AC Power Switch,
  
  , providing both graceful and emergency shutdown capability

• AC Power Connector (Single IEC 20)

• Power-On LED lights green when there is power to the unit

• Status LED providing the same indications as the front-panel Status LED

• Frame Relay Card (RS449) connector

• Ethernet Port RJ-45 Connector (referred to as a 10BaseT connector)

• Two Serial Port DB25 Connectors (for attaching a local terminal)

---

Note The factory-installed cable shown in Figure 3-6 is known as the soft-switch cable. It is installed from one of the DB25 connectors to a DB15 connector next to the AC power switch. If it is not installed, the Status LEDs will blink red.

DAS-DC-E Rear Panel

The DAS-DC-E rear panel contains the components and connectors shown in Figure 3-7. As shown, the DAS-DC-E has inputs for two DC power inputs (DC Input A and DC Input B). Typically these DC inputs are from separate DC power sources to provide protection against a DC power source failure. Each DC input has its own circuit breaker.

Figure 3-7: DAS-DC-E Rear Panel

The DAS-DC-E has the following connectors and switches:

• DC Power Switch,
  
  ,providing both graceful and emergency shutdown capability

• Two DC Power Connectors (Euro-style plugable terminal connector receptacles)
  (Phoenix P/N DFK-MSTB 2,5/3-GF-5.08)

• Power-On LED lights green when there is power to the unit

• Status LED providing the same indications as the front-panel Status LED

• Two circuit breakers:

  • Breaker A GOOD green LED is on when circuit breaker A is not tripped, off when circuit breaker is tripped

  • Breaker B GOOD green LED is on when circuit breaker B is not tripped, off when circuit breaker is tripped

• Frame Relay Card (RS449) connector

• Ethernet Port RJ-45 Connector (referred to as a 10BaseT connector)

• Two Serial Port DB25 Connectors (for attaching a local terminal)

Observe Safety Measures

To ensure safe performance as well as to maintain the integrity of your DAS Server Shelf, please observe a few safety measures as you proceed with this installation.

• Do not modify the internal or electrical assembly of DAS Server Shelf equipment.

• Protect the DAS Server Shelf from overheating; ensure that openings in the equipment are not blocked or covered. Never place the unit near any source of heat.

• Handle with care; rough treatment may damage sensitive components.

• Always turn off the power to the DAS Server Shelf before moving it.
