Installing the High Speed Serial Interface (HSSI) Card

The High Speed Serial Interface (HSSI) card provides one full-duplex, high-speed (DS3/STS-1: 44-52 Mbps) NRZ-encoded HDLC serial port with minimal modem control.

CAUTION:

The test device hssi command (at the Monitor prompt), does not work properly. If you run this command, the HSSI card fails and you need to restart your router.

This will never recover.

Hardware Installation

To install the HSSI (pronounced `hissy') card in your router, follow the instructions in the following sections:

Opening the Chassis

 To open the router's chassis . . .

1. Remove the router's front bezel.

2. Depress the AC power switch on the back panel to the OFF position (0).

3. Unplug the AC power cord from the electrical outlet.

4. Loosen the four spring-back screws on the back panel of the chassis and lift the cover off the chassis.

Removing a HSSI Card

To remove a HSSI card . . .

1. Remove any cables connected to the interface card.

2. Loosen the two spring-back screws near the card's rear bracket.

3. Carefully lift the card out of the chassis.

Installing a HSSI Card

 To install a HSSI card . . .

1. Remove any blank plates covering the front and back of the I/O slots.

Note: The HSSI card should only be installed in slots 0, 1, or 3.

2. Handling the network interface card by its sides, slide the bracket pins of the network interface card through the holes on the top of the chassis frame and then through the I/O slot guide at the front of the chassis.

3. Attach the card to the 96-pin DIN connector in the chassis body.

4. Align the two spring-back screws with the holes on the card's rear bracket and tighten the screws.

5. Connect the appropriate cable(s) to the interface card.

6. Close the chassis using the procedure described in Closing the Chassis.

Closing the Chassis

 To close the router's chassis, do the following:

1. Slide the chassis cover to its original position and secure it to the chassis frame by tightening the four spring-back screws.

2. Reconnect the power cord.

3. Depress the AC power switch on the back panel to the ON position ( | ).

4. Re-attach the router's front bezel.

Software Configuration

 After installing the interface card and powering on the router, run the add device command from the Config> prompt to configure the device:

Config>add device

The choices/prefixes are (a complete list):

ETHERNET
FDDI
HSSI
QUAD-SERIAL
TOKEN-RING

To add the HSSI card . . .

Config>add device hssi
Device Slot # (0-4) [0]?

Device Name [HSSI0]?
Adding device HSSI0 as interface 0
Defaulting Data-link protocol to PPP

To change the data-link protocol from PPP to Frame Relay . . .

Config>set DATA-LINK FRAME-RELAY 0

Monitoring

The following sections provide information on monitoring the HSSI card.

Internal Lights and Status

There are four lights on the HSSI card that are visible only when the cover is off the router. These lights indicate the diagnostic and load status of the card. When the HSSI card is loaded, operational, and idle, the OK light is lit. After resetting a router and before loading the card, the lights flash continually in sequence. Any other pattern indicates either a power-on test or failure mode.

It should never be necessary to consult these lights during the normal operation of the HSSI card or the router.

External Lights and Status

There are six lights which are visible on the front of the HSSI card that indicate the operational status of the card.

To get a quick indication of the status of the HSSI card, enter list configuration at the monitoring (+) prompt.

Event Logging System Monitoring

Additional operational information is available via the Event Logging System (ELS) HSSI subsystem. To enable HSSI event logging, enter display subsystem hssi all at the ELS Config> or ELS> prompt:

+event
Event Logging System user console
ELS>display subsystem hssi all
ELS>

or

*config
Gateway user configuration
Config>event
Event Logging System user configuration
ELS config>display subsystem hssi all

If the HSSI.002 event occurs, the router reports a status code.

The following table lists the defined HSSI.002 status codes and their meanings:

Code Meaning Action
8000

 There is already an unacknowledged request to the card.

8602

 The driver state is inappropriate for downloading.

8102

 The device was not present at restart.

8402

 The driver did not recognize the common MAC-layer request.

 The interface should disable itself. Call OpenROUTE Networks customer service.

8902

 Command flushed, as part of self-test or initialization.

 The interface should recover by itself.

8C04

 ROM indicates that the download address is out of range.

8A04

 ROM indicates that the download buffer is too long.

8804

 ROM indicates that the download checksum is wrong.

8404

 ROM indicates that the start address is out of range.

8504

 ROM does not recognize the request.

8F04

 ROM does not recognize the request.

 The interface should disable itself. Call OpenROUTE Networks customer service.

8502

 Download firmware does not like its configuration.

 Consider reducing the MTU size.
