Table 1-3. Possible SG-1 Options

 

If you want to add:

Then:

 

 

 

 

 

 

SG-1 chassis

Consider installing the first chassis in the top

 

 

 

position of a rack to allow for further expansion

 

 

 

below it.

 

 

 

 

 

 

Fast Ethernet Port

Add a Rear I/O card on the corresponding rear

 

 

 

slot of an SCC that Fast Ethernet access is

 

 

 

desired.

 

 

 

 

 

 

Service Creation Cards:

 

 

 

 

 

 

 

VRRP

Use an SCC of the same type in any slot (1

 

 

 

through 16). Consider placing cards participating

 

 

 

in functional groups in adjacent slots for ease of

 

 

 

identification.

 

 

 

 

 

 

Redundancy

Add an additional SCC, of the same type, in slots

 

 

 

1 through 16 to have an additional card that

 

 

 

provides the same service in the event of a card

 

 

 

or connectivity failure.

 

 

 

 

 

POWER REQUIREMENTS

The following specifies the power versions available for the SG1 chassis, then specifies the power requirements for your facility relative to the SG1 power version you selected.

SG-1 Chassis

The SG-1 chassis provides four 100 to 240 Vac (50 to 60 Hz) power supplies with AC power connectors. You must install one power supply for every five Service Creation Cards installed in a chassis (three power supplies are required for a chassis having slots 1 through 16 fully populated). If you want redundant power, install an additional power supply in an open power module slot. It is recommended to have one power module above the minimum to provide uninterrupted service should a power module fail.

Facility Requirements for AC Power

Verify that the facility AC power source for the primary connection falls within the recommended voltage range of 110 to 220 Vac with a maximum current of 10 amps for 110 Vac and 5 amps for 220 Vac.

BLANK FACEPLATE REQUIREMENT

When slots in an SG-1 chassis do not contain a card, the slot must be covered with a blank faceplate to prevent personnel contact with back panel connectors and to maintain proper air flow within the chassis.

ENVIRONMENTAL REQUIREMENTS

The SG-1 chassis has an ambient operating temperature range of +32 to +104° F (0 to +40° C) with a maximum humidity of 95% when installed according to the instructions in this installation manual.

The storage temperature range is from -4 to +158° F (-20 to +70° C).

SYSTEM CABLING REQUIREMENTS

You will complete only the cabling appropriate for the cards installed in the chassis.
