DECrepeater 200 INSTALLATION DECrepeater 200 Configuration Considerations
In a 1Obase5 to 1Obase5 configuration, the repeater has two Attachment Unit Interface (AUI) ports. The AUI port is Ethernet compatible and is designed to comply with IEEE 802.3. DECrepeater 200 units can connect 10base5 LAN segments with a maximum of 500 m (1640 ft) per segment.
In a 10base5 to FOIRL configuration, the repeater has two different interface ports. Port A is an AUI port and port B is a fiber optic interface port. The fiber optic interface is compatible with the IEEE 802.3 FOIRL specification and offers multifiber support.
A maximum of four DECrepeater 200 units can be used to connect five segments of a LAN. Of the five segments, a maximum of three can be 10baseS coaxial segments. This rule applies to both local and remote repeaters.
Basic Configuration Rules
1. If the repeater connects to an IEEE 802.3 transceiver, such as the H4005, the transceiver cable must be an IEEE 802.3 compliant transceiver cable (BNE3H/K/L/M or BNE4C/D). If an H4005 is used, it must have heartbeat disabled.
2. If the repeater connects to an Ethernet transceiver, such as the H4000, the transceiver cable can be either Ethernet or IEEE 802.3 compliant.
3. IEEE 802.3 transceiver cables and Ethernet transceiver cables cannot be interconnected.
4. Maximum length for the transceiver cable cannot exceed 50 m (164 ft).
5. Remote (fiber optic) repeaters can be used in one of two ways:
a. Repeater-to-repeater application: Two remote repeaters are joined by a fiber optic link. Each repeater is connected to a separate standard baseband Ethernet segment via a transceiver and a transceiver cable.
b. Bridge-to-repeater application: One remote repeater is connected to a LAN Bridge by a fiber optic link. The repeater and the bridge are connected to separate standard Ethernet seg-ments via a transceiver and a transceiver cable. The maximum length of a single fiber optic link between the bridge and repeater is 1.5 kilometers.

Figure 2 shows a local DECrepeater 200 connecting two LANs that are separated by fewer than 100 m (328 ft). This is the maximum combined length of the local repeater's transceiver cables.

The DECrepeater 200 cannot be used in the following situations.
• As a standby repeater in any repeater configuration
• As a replacement for a remote DEREP unless both ends of the fiber optic cable connection use DECrepeater 200 repeaters
• With a remote LAN Bridge 100

DECrepeater 200 INSTALLATION
Device Placement
The DECrepeater 200 can be installed in a variety of environments, including offices and computer rooms, as long as the environmental requirements are met. The unit can be placed on a desk, or a table, or it can be mounted in a standard 19-inch Radio Electronics Television Manufacturers Association (RETMA) rack or Satellite Equipment Room rack. For rack mounting see Figure 5. A wall/partition mounting kit is available that allows the repeater to be suspended from a partitioned office wall. Installation instructions are provided with the installation kit (P /N: H039).

Preinstallation Steps
Before installing the DECrepeater 200, use the following checklist to ensure that site preparation is complete.
I. Verify access to ac power.
2. Ensure that the appropriate baseband network interface is installed; that is, the H4005 and the required transceiver cabling is in place, tested, and tagged.
3. Ensure that the fiber optic cables (if required) are installed, certified, and tagged.
4. Ensure that the wall/partition mounting bracket kit is installed (if required).
5. Ensure that the power outlet matches the power requirements of the repeater and is within 1. 8 m (6 ft) of the installation location.
6. Ensure that the environmental requirements are met.
7. Ensure that there is adequate space for ventilation and for maintenance access.
