The connection to Subnet .88 fiber is currently torturous: ~100' away
as the neutrino flies; ~150' rectilinearly in hall coordinates
(90' west, 45' north, 20' up); ~400' as connected. The packet error rate
used to run 25-40% on the slightly shorter connection to Subnet .90,
but this did not go down noticably when the total run was
reduced from ~440' to ~340' on Sep. 15, 1998. The connection
to Subnet .88 did lower the error rate: it's now 0-5%.
The principle hardware for this 10-Mbit (IEEE 802.3) Ethernet is:
Note: AUI port connections must use a transceiver, but none should be used if the RJ-45 port is selected.
The network was reconfigured (mid-September, 1998) to exploit the Etherswitch more fully; the external network connection is still 10-Mbit/second, but the agregate local bandwidth is six times more than the old one. Some basic information:
The Switch is documented in the "Kalpana EtherSwitch EPS-1500 Design and Installation Guide;" TPC has a copy. Cisco acquired Kalpana in 1994, and has additional information: a search of www.cisco.com finds FAQ-type info, but access takes a Cisco contract number, so the current state of some "future functionality" issues in the documentation (e.g., diagnostics through a backpanel RS-232 port and the SNMP card) is unclear.
The EPS-1500 starts up running ~3 minutes of diagnostics, shown by LED's on the cards; the system address table for the ports is initially empty, then fills as packets are successfully routed. The reset switch on the back panel (documentation, page 5-3) can clear the address tables. Devices moved between ports while the switch is running are detected and the tables updated within a second or two; no reset is required.
A link consists of two pairs of polarized lines: transmit and receive. The polarized lines must match, of course, but whether the link should, for example, connect transmit at one end to receive or to transmit at the other end, depends on the type of device. Frequently, the convention can be set by the devices at one or both ends; or by the connecting cable.
Important: to connect the tranceiver on a simple EPP's AUI to a hub, or from the 10BaseT on a 211B when MDI is selected, use:
The LED's on the simple EPP's mean the following:
(Top)
Amber: Internal diagnostics running
Red: Packet forwarded to another EtherSwitch port
Yellow: Packet received from port
Green: Packet transmitted to port
(Bottom)
The 211B Ethernet Packet Processors - with AUI and RJ-45
connectors, 3 DIP switches and 8 LED's - are mounted in slots 1, 3, 5,
7, 9, 11 of the lower EtherSwitch. They are similar, but not
identical, to cards discussed on pages 5-6 and 5-6.1 of the "Kalpana
EtherSwitch EPS-1500 Design and Installation Guide." One DIP switch
selects MDI or MDI-X, for cable/device compatibility; another DIP
switch selects between enabling the AUI or the RJ-45 port; the
function of the additional, third DIP switch is unknown.
A connection to the AUI port is always via a transceiver; and it is said that a transceiver should not be attached to the AUI port when using the 10Base-T connection.
The 4 right-hand LED's on the 211B's are analogous to those on the simple EPP's (though colors differ); the 4 left-hand LED's are different:
(Top)
(Left LED Column) (Right LED Column)
Yellow: F = Meaning unknown. Yellow: Internal diagnostics running.
Green: L = LINK receive signal good. Green: Packet forwarded to another EtherSwitch port.
Green: X = MDI-X cross-connect enabled. Green: Packet received from port.
Green: A = AUI connector (not RJ-45) enabled. Green: Packet transmitted to port.
(Bottom)
The 211B DIP switches are:
DIP Switch Left Position Right Position ------------------------------------------------ 3 (Top): Unused ? Unused ? 2 (Middle): MDI MDI-X (default) 1 (Bottom): AUI (default) 10Base-T
If MDI-X mode is selected, as in our setup, Port 8 is a normal hub port; with Port 8 attached to the EtherSwitch, the unit effectively acts as a repeater and fan-out for Port 8. The other seven ports on each MicroRepeater should either be divided between several, low-activity devices, or between devices talking mostly to each other.
As of 08-SEP-1998, the twelve EtherSwitch slots holding EPP's are allocated as follows:
Port Card Configuration
----------------------------------------------------------------------------
1 211B Nothing
2 EPP Transceiver -> nothing
3 211B Nothing
4 EPP Transceiver -> to Control Room for external network
5 211B Nothing
6 EPP Transceiver -> straight 10BaseT cable -> lower, left CentreCOM hub
7 211B 10BaseT cable -> transceiver -> Slow Controls MVME Ethernet
8 EPP Transceiver -> straight 10BaseT cable -> lower, right CentreCOM hub
9 211B RJ-45 port -> straight 10BaseT cable -> upper, left CentreCOM hub
No link light appears on the CentreCOM because the EPP is set to MDI-X, not MDI
10 EPP Transceiver -> straight 10BaseT cable -> upper, right CentreCOM hub
11 211B No connection
12 EPP Transceiver; no connection
